6.3 Sequence Activities:
What is it?
- Process of converting project activities from a list to a logical sequence.
Why?
- Logical relationships form the basis for creating a realistic project schedule, considering all constraints.
-
How?
- Determine dependencies between activities.
- Sequence activities using appropriate diagramming techniques.
- Apply leads and lags if necessary to create a realistic and achievable schedule.
Dependency:
- Dependencies within the project's control.
- Example: Project schedule is rushed, but the engineering team hasn’t finished the engine design.
- Dependencies outside of the project's control.
- Example: Deliverable of another project or decisions made by a committee, lawsuit, or new law.
- Legally, contractually required, or inherent in the nature of work.
-
- Example: You can’t build your house until the foundation is in place.
- Discretionary Dependencies
- Preferred order of activities, defined by the project management team based on best practices.
- Known as soft logic, preferred logic, or preferential logic.
- Example: Painting the walls before carpeting the floors.
-
Leads and Lags:
- Lead: Time that a successor activity can start before its predecessor is complete.
- Example: Landscaping starts 2 weeks before the punch list completion.
- Lag: Waiting time that a successor activity must wait after the predecessor is complete.
- Example: Construction starts 3 days after the foundation is finished.
