This was the right thing to do, but it meant more effort and involvement and
decisions along the road for the leaders involved and the workers deeper in
the organization. They didn't like it, but eventually they reluctantly agreed.
Often the right answer requires more involvement of people and more decisions
along the way. 9
CAUTION
This approach to continuous planning requires collaboration, which takes
time and commitment. 10
6.31 CMMI Project Planning Consistent with Agile
Planning
The CMMI Project Planning (PP) Process Area provides an interesting insight
applicable to this effort. There exists a Specific Practice 1.4 in this process area
that says:
Determine estimates of effort and cost.
It doesn't say when you need to do this. Some argued that without the details
the plan was not complete. I argued the plan was accurate, and yes, there
would be more planning to come. The plan reflected how we would arrive at
those effort estimates. I wanted to describe in the plan exactly what we were
going to do and how we were going to do it. I didn't want to make up things
to make people feel we had more answers than we did.
LESSON 7
The CMMI doesn't require you to do things in a certain order or at a certain
time. It does expect you to say in your plan what you are going to do, and
then follow your plan. When the plan changes, update the plan. This is con-
sistent with both Agile concepts and the CMMI.
