What is s curve in project management?

An S-curve in project management is a graphical representation of cumulative progress or cost over time. It is called “S-curve” because the graph typically resembles an “S” shape.

S-curves are used for cost management, resource allocation, and scheduling in construction, software, and manufacturing projects.

It helps in tracking project performance, analyzing resource usage, and predicting future progress. Initially, progress is slow, then accelerates, and finally slows as the project completes.
