We're not really sure about IIPD. How does it fit in?

We're trying to reach CMMI ML3.  We don't understand how IPPD fits in.  Is it required?  Is it useful?

IPPD, or Integrated Process and Product Development,  is what is called an “Addition” in the CMMI model.  Unlike the rest of the Goals in ML3, which are required, the Goals in IPPD (two in IPM and two in OPD) are optional when you are trying to achieve ML3.

The Goals of IPPD provide guidance to better manage integrated teams, or teams that cross organizational boundries.  You may not feel you need the practices contained within it, and if that's the case, they are not required.

That said, I think IPPD is great and very useful and should be used to guide you in the way projects, teams, and organizations interact.

But, from a pure ML3 perspective, these Goals are optional.
