  • It’s the process of defining and documenting the specific actions to be performed to produce the project deliverables .
  • This process involves taking the work packages produced in create WBS process and decomposing them into activities that are required to produce the work package deliverables.
  • Activities produced are more related to actual project work that will produce project deliverables.
  • Activity Types :
  1. Level of efforts, Support and measured in time period.
  2. Discrete efforts, indirect proportion to other activities.
  • Note for the exam that if the team is decomposing project deliverables, they are in creating WBS process, if they are decomposing work packages, they are in define activities process.
  • This process can be combined with Create WBS; it depends on the project manager.
  • Rolling Wave planning is the major tool here in addition to the decomposition , it is used when the project contains a lot of unknowns , it is about planning at a higher level and then wait until the project work has begun and the work is clearer to plan lower levels , it is called “ progressive elaboration “ also .
  • This process results in Activity list, activity attributes and Project milestones.
  • The activity list includes the schedule activities required on the project .
  • The activity attributes extend the descriptions of the activity by identifying multiple components associated with each activity .
  • Milestones: significant events within project schedule , they have no durations, project milestones may be mentioned in project charter , they can be used as check points to help control the project.
