In accordance with the PMBOK® Guide (Project Schedule Management), the process of Sequence Activities is specifically defined as the process of identifying and documenting relationships among the project activities. The primary purpose of this process is to define the logical sequence of work to obtain the greatest efficiency given all project constraints.

Every activity—except the first and last—should be connected to at least one predecessor and at least one successor with an appropriate logical relationship.

Key Inputs: Project Scope Statement, Activity List, and Activity Attributes.

Key Tools and Techniques: Precedence Diagramming Method (PDM), which is used to create a project schedule network diagram that uses boxes (nodes) to represent activities and connects them with arrows that show the dependencies.

Key Outputs: Project Schedule Network Diagrams, which are graphical representations of the logical relationships (dependencies) among the project schedule activities.

Analysis of Distractors:

A. Control Schedule: This is a monitoring and controlling process. It is the process of monitoring the status of the project to update the project schedule and manage changes to the schedule baseline.

C. Define Activities: This process involves identifying and documenting the specific actions to be performed to produce the project deliverables. It breaks down work packages into schedule activities but does not establish the links between them.

D. Develop Schedule: This is the process of analyzing activity sequences, durations, resource requirements, and schedule constraints to create the project schedule model for execution, monitoring, and controlling. Sequencing is a prerequisite for this process.
