5 WHYs: Positive Root Cause Analysis To Find Good Practices

In my earlier article I shared my opinion about using 5 WHYs to find root causes. What I really missed to point was, it is not just applied to find root cause to problems, but it can be used to find root cause to good things that are happening on the team.

In sprint retrospectives we usually pick some problem that occurred, try to figure out why it happened, and then understand how we could prevent this problem from happening again in the future. Our root cause analysis meetings are usually always on “What is That Not Going Well”.

Now let’s apply 5 WHYs thinking to this question…

5 Whys: Sprint Failed – Team Did Not Deliver Committed Work

Applying 5 Whys is a good way to address the problems that you are facing on your teams. This thinking is very simple, just ask WHY multiple times till you reach to root cause. You can read more about 5 Whys here.

Some benefits of using this Lean technique are:

Helps identify root cause of a problem
Determine the relationship between different root causes of a problem
Very simple to use without any statistical analysis
Very useful when problems involve human factors or interactions

Asking 5 times WHY generally leads you to a root cause. In some cases you may reach in fewer iterations and in some it may take more than 5.

Now let’s apply this technique to our problem on hand.

Problem: Team failed in their sprint as they were not able to complete all the work committed.
