The Five Why's of Finance (2024)

FAQs

What is 5 Whys in finance? ›

The “5 Whys” methodology is far and away one of the most efficient methods for honing in on and conceptualizing the root cause of any dilemma you might come across. This technique requires five iterations of asking “why” to probe continuously deeper into the root cause of an event. (“Why 5?” you might ask?

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.

The Five Whys strategy involves looking at any problem and drilling down by asking: "Why?" or "What caused this problem?" While you want clear and concise answers, you want to avoid answers that are too simple and overlook important details.

A common technique for root cause analysis is the “Five Whys.” This technique, credited to Sakichi Toyoda, the founder of Toyota Industries, involves asking why something happened and then why that happened and then why that happened, continuously exploring the cause-and-effect relationships underlying a particular ...

It's not useful to apply the same root cause analysis / problem-solving approaches for complex problems as you would simple problems. 5 Whys is not intended for complex problems; sophisticated, time-intensive causal analysis is not intended for simple problems.

The 5 Whys technique serves two primary purposes. First, it reveals the root cause of the problem, which helps organizations eliminate the cause and implement solutions that will prevent future occurrences. Second, the method encourages problem solving by bringing cross-functional teams together to address issues.

First, you look at a problem and ask why it happened. Once you answer the first question, you ask why that happened. Repeat this process five times in total and you will have typically found your true root cause.

The technique was originally developed by Sakichi Toyoda who stated that "by repeating why five times, the nature of the problem as well as its solution becomes clear." The five whys are used for drilling down into a problem and the five hows are used to develop the details of a solution to a problem.

It's just as it sounds: A discussion of the unexpected event or challenge that follows one train of thought to its logical conclusion by asking “Why?” five times to get to the root of what happened.

How to facilitate a 5 why? ›

Ask the group “why” that problem occurs or exists.

After each response, the facilitator again asks “why” concerning the last response up to 5 times. Teams should make every effort to confirm responses with data when possible. Five is just a guideline.

The 5-Whys is a simple brainstorming tool that can help teams identify the root cause(s) of a problem. Once a general problem has been recognized (either using the Fishbone Diagram or Process Mapping), ask “why” questions to drill down to the root causes.

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 does the 5 Whys mean? The Five Whys technique is the practice of asking five times why a problem or failure has occurred. By continually asking “why” and investigating the obstacle, the team uncovers the root cause(s) of the problem.

The 5 Whys technique involves asking why a problem occurred five times in succession. After each answer, you ask why again, digging into the next layer of the underlying cause. It's important to note that five is just a guideline—you may need to ask even more times.

The 5 Whys is a “root cause analysis” that aims to identify problems you're trying to solve, then drill down to their roots to solve them. The analysis is just what it sounds like—a series of five “Why?” questions.
