What is a fragnet in the context of scheduling?

A fragnet, or "fragile network," refers to a small segment of the schedule that is created to represent a specific change or re-evaluation within a larger project schedule. This element can be used to analyze the impacts of proposed changes, such as additional tasks or modified dependencies, without altering the entire project plan.

The purpose of creating a fragnet is to facilitate focused discussions or assessments regarding the implications of potential amendments to the project. By isolating this part of the schedule, project managers can efficiently evaluate how adjustments will affect overall project timelines, resource allocations, and other connected tasks. This targeted approach allows for precise modeling of scenarios and aids in decision-making and risk management.

In contrast, components like a comprehensive project schedule involve all tasks and timelines without isolating specific changes, while analysis reports focus on the overall performance rather than specific adjustments. A tool for stakeholder communication, while important, does not encapsulate the technical and modeling function that fragnets provide in the context of scheduling.
