Activity Definition

Activity Definition
– Identifying and documenting the specific activities that
must be performed to produce the various project
derivables and subderivables identified in the WBS


Inputs to Activity Definition
1. Work Breakdown structure
2. Scope statement
3. Historical information
4. Constrants
5. Assumptions
6. Expert judgment
Tools and Techniques for Activity Definition
1. Decomposition
2. Templates
Activity Definition (cont.)

Outputs from Activity Definition
1. Activity list
2. Supporting detail
3. Work breakdown structure update
Activity Sequencing

Definition
– Identifying and documenting interactivity logical
relationships.


Inputs to Activity Sequencing
1. Activity list
2. Product description
3. Mandatory dependencies
4. Discretionary dependencies
5. External dependencies
6. Milestones
Tools and Techniques for Activity Sequencing
1. Precedence diagramming method (PDM) (fig 6-2)
2. Arrow diagramming method (ADM) (fig 6-3)
3. Conditional diagramming methods
4. Network templates
Activity Sequencing (cont.)

Outputs from Activity Sequencing
1. Project network diagrams (fig 6-2 and fig 6-3)
2. Activity list updates
Activity Duration Estimating

Definition
– Taking information on the project scope and
resources and then developing durations for input to
schedules

Inputs to Activity Duration Estimating
