What Is the S-Curve in Project Management?
Project management is a complex process that requires careful planning, execution, and monitoring. One of the measurement tools used by project managers to track progress and performance is the S-curve.
An S-curve is a visual tool that allows project managers to identify trends and make data-driven decisions to ensure projects stay on track. In this article, we will explore what the S-curve is, how it works, and why it is such a valuable tool for project management.

The definition of the S-curve
In project management, an S-curve is a mathematical graph that depicts relevant cumulative data for a project — such as cost or man-hours — plotted against time. The reason it’s called an S-curve is because the shape of the graph typically forms a loose, shallow “S.” (The shape, however, depends on the type of project, so other formations are possible.)
An S-curve in project management is typically used to track the progress of a project. In today’s fast-paced business climate, ensuring that a project is on schedule and on budget is paramount to its success.

Why an “S”?
The S-curve often forms its shape because the growth of the project in the beginning stages is usually slow. The wheels are just beginning to turn; team members are either researching the industry or just starting to engage in the first phase of execution, which can be slow before working out the kinks.
As more progress is made, the growth accelerates rapidly—creating that upward slope that forms the middle part of the “s.” This point of maximum growth is called the point of inflection. During this period, project team members are working heavily on the project, and many of the major costs are incurred. After the point of inflection, the growth begins to plateau, forming the upper part of the “s” known as the upper asymptote—and the “mature” phase of the project. This is because the project is mostly finished at this point and is winding down — typically only tasks such as finishing touches and final approvals are left at this point.
Common uses for the S-curve in project management
Some of the most common uses for S-curves are to measure progress, evaluate performance and make cash-flow forecasts.
An S-curve is helpful in monitoring the success of a project because real-time cumulative data of various project elements —such as cost—can be compared with projected data. The degree of alignment between the two graphs reveals the progress—or lack thereof—of whichever element is being studied. If corrections need to be made to get back on track, the S-curve can help identify them.
Track your project progress with Wrike
In conclusion, the S-curve is a powerful tool in project management that provides insights into the project’s progress, performance, and potential risks. By monitoring the S-curve, project managers can identify areas that require attention, assess the project’s overall health, and make data-driven decisions to keep it on track.
Using Wrike, you can also leverage other features to visualize project timelines and track progress, including Gantt charts and automated reports. By streamlining all of your work in one platform, you can keep a close eye on your project and catch any issues before they escalate.
