Details:

Scope Baseline: The scope baseline consists of the project scope statement, work breakdown structure (WBS), and WBS dictionary. These documents provide a clear understanding of the project scope, which helps in identifying the activities required to accomplish the project objectives.

Project Scope Statement: This document outlines the project objectives, deliverables, constraints, and assumptions. It provides context for defining project activities.

Enterprise Environmental Factors: External factors such as market conditions, legal requirements, organizational culture, and infrastructure that influence project execution.

Organizational Process Assets: Lessons learned, historical information, and other organizational knowledge that can help in closing out the project effectively.

Decomposition: Decomposition involves breaking down the project deliverables into smaller, more manageable activities. It is usually performed iteratively, starting from the highest level of the WBS and drilling down to lower levels.

Rolling Wave Planning: In Rolling Wave Planning, activities for the near term are planned in detail, while activities for the future are planned at a higher level of abstraction. This allows for flexibility in planning and adapting to changing project requirements.

Expert Judgment: Seeking advice from experts to ensure that all closure activities are conducted effectively and efficiently.

Templates and Standards: Utilizing standardized templates and best practices for activity definition helps ensure consistency and efficiency in the process. These templates may include activity lists, activity attributes, and activity sequencing guidelines.

Activity List: The activity list is a comprehensive list of all the activities required to complete the project. Each activity is identified and described in detail.

Activity Attributes: Activity attributes provide additional information about each activity, such as activity codes, descriptions, predecessors, successors, resource requirements, and constraints.

Milestone List: Milestones are significant events or points in the project timeline. The milestone list identifies key milestones that mark the completion of major project deliverables or phases.

Change Requests: During the activity definition process, changes to the project scope or requirements may be identified. These changes are documented as change requests and undergo the change control process for evaluation and approval.
