PMP Q #43- Recurring Defects
Q43. Your team is in the mid of the 7th iteration, and you observe a recurring trend for a particular type of defect. These defects are creating rework in the current iteration.
A. Root cause analysis on these defects.
B. Start discussing defects in daily stand-ups.
C. Reserve some time in retrospective for doing root cause analysis.
D. Reserve some capacity for rework in the next iteration.
Option A – “Root cause analysis on these defects” – is best when you have a recurring trend of getting defects that create rework.
The question clearly shows that you are in the mid of the 7th iteration, and delaying it for the next retrospective or iteration, which has a current impact, may not be a good idea. The rework is getting generated in the current iteration. It is a trend, but it is also a trend in the current iteration. You can wait if the impact is not on the current iteration.
So options C and D are not suitable to solve this problem.
Also, discussing during Daily Stand up is not enough because the team need to discover the fundamental reason for these recurring defects – this discovery can come only using root cause analysis. So rather than discussing the defects during Daily Stand-up, better team allocate some time after the daily stand-up and do a root cause analysis on it and find out what they should do differently in the current iteration. So that they can minimise or avoid rework. Daily Stand up is not the ideal place to do root cause analysis; it is mainly to see what work the team should do in the next 24 hours, which can contribute to the iteration goal. So option B also ruled out to solve this problem.
