5 Whys is the practice of asking why repeatedly whenever a problem is encountered in order to get beyond the obvious symptoms to discover the root cause. For instance, Taiichi Ohno gives this example about a machine that stopped working (Ohno 1988, p. 17):What is the 5 why technique tool?
The 5 Whys strategy is a simple, effective tool for uncovering the root of a problem. You can use it in troubleshooting, problem-solving, and quality-improvement initiatives.

The 5 Whys Problem Solving technique is a simple process to follow to solve any problem by repeatedly asking the question “Why” (five times is a good rule of thumb), to peel away the layers of symptoms that can lead to the root cause of a problem. This strategy relates to the principle of systematic problem solving.What is 5 Why - A Root Cause Analysis Technique

The primary goal is to determine the root cause of a defect or a problem by successively asking the question “Why?”. The number '5' here comes from the anecdotal observation that five iterations of asking why is usually sufficient enough to reveal the root cause.What is the 5 why analysis framework?
The architect of the Toyota Production System, Taiichi Ohno, described the five whys method as "the basis of Toyota's scientific approach by repeating why five times the nature of the problem as well as its solution becomes clear." The tool has seen use beyond Toyota, and is now used within Kaizen, lean manufacturing, ...What is the 5 why technique useful for?
The 5 Whys Analysis can be used in practice by identifying the root cause of problems, implementing effective solutions to prevent recurrence, improving processes and systems, enhancing decision-making, fostering a culture of continuous improvement, and driving organisational success.What is the 5 Whys format?
The 5 Whys framework is a simple yet effective tool for problem-solving. The technique is based on the idea that by asking "why" five times in a row, one can uncover the root cause of a problem.

Asking why 5 times: “the 5 Whys”, is a simple but powerful tool to use with any problem solving activity. It's a technique to help you get past the symptoms of a problem, and to find its root causes. Simply ask the question “why” up to five times.What is the root cause of the problem?
The root cause is the core issue—the highest-level cause—that sets in motion the entire cause-and-effect reaction that ultimately leads to the problem(s). Root cause analysis (RCA) is defined as a collective term that describes a wide range of approaches, tools, and techniques used to uncover causes of problems.What are three key characteristics of 5 why analysis?
Keep discussion focused.Other considerations for conducting a root cause analysis with the Five Whys technique include the following: Distinguish root causes from their symptoms. Assess the process, rather than the people; human error should not be labeled the problem. Encourage focused and precise answers.
