Sequence Activities
The process of determining and recording how project activities are logically connected and depend on one another.
Key Points
- Defines logical links among tasks (FS, SS, FF, SF) and applies leads and lags where appropriate.
- Typically uses the Precedence Diagramming Method (PDM) to create a schedule network diagram.
- Considers dependency types: mandatory, discretionary, external, and internal, along with constraints and assumptions.
- Performed after activities are identified and before estimating durations and developing the full schedule.
Example
A project manager maps the sequence: Complete Design (FS) Build Prototype (FS with a 2-day lead for early procurement) Test Prototype (FS with a 1-day lag) Deploy. The resulting network diagram shows all relationships, including the lead that allows procurement to begin slightly before design finishes.
PMP Example Question
While creating a network diagram, you add a 3-day lag between "Pour concrete" and "Remove forms." Which process are you performing?
- Define Activities
- Sequence Activities
- Estimate Activity Durations
- Control Schedule
Correct Answer: B — Sequence Activities
Explanation: Adding lags and defining how tasks relate (dependencies) is part of sequencing activities, not identifying activities, estimating durations, or controlling the schedule.
