1. Are distinct from both project & product scope.
2. Include work to ensure that the product scope is achieved.

Project scope is WBS Baseline, and WBS baseline includes project management activity, thats the 100% rule.
So I would not agree with RIta.

What is the explanation provided by Rita?

[Jahiru_Q]

Project management activities include work to ensure that the product scope is achieved.
