Discovering the cause behind the problem is a process of in-depth analysis and excavation, which requires the application of some specific methods and techniques. Here are some commonly used methods:
5Why Thinking Method:
This is a commonly used method, mainly by asking "why" continuously to get to the root of the problem. For example, when a problem occurs, start by asking "Why is this problem occurring?" Then in response to the answer, he continued to ask, "Why?" And so on until you find the root cause of the problem. This method is widely used in companies such as Toyota.
Root Cause Analysis (RCA):
This is a systematic approach to identifying the root cause of the problem. It typically includes the following steps: identifying possible causal factors, identifying root causes, identifying communication challenges, prioritizing communication challenges, ensuring that the root cause is within the team's sphere of influence.
Data Analysis & Trends**
Through the analysis of historical data, it is possible to discover the patterns and trends of problems, so as to improve the problems that may arise in the future. This approach often requires the use of statistical and data mining techniques.
Expert interviews and panel discussions:
Interviews with experts in the field, or group discussions, can lead to additional information and perspectives that can help uncover the root cause of the problem.
Experiments and simulations:
In some cases, the problem can be reproduced through experiments or simulations to gain a deeper understanding of the nature and causes of the problem.
When applying these methods, there are a few things to keep in mind:
Maintain an objective and impartial attitude and avoid subjective assumptions and emotions.
Gather as much information as possible, including the background of the problem, the context in which it occurred, and the perspectives of the people involved.
Don't settle for superficial explanations, dig deep into the root of the problem.
During the analysis, care should be taken to distinguish between cause and effect to avoid confusion.
Finally, it is necessary to develop effective measures to solve the root problem and prevent similar problems from happening again.
