Which output includes a comprehensive list of activities for completing the project?

The correct answer is the Activity List because it specifically serves to provide a detailed compilation of all the activities necessary to successfully complete a project. This output is crucial in project management as it outlines the specific tasks and work items that need to be accomplished, allowing project managers and teams to have a clear understanding of what is required throughout the project lifecycle.

The Activity List contains descriptions of each activity, which can be essential for planning, organizing, and executing the project effectively. It ensures that no essential tasks are overlooked and facilitates the development of further project planning elements, such as the Project Schedule and activity dependencies.

In contrast, the Activity Attributes provide additional details about each activity listed, which can include information like resource requirements or constraints, but do not serve as a standalone comprehensive list themselves. The Milestone Lists highlight significant points or achievements within the project timeline rather than the activities needed for project completion. The Project Schedule, while critical for tracking progress and timelines, is derived from the Activity List and does not itself itemize all individual activities separately.
