What defines a hammock activity in a project schedule?

A hammock activity is defined as an activity that spans several other activities within a project schedule and serves primarily for summarization or reporting purposes. This type of activity does not have a fixed duration or specific start and end dates that are predetermined, but rather its duration is dependent on the start and end dates of the activities that it encompasses. This makes hammock activities particularly useful for aggregating data and providing a higher-level overview of project performance or progress.

For instance, if multiple related tasks are being conducted, a hammock activity can be created to encapsulate these tasks and report on their overall status or impact within the project. It allows project managers and stakeholders to see how various segments of the project are interconnected and how time is being allocated across the project as a whole, facilitating better communication and decision-making.

An independent activity suggests that it stands alone without being tied to other processes, which contradicts the very nature of a hammock activity. Lastly, an activity that is regularly repeated throughout the project is typically referred to as a recurring activity, which again does not align with the summarization aspect that character
