What term is used for work required to achieve the completion of a deliverable?

The term "task" is used to refer to the work required to achieve the completion of a deliverable. In project management and methodologies like SAP Activate, a task is a specific piece of work or an activity that needs to be completed as part of a project. Tasks are often defined within a larger framework to ensure that all components of a deliverable are adequately addressed.

In the context of project planning, breaking down deliverables into smaller, manageable tasks helps teams track progress and assign responsibilities. By focusing on tasks, team members can clearly understand what needs to be done to achieve project goals, making the overall process more efficient.

While milestones represent key points or checkpoints in a project timeline, and activities are broader categories of work that encompass multiple tasks, they do not specifically refer to the individual pieces of work required to complete deliverables. Outputs are the final results produced by completing tasks, but they do not represent the work itself. Thus, "task" accurately captures the essence of the necessary work to achieve deliverables.
