T. Rowe Price Investment Technologies built The Product and Project Tracking System (PPT) to reduce the human resources needed to track and forecast Information Technology projects. Instead of developing or purchasing a new system, the need was met by integrating Commercial-off-the-Shelf (COTS) products already used and licensed by the company. The conclusion can be made that this approach reduces development costs while providing more flexibility than a single vendor solution. This paper described the process used and issues encountered in building a system from software products generally intended for stand-alone applications. It discusses the rationale behind the system, the choice of products, the software engineering process used, the handling of changes, and modifications made in business practice. A discussion will be made of the initial Return on Investment and ongoing support requirements.
