Time Mgmt question

 In Estimate Activity Durations process, which of the following is not an assumption?

  Choice 1  Existing conditions 
  Choice 2  Availability of information 
  Choice 3  Length of the reporting periods 
  Choice 4  Project scope 


Please also briefly explain.


Thank you all.

'Project Scope' is not an assumption.  Scope is defined and WBS is already developed b4 Time Management activities get started.



I believe the correct answer to be 4. There can be assumptions in project scope, but project scope can't entirely be an assumption. Also, Define Scope process should have been completed before Estimate Activity Durations.

Whole Project Scop can not be assumptions.
