5 whys quickly getting to the root of a problem

The 5 Whys is a simple problem-solving technique that helps users to get to the root of the problem quickly. made popular in the 1970 s by the Toyota Production System, the 5 whys strategy involves looking at any problem and asking: "Why? "And" what caused this problem? "

 

Following is an example of the 5 Whys Analysis as an effective tive problem-solving technique:

 

Why is our client, Hinson Corp., unhappy? Because we did not deliver our services when we said we wowould.

 

Why were we unable to meet the agreed-upon timeline or schedule for delivery? The job took much longer than we thought it wocould.

Why did it take so much longer? Because we underestimated the complexity of the job.

Why did we underestimate the complexity of the job? Because we made a quick estimate of the time needed to complete it, and did not list the individual stages needed to complete the project.

Why didn't we do this? Because we were running behind on other projects. We clearly need to review our time estimation and specification procedures.

Key points:

The 5 whys strategy is an easy and often-valid tive tool for uncovering the root of a problem. because it is so elementary in nature, it can be adapted quickly and applied to most any problem. bear in mind, however, that if it doesn' t prompt an intuitive answer, other problem-solving techniques may need to be applied.
