HKSM

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?

1. Define Activities
2. Sequence Activities
3. Estimate Activity Durations
4. 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.
