During the planning phase, a scheduler uses a WBS as a reference to create a list of activities. The next step of the process is to provide a sequence for all the activities. With which of the…

The WBS dictionary provides detailed definitions and attributes for each WBS element and is used as an input to activity definition, not as the result of sequencing activities.

A project timeline is a high-level summary representation of the schedule and is produced after activity sequencing and duration estimating have already been completed.

A network diagram, typically built using the Precedence Diagramming Method (PDM), maps the logical sequence and dependency relationships between all project activities identified from the WBS. It is the direct output of the Sequence Activities process in project schedule management and must be completed before duration estimates and schedule baselines can be finalized. The network diagram enables critical path analysis and forms the structural foundation for the project schedule.

A Gantt chart is a time-phased bar chart used to display the finalized project schedule and can only be created after activity sequencing and duration estimation are complete.
