Problem-Solving: How to Identify Problems, Analyze Root Causes, and Choose the Best
Solutions Using Practical Frameworks and Methods?

People face problems every day in their personal, professional, academic, and social lives. These problems differ in size, complexity, and impact, but they share one common characteristic: they require organized thinking to reach the best possible solution. However, many people jump directly to solutions before understanding the real problem, which leads to repeated mistakes, wasted time, effort, and resources.

Problem-solving is one of the most important mental skills a person can develop because it does not depend on intelligence alone, but also on the ability to accurately define the problem, analyze its causes, evaluate alternatives, choose the most appropriate solution, and then review and continuously improve the results. For this reason, companies, institutions, militaries, engineering teams, doctors, and scientists rely on organized methodologies and frameworks that help them deal with complex problems more effectively.

In this article, we will explore the concept of problem-solving, its importance, and the reasons why people fail to solve problems correctly. We will then examine some of the most widely used practical frameworks around the world, such as the Plan, Do, Check, Act (PDCA Cycle), Root Cause Analysis using the Five Whys (5 Whys) technique, First Principles Thinking, Design Thinking, and the Observe, Orient, Decide, Act (OODA Loop). We will also learn when to use each framework and how to combine them to reach more accurate and sustainable solutions.

Problem-Solving

1 - What Is Problem-Solving?

Problem-solving is one of the most important mental skills people use in every aspect of their lives, whether they are making a personal decision, managing a project, resolving a conflict, facing a challenge at work, or seeking to develop a new product. Life is naturally full of situations that require finding solutions, which is why the ability to deal with problems systematically is one of the skills with the greatest impact on personal and professional success.

Problem-solving refers to the systematic process of identifying a problem, understanding its causes, analyzing it, then selecting the best possible solution, implementing it, and evaluating its results. Therefore, problem-solving is not an independent theory, but a practical skill that relies on a set of tools, models, and frameworks that help people think in an organized way rather than relying solely on guesswork, intuition, or emotional reactions.

- Why Is Problem-Solving a Skill Rather Than a Theory?

A theory describes how a particular phenomenon works, whereas a skill is an ability that can be learned, developed, and improved through practice. Therefore, problem-solving is similar to skills such as leadership, communication, or decision-making, because anyone can become better at it by practicing the use of appropriate methodologies and learning from previous experiences.

There is no single method that works for every problem because the nature of each problem differs from another. Some problems may require logical analysis, while others require creativity, collaboration, experimentation, or rapid decision-making under pressure.

- When Do We Say That There Is a Problem?

A problem exists when there is a gap between the current situation and the situation we want to reach, and we do not immediately know how to close that gap.

The goal may be clear, but the path toward it may not be, the real causes of the problem may be unknown, or there may be several possible solutions without knowing which one is best.

- The Basic Elements of Any Problem:

Element Description
Current situation. The reality we are experiencing now.
Desired situation. The outcome we want to reach.
Gap. The difference between reality and the goal.
Obstacles. The factors preventing us from reaching the goal.
Solution. The action that reduces or eliminates the gap.

- Characteristics of Effective Problem-Solving:

  • Relies on facts and evidence.
  • Begins by understanding the problem before searching for a solution.
  • Distinguishes between causes and symptoms.
  • Compares multiple alternatives.
  • Considers short-term and long-term consequences.
  • Measures the success of the solution after implementation.

- The Difference Between Problem-Solving and Decision-Making:

Many people confuse these two concepts, even though they are not the same thing. Problem-solving focuses on removing the obstacles that prevent us from reaching a particular goal, whereas decision-making focuses on choosing the best alternative among several options, whether or not a problem exists.

Problem-Solving Decision-Making
Addresses an existing problem. Chooses the best alternative.
Searches for the root cause. Compares the available options.
May involve several decisions. Can occur even without a problem.
Ends when the problem is resolved. Ends when the appropriate alternative is selected.

- Why Is Problem-Solving an Essential Skill in the Twenty-First Century?

In a rapidly changing world, a person's value is no longer measured by the amount of information they memorize, but by their ability to deal with new situations, understand complex problems, and develop innovative solutions to them. For this reason, problem-solving has become one of the most sought-after skills in the workplace, leadership, entrepreneurship, and education because it enables people to adapt to changes and make better decisions under different circumstances.

- Examples from Everyday Life:

  • A student investigates the reason for declining grades instead of simply studying for longer hours.
  • A manager addresses low team productivity by analyzing its causes rather than simply increasing working hours.
  • A store owner investigates the reason for declining sales before launching new promotions.
  • A person tries to improve their health by identifying the real cause of low energy instead of treating only the symptoms.
  • An engineer identifies the cause of a machine failure before replacing the entire machine.

2 - Why Do People Fail to Solve Problems?

Many people believe that the reason they fail to solve problems is a lack of intelligence or experience, but the reality is different. In most cases, failure is not caused by weak mental abilities, but by mistakes in the way people think or in how they understand the problem itself. People often spend hours or days trying to solve a problem that does not represent the real cause, while the root cause remains unaddressed.

This is why experts emphasize that the quality of a solution depends first on the quality of the problem definition. If the problem is not accurately defined, the solution is likely to be inappropriate, no matter how well it is executed.

- Jumping to Solutions:

This is one of the most common mistakes. When a problem appears, many people immediately rush to propose solutions before understanding its real causes. This often leads to treating symptoms instead of addressing the root of the problem.

For example, if a company's sales decline, the first solution that comes to mind may be to increase advertising, while the real cause could be poor product quality, poor customer service, or high prices.

- Confusing Symptoms with Root Causes:

Many of the problems we see are not the real problem, but merely symptoms of a deeper issue. When absenteeism increases in a company, for example, absenteeism itself is not necessarily the root cause. It may result from factors such as poor management, low job satisfaction, or exhaustion.

Therefore, treating only the symptoms may create a temporary impression that the problem has disappeared, but it often returns after a short period.

- Cognitive Biases:

Cognitive biases significantly affect problem-solving because they cause people to see what is consistent with their beliefs and ignore information that contradicts them. A person may reject a good idea simply because it came from someone they do not trust, or remain committed to an ineffective solution because they have already invested time or money in it.

Therefore, objective thinking is an essential condition for understanding a problem correctly.

- Relying on Assumptions Instead of Evidence:

A common mistake is for a person to base their analysis on expectations or personal impressions rather than facts and data. This can lead to decisions that appear logical on the surface but are based on inaccurate information.

- Looking at the Problem from Only One Perspective:

Complex problems are often the result of several interacting factors, but people tend to search for only one cause. Therefore, looking at a problem from a single perspective may lead to overlooking other influential factors.

This is where systems thinking becomes important because it helps people understand the relationships between all the elements of a problem rather than focusing on only one element.

- Rushing to Judgment:

Sometimes people make decisions within minutes based on previous experience or an inner feeling without gathering enough information about the current situation. Although intuition can be useful in some situations, it cannot replace systematic analysis when the problem is complex or has a significant impact.

- Poor Problem Definition:

If the problem is not clearly defined, it will not be possible to choose the appropriate solution. This is why it is often said in project management:

"Defining the problem correctly is half the solution."

The more accurately the problem is defined, the easier and faster it becomes to reach the right solution.

- The Main Reasons for Failure in Problem-Solving:

Reason Result
Jumping directly to solutions. Inappropriate solutions.
Treating only the symptoms. The problem returns.
Cognitive biases. Distorted understanding of the problem.
Relying on assumptions. Decisions based on inaccurate information.
Looking from only one perspective. Overlooking influential factors.
Rushing to judgment. Choosing weak solutions.
Inaccurate problem definition. Wasted time and resources.

- How Can You Avoid These Mistakes?

  • Define the problem accurately before thinking about the solution.
  • Separate symptoms from root causes.
  • Gather data before making judgments.
  • Look at the problem from multiple perspectives.
  • Ask more questions before providing answers.
  • Use a practical framework to organize your thinking instead of relying solely on intuition.

- Examples from Everyday Life:

  • A person buys a new phone because the battery drains quickly, then discovers that the problem was caused by apps running in the background.
  • A company disciplines its employees for low productivity, while the real cause is inadequate training.
  • A student spends additional hours studying, while the real problem lies in their study method rather than the number of hours.
  • A store owner repeatedly changes prices, while the real cause of declining sales is poor customer service.
  • A person treats a headache only with medication without investigating the underlying cause, such as lack of sleep, stress, or dehydration.

3 - A Systematic Problem-Solving Process

Although problems differ in type and in the environments in which they arise, most experts agree that the problem-solving process goes through a set of fundamental steps. These steps provide a general framework that can be applied in personal life, work, study, and management before using any specialized methodology such as the PDCA cycle, the Five Whys (5 Whys) technique, or other practical frameworks.

Following clear steps helps reduce impulsiveness, organize the thinking process, and increase the likelihood of reaching effective and sustainable solutions instead of settling for temporary solutions that only address symptoms.

- Step One: Problem Identification:

A problem cannot be solved if it has not been properly defined. Therefore, the first step is to describe the problem accurately and objectively while avoiding interpretations, accusations, or assumptions.

A problem definition should answer questions such as:

  • What is actually happening?
  • When did the problem begin?
  • Where does it occur?
  • Who is affected by it?
  • What is the extent of its impact?

The more accurately the problem is defined, the easier the remaining steps become.

- Step Two: Information Gathering:

After identifying the problem comes the stage of gathering data and evidence related to it. Facts, figures, and observations should be relied upon rather than personal impressions, rumors, or guesses.

In many cases, the data reveals that the problem is completely different from what was initially believed.

- Step Three: Cause Analysis:

This stage aims to discover the real cause of the problem rather than merely addressing its symptoms. Tools such as Root Cause Analysis and the Five Whys (5 Whys) technique are used here to uncover the deeper causes that led to the problem.

The clearer the real cause becomes, the more accurate and effective the choice of solution will be.

- Step Four: Generating Solutions:

After understanding the problem, the search begins for as many possible solutions as possible without judging them immediately. At this stage, quantity matters because having multiple options increases the likelihood of finding an innovative or more efficient solution.

Brainstorming, First Principles Thinking, or Design Thinking can be used to generate diverse solutions.

- Step Five: Evaluating Alternatives:

Not all solutions are equal in quality, so alternatives should be compared according to a set of criteria, such as:

  • Cost.
  • Time.
  • Risks.
  • Ease of implementation.
  • Long-term results.
  • Impact on other parties.

The alternative that achieves the best balance between benefits and costs is then selected.

- Step Six: Implementation:

A solution has no value if it remains merely an idea. Therefore, the decision must be converted into a clear action plan that includes responsibilities, a timeline, required resources, and a method for monitoring implementation.

- Step Seven: Evaluation:

After implementing the solution, its results must be measured to ensure that it actually addressed the problem. If the desired results are not achieved, the previous steps should be reviewed and the solution adjusted or another alternative selected.

Therefore, problem-solving is not a process that ends once a solution is implemented. It is an ongoing process based on learning, improvement, and feedback.

- Summary of the Problem-Solving Steps:

Step Objective
Problem identification. Understand what is actually happening.
Information gathering. Obtain accurate data.
Cause analysis. Discover the root cause.
Generating solutions. Produce as many alternatives as possible.
Evaluating alternatives. Choose the best solution.
Implementation. Turn the idea into reality.
Evaluation. Ensure the solution works and improve it.

- Why Are These Steps Important?

These steps form the foundation on which almost all problem-solving methodologies are built. Every practical framework, regardless of its name, attempts in one way or another to identify the problem, understand its causes, develop solutions, and evaluate their results. Therefore, understanding this general process makes learning specialized frameworks much easier.

- Examples from Everyday Life:

  • A student identifies the reason for declining grades, gathers information about their study method, analyzes the causes of poor performance, tries a new study approach, and then compares the results.
  • A restaurant owner notices a decline in the number of customers, gathers customer feedback, analyzes the causes, develops the menu, and measures the impact of the changes.
  • An employee experiences work-related stress, identifies the sources of stress, evaluates their priorities, creates a time-management plan, and reviews the results after several weeks.
  • An engineering team solves a production machine failure by gathering data, analyzing the causes, and then testing several solutions before adopting the final one.
  • An entrepreneur faces declining company profits, analyzes financial data and customer behavior, implements a new plan, and measures its impact regularly.

4 - Plan, Do, Check, Act (PDCA Cycle)

The Plan, Do, Check, Act (PDCA Cycle) is one of the world's most widely used methodologies for continuous improvement and problem-solving. It was developed to help organizations and individuals test solutions systematically and improve them gradually instead of relying on random trial and error or quick decisions.

Today, this cycle is used in many fields, including management, manufacturing, education, healthcare, software development, and quality management, because it provides a simple and organized way to analyze problems, test solutions, and learn from the results.

It is sometimes referred to as the Deming Cycle, after the American quality expert W. Edwards Deming, who helped popularize it worldwide, particularly in Japan after World War II.

- What Is the PDCA Cycle?

The cycle consists of four recurring stages, where the completion of one cycle leads to the beginning of a new cycle, allowing performance to be continuously improved and errors to be corrected along the way.

Stage Objective
Plan. Understand the problem and develop a plan for the solution.
Do. Apply the solution on a limited scale.
Check. Measure the results and compare them with the objectives.
Act. Adopt the solution, modify it, or repeat the experiment.

- Stage One: Plan:

The cycle begins by understanding the problem, gathering data, and analyzing the causes, followed by defining the desired objective and developing a clear plan for the solution. This is the most important stage because the quality of implementation depends directly on the quality of planning.

This stage usually includes:

  • Identifying the problem.
  • Gathering information.
  • Analyzing the causes.
  • Defining objectives.
  • Developing an implementation plan.

- Stage Two: Do:

After completing the planning stage, the solution is implemented, but it is preferable to begin on a small scale. This approach helps identify problems and errors before the solution is applied throughout the entire system.

Therefore, this stage serves as a practical experiment for testing the hypotheses developed during the planning stage.

- Stage Three: Check:

After implementing the solution, the results are measured and compared with the objectives defined beforehand. If the solution achieves the desired results, it may be possible to move to the next stage. If it does not, the reasons must be understood before proceeding.

This stage relies on data and indicators rather than personal impressions.

- Stage Four: Act:

If the solution proves successful, it is adopted and implemented on a larger scale. If the results are below expectations, the plan is modified or another solution is tested, and then a new cycle begins from the start.

This is why PDCA is called a continuous improvement cycle: it does not end with the first attempt, but instead relies on continuous learning and development.

- Why Is PDCA Effective?

  • Reduces risks by testing solutions gradually.
  • Encourages continuous learning.
  • Relies on data rather than guesswork.
  • Helps identify errors early.
  • Prevents problems from recurring.

- When Should It Be Used?

  • Improving service quality.
  • Solving recurring problems.
  • Developing processes.
  • Managing projects.
  • Improving personal performance.
  • Developing products.

- Advantages and Limitations:

Advantages Limitations
Simple and easy to apply. May be slow for urgent problems.
Relies on continuous improvement. Requires accurate measurement of results.
Reduces risks. Requires commitment to implementation and follow-up.
Promotes learning from mistakes. Is not sufficient on its own to identify root causes.

- Its Relationship with Other Frameworks:

PDCA is a general framework for managing the improvement process, but it does not itself identify the root cause of a problem. Therefore, it is often used together with Root Cause Analysis or the Five Whys (5 Whys) technique during the planning stage. First Principles Thinking can also be used when designing new solutions.

- Examples from Everyday Life:

  • A student develops a plan to improve their grades, tests it for a month, compares the results, and adjusts it if necessary.
  • A restaurant owner develops a new menu in one branch first before implementing it across all branches.
  • A team tests a new meeting approach for two weeks and then measures its impact on productivity.
  • A person starts a new fitness program, monitors the results, and then adjusts the plan according to their progress.
  • A company tests a new feature in its application with a small group of users before releasing it to everyone.

5 - Root Cause Analysis

After identifying the problem, the most important stage in the problem-solving process is determining the real cause that led to it. People and organizations often succeed in addressing the visible symptoms of a problem but fail to eliminate the actual cause, which leads to the problem recurring again and again. This is why Root Cause Analysis is one of the most important methodologies used in management, engineering, medicine, industry, and quality management, because it focuses on eliminating the source of the problem rather than simply addressing its consequences.

The goal of Root Cause Analysis is not to find someone to blame, but to understand the real causes that led to the problem so that its recurrence can be prevented in the future. This is why major organizations around the world rely on it when failures, quality issues, or project failures occur, because it provides long-term solutions rather than temporary fixes.

- What is Root Cause Analysis?

Root Cause Analysis is a structured methodology aimed at discovering the fundamental cause that led to a problem, so that eliminating this cause can prevent the problem from recurring or significantly reduce the likelihood of it happening again.

This approach differs from treating symptoms because it attempts to answer a more important question:

Why did the problem happen in the first place?

- The Difference Between Symptoms and Root Causes:

One of the most common mistakes is assuming that the first thing we notice is the cause of the problem, when in reality it may simply be a symptom of a deeper problem. Therefore, distinguishing between a symptom and a cause is fundamental to any successful analysis.

Symptom Root Cause
Declining sales. Poor product quality, or poor customer service.
Employees arriving late. Traffic congestion, a weak attendance system, or low motivation.
High error rate. Insufficient training, or unclear procedures.
Low student grades. Ineffective study methods, or poor time management.
Production machine breakdown. Lack of regular maintenance, or the end of a particular component's useful life.

- Why is Discovering the Root Cause Important?

Because treating symptoms alone is like wiping water from the floor while the faucet is still running. The problem may appear to have disappeared, but it will return as long as its true source remains unaddressed.

When the root cause is addressed, however, the likelihood of the problem recurring decreases significantly, and solutions become more sustainable and less costly in the long term.

- Steps of Root Cause Analysis:

  1. Define the problem accurately.
  2. Gather the relevant information and data.
  3. Identify all possible causes.
  4. Distinguish between symptoms and actual causes.
  5. Use appropriate analysis tools, such as the 5 Whys technique.
  6. Choose a solution that addresses the root cause.
  7. Monitor the results to ensure that the problem does not recur.

- The Most Common Root Cause Analysis Tools:

Several tools can be used to identify the true causes of problems. The analyst chooses the appropriate tool according to the nature and level of complexity of the problem.

Tool Use
5 Whys. Gradually reaching the root cause by repeatedly asking the question "Why?"
Fishbone Diagram. Organizing potential causes into major categories.
Pareto Analysis. Identifying the most influential causes.
Data Analysis. Discovering patterns and relationships between causes.

- When is Root Cause Analysis Used?

  • When the problem keeps recurring.
  • When there are financial or operational losses.
  • After accidents or failures.
  • In quality improvement.
  • In process improvement.
  • For recurring personal problems.

- Advantages and Limitations:

Advantages Limitations
Addresses the root of the problem. May take a long time.
Prevents problems from recurring. Requires accurate data.
Improves the quality of decisions. There may be more than one root cause.
Reduces costs in the long term. Depends on the quality of the analysis.

- The Relationship with the 5 Whys Technique:

Root Cause Analysis is a general methodology, while the 5 Whys technique is one of the most widely used tools within this methodology for reaching the true cause of a problem. Therefore, we will examine this technique in detail in the following section, because it represents one of the simplest and most effective approaches to problem analysis.

- Examples from Everyday Life:

  • A student is repeatedly late for school and discovers that the real cause is going to bed after midnight, rather than simply waking up late.
  • Customer complaints keep recurring, and the analysis reveals that the problem is not the employees but unclear customer service procedures.
  • A device repeatedly breaks down, and the technician discovers that the actual cause is overheating due to blocked ventilation openings.
  • A person experiences constant fatigue and discovers through analysis that the real causes are insufficient sleep and poor nutrition, rather than work pressure alone.
  • An online store's profits decline, and the analysis reveals that the primary cause is a slow website rather than weak advertising campaigns.

6 - The 5 Whys Technique

The 5 Whys technique is one of the simplest and most widely used Root Cause Analysis tools in the world, but it is also one of the most effective when applied correctly. It was developed within Toyota as part of its production system, with the aim of identifying the true causes of operational problems rather than merely treating their consequences.

This technique is based on a very simple idea: the first cause that comes to mind is rarely the true cause of a problem. Therefore, the analyst continues asking the question "Why?" repeatedly until reaching the fundamental cause that led to the problem.

Although its name refers to five times, the number five is not a fixed rule. The root cause may become clear after three questions, or the analysis may require seven questions or more, depending on the nature of the problem.

- What is the 5 Whys Technique?

It is an analytical method based on repeatedly asking the question "Why?", with each answer becoming the basis for the next question until the root cause of the problem is reached.

Visible problem ← Why? ← First cause ← Why? ← Second cause ← Why? ... until the root cause is reached.

- Why is This Technique Effective?

Because people naturally tend to explain problems through surface-level causes, while this technique pushes them to think more deeply and not stop at the first explanation that seems logical.

It also prevents people from jumping to solutions too quickly because it makes understanding the problem the initial focus before searching for the appropriate remedy.

- Steps for Applying the 5 Whys Technique:

  1. Clearly define the problem.
  2. Ask: Why did this problem occur?
  3. Use the answer as a new question: Why did that happen?
  4. Repeat the process until you reach the actual cause.
  5. Develop a solution that addresses the root cause, not the symptoms.

- Practical Example:

Suppose a student received low grades on an exam.

Question Answer
Why did I get a low grade? Because I did not prepare well for the exam.
Why did you not prepare well? Because I started studying late.
Why did you start late? Because I kept procrastinating on studying.
Why did you keep procrastinating? Because I did not have a study plan.
Why did you not have a plan? Because I do not use a time-management system.

We can see that the real problem is not the low grade, nor even starting to study late, but the absence of an effective time-management system.

- Another Example in the Workplace:

Question Answer
Why was the project delivery delayed? Because some tasks were not completed on time.
Why were they not completed? Because the team did not receive the necessary information.
Why did they not receive it? Because communication between departments was weak.
Why was communication weak? Because there was no clear mechanism for exchanging information.
Why was there no mechanism? Because the company had not established standardized communication procedures.

- Common Mistakes When Using the 5 Whys Technique:

  • Stopping at the first answer without going deeper.
  • Assuming causes without evidence.
  • Turning the analysis into a search for someone to blame.
  • Confusing symptoms with causes.
  • Insisting on asking the question five times even when the root cause has already been identified.

- When Should This Technique Be Used?

  • For recurring problems.
  • In quality improvement.
  • After failures occur.
  • For analyzing personal mistakes.
  • In project management.
  • In education and training.

- Advantages and Limitations:

Advantages Limitations
Easy to learn and apply. May produce incorrect results if the data is inaccurate.
Does not require complex tools. There may be several root causes at the same time.
Helps reach the source of the problem. Depends on the skill of the person conducting the analysis.
Reduces recurring problems. Less suitable for highly complex problems without additional tools.

- Relationship with the Other Frameworks:

The 5 Whys technique is often used during the planning stage of the PDCA cycle to identify the true cause of a problem. It can also be combined with First Principles Thinking to rebuild solutions from the ground up, or with Systems Thinking when the problem results from the interaction of multiple factors.

- Examples from Everyday Life:

  • A person is late for work every day and discovers that the real cause is going to bed late, rather than traffic congestion.
  • A person notices an increase in monthly spending and discovers that the real cause is the absence of a budget, rather than rising prices alone.
  • A computer repeatedly breaks down, and it turns out that the cause is dust accumulating inside the device, rather than the computer itself being underpowered.
  • A person's physical fitness declines, and they discover that the real problem is not a lack of exercise but a failure to maintain a consistent routine.
  • A small business fails, and the analysis reveals that the primary cause was inadequate market research before launch.

7 - First Principles Thinking

After identifying the root cause of the problem, the next stage is to search for the best possible solution. At this stage, many people make a common mistake: they search for ready-made solutions or imitate what others are doing without questioning whether that solution is actually appropriate for the problem they are facing. This is where First Principles Thinking becomes important, as it is considered one of the most powerful approaches to thinking used in solving complex problems and driving innovation.

This approach involves returning to the fundamental facts that cannot be simplified any further, and then rebuilding the solution from scratch instead of relying on assumptions, habits, or conventional methods. This is why scientists, engineers, and entrepreneurs use it when existing solutions are insufficient or when they want to create entirely new solutions.

- What is First Principles Thinking?

It is a way of thinking that involves breaking a problem down into its simplest fundamental elements, then rebuilding the solution based on facts, laws, and established principles rather than imitating previous solutions or relying on assumptions.

Do not ask: "How do people solve this problem?" Instead, ask: "What are the fundamental facts underlying this problem?"

- Why Does This Approach Help Solve Problems?

Because many traditional solutions are based on assumptions that may be valid under certain circumstances but are not fixed laws. When a person analyzes a problem from scratch, they may discover that many of the limitations they believed were real are actually nothing more than habits, beliefs, or methods that people have become accustomed to following.

Therefore, First Principles Thinking is not merely about improving old solutions; it can also mean completely redesigning them when necessary.

- Steps for Using First Principles Thinking:

  1. Define the problem accurately.
  2. Break the problem down into its fundamental elements.
  3. Identify the facts that cannot be disputed.
  4. Eliminate unnecessary assumptions.
  5. Rebuild the solution from the fundamental principles.

- Practical Example:

Suppose someone wants to learn a new language but believes that doing so requires attending expensive courses.

Using First Principles Thinking, they would begin by asking different questions:

  • What is the real goal? Learning the language.
  • What makes a person learn any language? Listening, reading, practice, and repetition.
  • Does this require an expensive course? No.
  • Therefore, a plan can be designed around books, applications, and daily conversation.

The solution changed completely because the person stopped thinking about the method and focused on the fundamental principles of learning.

- The Difference Between First Principles Thinking and Reasoning by Analogy:

First Principles Thinking Reasoning by Analogy
Builds the solution from scratch. Imitates existing solutions.
Relies on fundamental facts. Relies on previous experience.
Encourages innovation. Encourages gradual improvement.
Suitable for new problems. Suitable for recurring problems.

- When Is It Used?

  • When traditional solutions do not work.
  • When developing new products.
  • In entrepreneurship.
  • In innovation.
  • For complex problems.
  • When seeking to reduce costs or improve efficiency.

- Advantages and Limitations:

Advantages Limitations
Encourages innovation. Requires time and effort.
Reveals false assumptions. May be difficult for beginners.
Builds more efficient solutions. Not necessary for simple problems.
Encourages independent thinking. May require deep knowledge of the field.

- Relationship with the Other Frameworks:

After the 5 Whys technique helps identify the root cause of the problem, First Principles Thinking can be used to design new solutions that may not have existed before. If the goal is to develop a product or service focused on user needs, however, Design Thinking is the more appropriate framework, which we will explore in the following section.

- Examples from Everyday Life:

  • A person redesigns their monthly budget from scratch instead of trying to reduce expenses randomly.
  • A teacher develops a new way of explaining lessons instead of repeating the traditional approach.
  • An entrepreneur rethinks how to deliver their service based on customers' fundamental needs.
  • An engineer designs a new product based on the fundamental properties of materials rather than copying competing products.
  • A person reorganizes their entire day after identifying the activities that actually provide the greatest value.

8 - Design Thinking

Not all problems are technical, mathematical, or logical. Some problems are related to people themselves, such as improving customer experience, developing services, designing products, improving education, or healthcare. In such cases, analyzing data alone is not enough; it is also necessary to understand the needs of the people who will use the solution. This is why Design Thinking emerged as a methodology that places people at the center of the problem-solving process.

Design Thinking is based on understanding users' needs first, then designing solutions that meet those needs in a practical way, testing them, and continuously improving them. For this reason, it has become widely used in companies, universities, government institutions, and startups because it helps develop innovative solutions based on reality, rather than assumptions.

- What is Design Thinking?

Design Thinking is a methodology for solving complex problems that focuses on understanding the people affected by the problem, then creating solutions that meet their real needs through experimentation and continuous development.

Do not start by asking: "What solution do I want?" Instead, start by asking: "What does the user actually need?"

- Why is Design Thinking different from other frameworks?

Most problem-solving methodologies focus on analyzing causes and choosing the best solutions from the perspective of the person conducting the analysis, whereas Design Thinking starts from a different perspective. It first seeks to understand the human experience, feelings, and needs, and then builds the solution around them.

This makes this framework particularly suitable when the goal is to improve user experience, develop a service, or innovate a new product.

- Stages of the Design Thinking Process:

Stage Goal
Empathize. Understand the user's needs and feelings.
Define. Formulate the problem accurately.
Ideate. Generate as many possible solutions as possible.
Prototype. Create a simple model of the solution.
Test. Test the solution and improve it.

- Stage One: Empathize:

The process begins by understanding the people who are experiencing the problem. This is done through observation, interviews, asking questions, and trying to see the problem from their perspective instead of relying on assumptions.

- Stage Two: Define:

After gathering information, the problem is reformulated accurately so that it reflects the user's real needs, rather than the perceptions of the designer or the organization.

- Stage Three: Ideate:

At this stage, the team is encouraged to generate as many ideas as possible without criticizing them initially. The goal is to expand the range of possibilities before selecting the most suitable solution.

- Stage Four: Prototype:

Instead of building the final product immediately, a simple prototype is created to test the idea quickly and at the lowest possible cost.

- Stage Five: Test:

The prototype is tested with real users, then their feedback is collected and used to improve the solution, modify it, or completely redesign it if necessary.

For this reason, Design Thinking is not a linear process, but an iterative one, in which it is possible to return to any stage whenever new information emerges.

- When is it used?

  • Product design.
  • Service development.
  • Improving customer experience.
  • Education.
  • Healthcare.
  • Entrepreneurship.

- Advantages and limitations:

Advantages Limitations
Focuses on human needs. May take a long time.
Encourages creativity. Requires user participation.
Reduces the likelihood of product failure. Not suitable for every type of technical problem.
Relies on experimentation and continuous improvement. May require several prototypes.

- Difference between Design Thinking and First Principles Thinking:

Design Thinking First Principles Thinking
Focuses on user needs. Focuses on fundamental facts.
Relies on empathy and experimentation. Relies on logical analysis.
Suitable for products and services. Suitable for innovation and solving complex problems.
Evolves through prototypes. Built from scratch.

- Relationship with the other frameworks:

After using Root Cause Analysis to discover the problem and First Principles Thinking to rebuild the solution, Design Thinking helps ensure that the solution meets the needs of real users. When the environment is changing rapidly and requires repeated decision-making within a short period of time, the Observe, Orient, Decide, Act Loop (OODA Loop) becomes more appropriate, which we will explore in the next section.

- Examples from everyday life:

  • A teacher designs a new way to explain lessons after observing the difficulties students face.
  • A restaurant develops a new menu based on customers' opinions, rather than only on management's preferences.
  • A company modifies its application after observing how customers actually use it.
  • A hospital redesigns its patient reception procedures to reduce waiting time.
  • An entrepreneur develops a new service after interviewing potential customers and understanding their actual needs.

9 - Observe, Orient, Decide, Act Loop (OODA Loop)

In some situations, people do not have enough time to conduct a lengthy analysis, build prototypes, or test several solutions before making a decision. Conditions may change within minutes, or even seconds, making the ability to adapt quickly more important than finding the perfect solution. This is why the Observe, Orient, Decide, Act Loop (OODA Loop) was developed to help individuals, teams, and organizations make fast and effective decisions in changing environments.

This methodology was developed by American military pilot John Boyd while studying aerial combat, and later spread to fields such as management, business, security, medicine, sports, and even everyday life because it helps people respond quickly to changing events instead of becoming rigid or delaying decisions.

- What is the OODA Loop?

The OODA Loop is a decision-making model based on four recurring stages, with the cycle continuing as information and surrounding conditions change.

Stage Goal
Observe. Gather information and observe what is happening.
Orient. Analyze the information and understand the situation.
Decide. Choose the best possible course of action.
Act. Implement the decision quickly, then return to observation.

- Stage One: Observe:

The cycle begins by gathering as much information as possible about the current situation, such as data, events, other people's actions, and any new changes that may affect the decision.

The more recent and accurate the information is, the more effective the remaining stages become.

- Stage Two: Orient:

This is the most important part of the loop because it does not depend only on information, but also on how that information is interpreted. At this stage, the person compares the data with previous experience, knowledge, goals, and the surrounding environment in order to build an accurate understanding of the situation.

Two people may reach completely different decisions despite having the same information because they interpret that information differently.

- Stage Three: Decide:

After understanding the situation, the best available decision at that moment is selected. The decision does not have to be perfect; it only needs to be appropriate given the current information because the loop will continue, and the decision can be adjusted later if new information emerges.

- Stage Four: Act:

The decision is implemented quickly, and its results are then observed immediately. If the situation changes, the loop begins again with observation, allowing continuous adaptation to the environment.

For this reason, OODA is a continuous loop rather than a process that ends after a decision is implemented once.

- Why is OODA effective?

  • Encourages rapid adaptation.
  • Helps with decision-making under pressure.
  • Relies on continuous learning.
  • Allows decisions to be adjusted when conditions change.
  • Reduces the risk of rigidity or waiting for complete information.

- When is it used?

  • Crisis management.
  • Leadership.
  • Financial markets.
  • Managing rapidly changing projects.
  • Sports.
  • Everyday situations that require a rapid response.

- Advantages and limitations:

Advantages Limitations
Fast and flexible. May lead to poor decisions if information is incomplete.
Adapts to continuous changes. Depends on the decision-maker's experience.
Helps with working under pressure. Less suitable for problems requiring lengthy analysis.
Encourages continuous learning. Frequent adjustments may lead to instability if used incorrectly.

- Difference between OODA and PDCA:

OODA Loop PDCA Cycle
Focuses on rapid adaptation. Focuses on continuous improvement.
Suitable for changing environments. Suitable for process improvement.
Makes decisions quickly. Relies on advance planning.
Used in crises and competition. Used in quality and development.

- Relationship with the other frameworks:

While PDCA helps improve processes gradually, Root Cause Analysis helps identify the source of the problem, and Design Thinking focuses on user needs, the OODA Loop is distinguished by its ability to make rapid decisions when the environment is unstable or information is constantly changing.

- Examples from everyday life:

  • A driver notices sudden traffic congestion, assesses the situation, chooses an alternative route, and then monitors traffic again.
  • A trader monitors market movements and quickly changes the decision when new information appears that affects prices.
  • A football coach adjusts the game plan during a match after observing a change in the opposing team's playing style.
  • An emergency physician manages a patient whose vital signs are constantly changing by reviewing the information and adjusting treatment according to new developments.
  • A project manager monitors progress daily and redistributes tasks whenever new obstacles emerge.

10 - How to Choose the Right Problem-Solving Framework?

After learning about the most important problem-solving methodologies, an important question may arise: Which framework should I use? The answer is that there is no single methodology that fits every problem. Each framework has a specific purpose, strengths, and situations in which it is more effective than others. Therefore, choosing the right framework depends on the nature of the problem, the available information, the time available, and the outcome you are seeking to achieve.

A common mistake is to believe that one particular framework is better than all the others, while in reality, each framework was designed to solve a different type of problem. Just as a doctor uses different tools depending on the patient's condition, a thinker, manager, or entrepreneur uses the framework that best fits the nature of the situation.

- When should you use each framework?

Framework Best Use
PDCA Cycle. Continuous process improvement.
Root Cause Analysis. Discovering the real cause of the problem.
5 Whys. Analyzing simple and moderately complex problems.
First Principles Thinking. Creating new solutions and challenging assumptions.
Design Thinking. Designing human-centered products and services.
OODA Loop. Making rapid decisions in changing environments.

- How do you determine the appropriate framework?

If the problem... Then use...
Keeps recurring. Root Cause Analysis or 5 Whys.
Requires gradual improvement. PDCA Cycle.
Requires an innovative solution. First Principles Thinking.
Is related to users or customers. Design Thinking.
Changes rapidly. OODA Loop.
Involves multiple factors. Combine more than one framework.

- Should you use only one framework?

In reality, successful organizations rarely rely on only one framework. In many cases, more than one framework is used within the same problem because each framework serves a different function in the process of thinking, analysis, and decision-making.

For example, you might begin with Root Cause Analysis to discover the source of the problem, then use First Principles Thinking to rebuild the solution, then apply Design Thinking to test the solution with users, and finally use the PDCA Cycle to continuously improve it after implementation.

- Do not search for the perfect framework:

The goal is not to use as many methodologies as possible, but to choose the simplest framework capable of solving the problem effectively. The right framework is the one that helps you reach a better decision with the least possible complexity, time, and resources.

There is no methodology that works for every problem, but there is a methodology suitable for every problem.

- Examples from everyday life:

  • A student experiencing a decline in academic performance uses the 5 Whys technique to discover the real cause, then applies the PDCA Cycle to improve the study plan.
  • A company develops a new product using Design Thinking, then uses PDCA to improve it after launch.
  • A manager faces a sudden crisis at work and uses the OODA Loop to make rapid decisions until the situation stabilizes.
  • An entrepreneur redesigns their business model using First Principles Thinking after discovering that traditional solutions are no longer suitable.
  • A quality team uses Root Cause Analysis to determine why failures keep recurring before developing an improvement plan.

11 - How to Combine Multiple Frameworks to Solve One Problem?

In reality, real-world problems are rarely simple enough to be solved by a single framework. The problems faced by individuals and organizations are often caused by multiple factors, affected by changing conditions, and influenced by human, technical, and economic factors at the same time. Therefore, experts do not rely on a single methodology; instead, they combine several frameworks so that each framework complements the strengths of the others.

This can be compared to a doctor who does not rely on a single device to diagnose a patient, but uses a clinical examination, laboratory tests, imaging, and medical history to reach an accurate diagnosis. Problem-solving works in the same way; each framework provides a different perspective for understanding the problem and reaching the best possible solution.

- An Integrated Practical Model for Problem-Solving:

Suppose a company notices a continuous decline in customer satisfaction and begins losing some of its customers to competitors. How can multiple frameworks be used to solve this problem?

Stage Appropriate Framework Goal
Understand the problem. Root Cause Analysis. Identify the real cause of declining customer satisfaction.
Explore the causes more deeply. 5 Whys. Reach the fundamental cause of the problem.
Innovate the solution. First Principles Thinking. Redesign the solution from scratch without assumptions.
Design the service. Design Thinking. Ensure that the solution meets customers' needs.
Implement the solution. PDCA Cycle. Implement the solution and continuously improve it.
Handle changes. OODA Loop. Make rapid decisions if conditions change.

- Practical Example:

Imagine that an online store notices a significant decline in the number of orders. At first glance, it may appear that the cause is weak marketing, but following only one framework could lead to an incorrect conclusion.

Using Root Cause Analysis, the team discovers that the problem is not the number of visitors, but a decline in the checkout completion rate.

The team then uses the 5 Whys technique to discover that many customers are leaving the checkout page.

After that, the team uses First Principles Thinking to rethink the entire checkout process instead of merely making minor changes to the existing design.

The team then applies Design Thinking to conduct user interviews and test different versions of the checkout page until the easiest-to-use design is identified.

After launching the new version, the team uses the PDCA Cycle to monitor the results and continuously improve them.

If sudden changes appear in the market or customer behavior changes, the team uses the OODA Loop to make rapid decisions and adjust the strategy according to the new information.

- Why is combining frameworks more effective?

  • Because each framework answers a different question.
  • Because real-world problems rarely have only one cause.
  • Because some frameworks focus on analysis, while others focus on innovation, implementation, or improvement.
  • Because combining frameworks reduces the likelihood of reaching superficial conclusions.
  • Because it allows you to move from understanding the problem to implementing the solution in an organized way.

- A Suggested Practical Sequence:

Question Framework That Answers It
What is the real cause of the problem? Root Cause Analysis.
Why did this cause occur? 5 Whys.
How can a new solution be built? First Principles Thinking.
Does the solution suit the users? Design Thinking.
How do we implement and improve it? PDCA Cycle.
How do we adapt to changes? OODA Loop.

An excellent thinker does not possess a single framework; they possess a toolbox and know when to use each tool and when to combine them.

- Examples from everyday life:

  • A student uses the 5 Whys to determine the cause of declining grades, then applies the PDCA Cycle to improve their study method and uses the OODA Loop to adjust the plan if the exam schedule changes.
  • A store owner identifies the cause of declining sales through Root Cause Analysis, then redesigns the shopping experience using Design Thinking.
  • An entrepreneur rebuilds a business idea using First Principles Thinking, then tests it with customers and gradually improves it using PDCA.
  • A team manager uses several frameworks together to address declining productivity instead of relying on a quick solution that may only treat the symptoms.
  • An engineer combines Root Cause Analysis, First Principles Thinking, and the PDCA Cycle to solve a complex technical problem sustainably.

- Conclusion:

No person can live their life without facing problems. Problems are a natural part of life, whether they are personal, professional, financial, social, or scientific. But what distinguishes successful people is not that they face fewer problems than others, but that they have a better way of dealing with them.

Problem-solving is not a talent that people are born with; it is a skill that can be learned, developed through practice, and strengthened through experience. The more a person learns how to analyze problems systematically, avoid hasty conclusions, and search for the real causes, the more capable they become of making sound decisions and achieving better results in different areas of life.

Throughout this article, we explored a number of the most important frameworks used worldwide for problem-solving, and we saw that each framework plays a different role, complementing the others rather than competing with them. Some help discover the real cause of a problem, some help generate solutions, and others focus on improving solutions or adapting to rapid changes.

- Summary of Problem-Solving Frameworks:

Framework Main Purpose Best Use
Plan, Do, Check, Act (PDCA Cycle). Continuous improvement. Developing processes and improving quality.
Root Cause Analysis. Discovering the source of the problem. Recurring problems.
5 Whys. Reaching the root cause. Simple and moderately complex problems.
First Principles Thinking. Creating new solutions. Complex problems and innovation.
Design Thinking. Designing human-centered solutions. Products, services, and user experience.
Observe, Orient, Decide, Act (OODA Loop). Making rapid decisions. Changing environments and crises.

- A Practical Map for Solving Any Problem:

Question Appropriate Framework
What is the problem? Define it accurately and gather information.
Why did it happen? Root Cause Analysis and 5 Whys.
How can a new solution be created? First Principles Thinking.

- Key Lessons to Remember:

  • Do not rush to treat symptoms before understanding the real cause.
  • Gather data before making a decision.
  • Do not assume that the traditional method is always the best.
  • Put human needs at the center of the solution when the problem is related to users.
  • Test solutions on a small scale before implementing them broadly.
  • Learn from the results and continuously improve your solutions.
  • Be prepared to change your decisions when the information changes.
  • Do not search for the perfect framework; search for the framework that best fits the problem you are facing.

Problem-solving is not simply about finding an answer; it is an organized process that begins with understanding the problem, then discovering its causes, designing the appropriate solution, testing it, and continuously improving it. The more thinking tools you develop, the more capable you become of dealing with challenges, making better decisions, and turning obstacles into opportunities for growth, learning, and success.
