After defining activities in project schedule management, which processes should a project manager follow?

Per PMBOK's Project Schedule Management knowledge area, the process sequence is: Plan Schedule Management, Define Activities, Sequence Activities, Estimate Activity Durations, Develop Schedule, and Control Schedule. Sequencing must occur before estimating durations because the activity relationships and dependencies identified in sequencing inform how durations are estimated and constrained. Skipping or reordering these steps would result in an inaccurate or incomplete schedule model.

Estimate Activity Durations and Control Schedule skips the required Sequence Activities step and jumps directly to controlling, bypassing the Develop Schedule process entirely.

Develop Schedule and Control Schedule are later processes in the sequence and cannot occur before activities have been sequenced and their durations estimated.

'Review Activities' is not a recognized PMBOK process in the Schedule Management knowledge area, making this option invalid.
