Once the schedule management plan is prepared, the next step is to define the activities.

- When we start the project, we start with the high level scope, which gets elaborated into detailed scope.
- The detailed scope gets decomposed into Work Breakdown Structure (WBS)
- The work packages of the WBS gets decomposed further into activities
- For each activity, activity attributes like successor, predecessor, technical specifications, resource requirements, quality standards etc are defined
- Milestone list is prepared. Milestones are significant point or events in a project and do not have any duration by itself. When all the associated activities are completed, then the milestone is considered as achieved. A milestone list identifies all project milestones and indicates whether it is a mandatory contractual milestone or optional.
