This is one of the Rita's question:

 During activity definiton, the team discovers that they do no kno enough to define the activities for 30 percent of the work packages. What would be the best course of action

a) Redo Scope Definition

b) Continue on activity sequencing and define the activities at a later date.

Correct answer as per Rita is A. But as per roller wave planning or progress elaboration, answer should be B. Isn't it ?

Any thoughts?
