CMMI User Story #3: Did you experience a decrease in defects?

Welcome back to Ask the CMMI Appraiser for today’s installment of CMMI User Stories!

If you missed the previous posts about the new CMMI User Stories Report, we took a different approach to measuring the success of CMMI adoption. We asked: What do potential adopters and end-users really want to know? What perceptions do adopters, stakeholders, sponsors, shareholders, and customers have? What was their experience with the CMMI?

In the end, over 70 CMMI Users told us what they really think about the CMMI. Their stories are below.

Question #1: “Are projects more predictable with the CMMI?

Question #2: “Did you experience an increase in quality or performance?

Today we're highlighting Question #3:

Did you experience a decrease in defects?

The CMMI provides guidelines for deploying processes and improvements that lead to improving product quality and reducing defects. We wanted to understand whether organizations actually experienced these benefits through their adoption of the CMMI.

Over two-thirds of the respondents said yes, defects had decreased. Fewer than ten percent said, no, defects had not decreased. Twenty-two percent neither agreed nor disagreed. Surprisingly, the ambivalent response was selected three times more this year than in 2012.

Be sure to check back regularly as we share results of the CMMI User Story Report right here on Ask the CMMI Appraiser.

We’ve also made the information available in an eBook. If you would like to receive the complete set of user stories in the final Report, click here to access your free* copy.
