A new project has started, and the project schedule is being built. After the WBS is complete, scheduling of the activities begins. Which of the following is the most likely NEXT step?

Sequencing activities is the process of identifying and documenting the logical relationships among scheduled activities. After the WBS has decomposed deliverables into work packages and activities are defined, sequencing establishes predecessor-successor relationships and produces the project schedule network diagram, which is required before duration estimating or scheduling can proceed.

Resource allocation occurs later in schedule development, after activities have been defined and sequenced, because you must know the activity order and duration estimates before assigning resources effectively.

Setting the schedule baseline is one of the final steps in planning, done only after the full schedule is developed, compressed, and approved - not at the beginning of scheduling.

Determining tasks (Define Activities) is the step that precedes sequencing; since the question states the WBS is complete and scheduling has begun, activity definition is already done.
