What is typically modeled using a fragnet?

A fragnet is a specific construct within project scheduling used to represent a fragment or subset of a project's activities and dependencies. It is particularly useful for modeling changes or additions to an existing project schedule. The concept of a fragnet is most commonly applied when dealing with scenarios that involve inserted delay events, which are situations where disruptions or extensions to the project timeline occur.

Using a fragnet allows project managers and schedulers to visualize these delays or adjustments without affecting the entirety of the project schedule. It demonstrates how specific events or changes can impact the overall project duration and can help in analyzing how these delays interrelate with other activities. This modeling technique is essential for understanding the repercussions of delays and for effectively communicating these changes to stakeholders.

While resource allocation, overall project budget, and milestone achievement are significant aspects of project management, they do not specifically align with the primary function of a fragnet. Resource allocation focuses on optimizing the use of project resources, the overall project budget involves financial planning, and milestone achievement pertains to tracking key project deliverables. These elements may be discussed in different contexts but are not the primary focus of fragnet modeling.
