Master problem-solving with 5 Whys technique

Problem-solving is an essential skill necessary for survival in this current world. It is essential in balancing a daily routine and creating profitable businesses. However, problem-solving also has its secrets, and a practiced technique can turn even unsolvable challenges into practical solutions.

Constantly developing new strategies is necessary to become good at problem-solving. One of the techniques that have steadily proven to be highly effective is the “5Whys” technique. It is a straightforward but effective method of systematically identifying the root cause of any problem.

The 5-Whys technique is often employed in identifying the cause of defects in a process or system. It’s an effective tool because it helps identify why a problem happens, rather than merely addressing the symptoms of the problem, and helps provide a solution that eliminates the root cause of the problem.

What is the 5 Whys technique?

The 5 Whys approach is a means of discovering the root cause of issues through asking ‘why’ five times or as many times as needed until the root cause of the problem has been found. It is often associated with Toyota’s production system, sometimes referred to as Lean methods or Kaizen, although it has been practiced for decades by others. The 5 Whys approach helps to map an individual’s thinking process and decipher the effectiveness of their logic chain.

To apply the 5 Whys technique, one must start by clearly defining a problem or issue with the expectation of identifying the root cause(s). An analytical mindset is necessary, and one needs to be patient and passionate about identifying the source of the problem to obtain actionable insights.

The Five Why’s technique historically works by examining each effect or symptom of a problem with a simple question – “why?” Previous responses are used to ask the same question repeatedly, effectively digging into the root cause of the problem, which is usually hidden beneath the visible surface of the problem.

Why use the 5 Whys technique?

The 5 Why’s technique has its advantages, and its importance is evident in how it is being used by organizations and their employees. Some of its advantages include:

1. Helps identify root causes: Through repeating the “why” question, the 5 Whys technique helps to identify the underlying causes of a problem, rather than merely addressing the symptoms.
2. It’s extremely cost-effective: With 5 Whys, you do not need any sophisticated software. It is quick, straightforward, and easy to use, often requiring little or no investment.
3. Helps reduce risks: The root cause behind a problem is often the cause of future problems and risks, which by identifying and addressing it, will help prevent them from happening in the future.
4. It aids faster problem-solving: It is a logical sequence that does not require exclusive knowledge. The process is easy for all staff levels to utilize, making it an excellent way to quickly identify problems and find resolutions.
5. It’s a collaborative process: The process is an excellent team activity, promoting teamwork, encouragement, and better communication among employees, thereby, improving overall team performance.

How to Implement the 5Whys Technique:

Here are practical steps to use the 5 Whys technique to find a problem’s root cause:

1. Step 1: Define the Problem

The first step is to precisely define the problem that needs to be resolved. This should be a clear statement of the issue. For instance, if a company loses customers, the problem should state the number of customers, over what period, and how it affects the business.

2. Step 2: Create a Team

Assemble a team to carry out the 5 Whys process. The group should comprise personnel who have direct experience in the problem and those who are not directly involved.

3. Step 3: Ask ‘Why’ to the problem

Begin by asking, ‘why is this problem occurring?’ or ‘why did it happen?’ Then, the team will answer this question. The answer offered will prompt another ‘Why’ question to be asked.

4. Step 4: Dig Deeper

The team should ask and respond to the question “Why?” at least five times to discover the source of the issue. Setting a five-why limit is not a rule, and there are instances where asking ‘Why’ seven or eight times will yield more sustainable, actionable insights.

5. Step 5: Identify the Root Cause

The answer to the final “why” question, culminating in the revelation of the source of the problem, is typically the root cause of the issue and will yield a more permanent solution. Once the root cause has been discovered, solutions can be conjured.

6. Step 6: Implement the solution

Once you have selected the right solution, implement it. After the implementation has been completed, continue to test it until you are assured of its effectiveness.

Examples of Using the 5 Why’s Technique:

There are countless scenarios where the 5 Whys technique has been successfully applied. Here are some examples of the five-why method being utilized.

Example 1:

Let’s imagine a production company with a production flaw in some of their assembled pieces of equipment. The company could suffer the loss of more than $1.000.000 in profit if this issue is not resolved on time.

The 5 Whys process starts by drafting the problem, which is that the organization is returning defective products, ultimately causing a loss in the budget’s expense.

• Why is the company returning products? Because the assembled equipment is not working correctly.
• Why is the assembled equipment not working correctly? Because the parts did not fit correctly.
• Why did the parts not fit correctly? Because the machinery used to assemble the parts was not calibrated.
• Why is the equipment not calibrated? Because it was installed improperly and not working correctly.
• Why was it installed improperly? Because the installation tool was not available, or the specialist was not trained on how to correctly install the machinery.

The root cause (the hardware installation tool is not available or the specialist is not trained on how to effectively install machinery) of the defective assembled parts issue has been identified, and the solution could be repairing the calibration machinery and training the specialist or getting the installation tool to improve production efficiency.

Example 2:

A merchandise store that is experiencing some loss of revenue (returns) due to unhappy customers.

• Why are customers returning products? Because the products are not working correctly.
• Why are the products not working correctly? Because they did not understand how to use it.
• Why did they not understand how to use it? Because the product description was not explicit/detailed enough.
• Why was the product description not detailed? Because the copywriters did not acknowledge the products’ end functionalities.
• Why did the copywriters not acknowledge the end-users? Because they did not interact with the customers, or the quality control did not provide feedback to the copywriters.

The root cause of lost revenue is a disconnect between the quality control and the copywriting team, resulting in inadequate product descriptions. Implementing a solution will involve increasing interaction between the quality control team and the copywriting team to provide better product descriptions.

Final Thoughts:

In conclusion, the 5 Whys technique is cost-effective, helps identify the root causes of a problem, aids faster problem-solving, reduces risks, and is an excellent collaborative process. The 5 Whys technique emphasizes a recurring theme throughout the problem-solving process. For each answer given, the method is intended to ask why five times until no more insight can be gained.

Remember that patience and persistence to eliminate a problem should be encouraged when employing this technique. With the right mindset, your problem-solving skills will develop, and the 5 Whys technique will become one of your primary tools for identifying and eliminating issues, saving you time, money, and resources that you would have lost tackling non-starting solutions.

So, next time there is an issue, take a step back, investigate, and find the root cause using the 5 Whys technique. You would be surprised how quickly and effectively it yields solutions that offer long-term solutions.
