S-curves can be an incredibly powerful tool in the management of projects. They graphically display cumulative progress information over time and can be used to gain valuable insight into any type of project. The curves provide an intuitive method for the project team and stakeholders to understand how a project is progressing.
AACE International created a Recommended Practice (RP 55R-09) that outlines the use of S-curves in project controls. Within this Recommended Practice, there are three primary types of S-curves outlined:
- earned value
These curves typically have a time-period that reflects the reporting period for the project (often monthly), but a more detailed weekly or even daily timescale may be useful in specific projects. Two other types of curves are described by the RP including quantity produced and cash flow curves.
ARES PRISM is able to create all of these curves and more following suggested best practices. By creating a graphic representation of vital information, managers are able to quickly grasp the status of a project and recognizing when things are moving in a negative direction. These S-curves can be viewed in dashboards or produced in PRISM reports for management to review.
We have created a white paper that outlines the AACE Recommended Practice 55R-09 and describes the various S-curves that can be used in the management of projects. The white paper also shows the creation of S-curves in ARES PRISM and the benefits it provides.
