Is CAR applicable to the project or the organization?

Should CAR be applicable only at the organization level and not at the individual project level? I ask this question since CAR is towards resolving common causes which is coming from the QPM, OPP outputs.

The CMMI specifically assigns usage of CAR to the projects, and then tells us it COULD be an input into OID, the organizational PA used to identify and implement improvements.  CAR can address problems at the project level, and can be an input into OID ("Collect Improvement Proposals")

On the other hand, if the "problem" you're trying to fix is an organizational problem, such as say, the process not working, then there is no reason CAR couldn't be applied to the "process project."
