The 5 Whys Application – Sakichi Toyoda

The relevance of 5-whys in achieving continuous improvement in the warehouse environment.

Sakichi Toyoda was born in Japan in 1865 and he is considered the founder of Japan’s industrial revolution. He invented the Toyoda loom, sold it to an English mill for 1 million Yen and used the money to start a new company named Toyota.

Toyoda once stated: “When you have a problem you should ask WHY 5 times to find the source of the problem and also prevent the problem from recurring”.

To try and solve a problem in the warehouse, sometimes by asking a simple “why” might not be enough, as it would not lead you to the bottom of the problem.

Most times one has to ask more than once “why”, in order to get a clearer understanding of the problem and move from the surface all the way down to the bottom of the problem.

Two required steps

  1. Write down the specific problem. Writing it down helps team focus on the same problem.
  2. Ask why the problem happens & write down the answer. Repeat it 5 times until team agrees  that problem is identified.

Let me give you a simple but tangible example taken from day-to-day activities in any warehouse environment:

A fork lift driver reports to his warehouse manager that his fork lift cannot start despite all his efforts.

A. SIMPLE ANALYSIS – 1 WHY.

The 1 why application: Problem – Answer – Response.

 

What about if the problem was not the battery but something else. You missed it, didn’t you?

A poor job of trying to identify the root cause of a problem will waste time & resources.

You are dressing up a wound after a fall without treating the wound first.

We shall need to identify the root of the problem as we shall need to understand that:

  • Mistakes happen as a result of workers’ “carelessness”,
  • Workers are not well trained to be more careful/attentive or they may lack motivation,
  • You and your team members may not have the time to go through all the way to the bottom of the problem,
  • Mistakes or errors are results of defects and the people (workers) are only part of the process,
  • We need to find out why it is happening and implement ways to ensure it would not happen again,
  • Fix it for good (once & for all) or the same problem may re-surface.

B. DETAILED ANALYSIS – 5 WHYS.

Now, let’s look at the same problem from a different perspective.

Asking the question ‘Why’ 5 times, will lead you to the root cause of the problem.

Let’s analyse the situation by applying the 5 whys:

5-Whys-300x164

 

Do you see the different approach?

Do you see how this 5-whys application could help the warehouse operation in achieving continuous improvement?

Do you see how the above example can help or improve your own business activities by dissecting the problem to its core elements until you arrive to the bottom of it?

Most importantly, it would prevent the same problem from surfacing again…
