Network Logic
The complete set of dependency relationships that link activities within a project schedule network diagram.
Key Points
- Represents all precedence ties among activities in the network diagram.
- Includes relationship types (FS, SS, FF, SF) plus any leads and lags.
- Drives sequencing, critical path, and total/free float calculations.
- Covers mandatory, discretionary, and external dependencies and must be kept current as the schedule evolves.
Example
In a software release project: A: Define requirements -> B: Design (FS); B: Design -> C: Develop (FS with 2-day lead to start early); C: Develop -> D: Test (SS with 3-day lag); D: Test -> E: Deploy (FF). Together, these ties form the project's network logic.

- Network Logic
- Resource Histogram
- Milestone List
Correct Answer: B — Network logic (the dependency ties among activities)
Explanation: Network logic is the collection of all activity dependencies in the schedule network diagram; the other options do not represent precedence relationships.
