We Build High Performance Software Development Teams

Software's ChallengesSoftware organizations are under growing pressure to produce high-quality, reliable, and secure software products, but they must do so with fewer resources, lower costs, and predictable schedules. Yet the problems that have plagued the software industry for the past 50 years persist. Development and ownership costs continue to increase; delivery schedules are still unpredictable; and the defect count in software is still high, raising concerns about dependability and security1.
A Proven SolutionThe TSPSM, PSPSM and CMM® or CMMI® technologies were developed by the Software Engineering Institute (SEISM) of Carnegie Mellon University under a directive by the US Department of Defense. The SEI Software Process Technologies Watts Humphrey originally created the Capability Maturity Model® (CMM) which later became the SW-CMM® and the Capability Maturity Model Integrated® (CMMI) to help companies improve their software quality. After piloting CMM in several organization, Humphrey realized that the CMM concepts were not reaching the individual developer nor project teams of developers. He then created the Personal Software ProcessSM (PSP) and the Team Software ProcessSM (TSP) to address this need. TSP and PSP were designed from the onset to integrate with and extend CMM methodologies to lower organizational levels. To see how the TSP and PSP address the Key Process Areas (KPAs) of SW-CMM, see the SEI report, Relating the Team Software Process (TSP) to the Capability Maturity Model for Software (SW-CMM)2. The TSP and PSP best practices were released after extensive research with the data collected from dozens of field trials in industry. As of February 2004, there are 3,777 trained PSP software developers and 135 TSP-led projects conducted by the SEI and its Partners. The success of TSP is documented in in two SEI reports with the latest in The Team Software Process (TSP) in Practice: A Summary of Recent Results3.
TSP / PSP Benefits The proven success of the TSP and PSP technology has fostering its integration into over one hundred commercial, industrial and military organizations. These organizations have witnessed dramatic changes4 in:
These organizations realize that not only is quality free, but quality pays. Six-month TSP projects typically return the cost of their TSP/PSP training and support. In fact, organizations can recognized better than a 500% five-year ROI when institutionalizing TSP6. The figure below7 shows the defects/KLOC of delivered software by CMM Level compared to the TSP.
Defects/KLOC of Delivered Software Your organization can attain the same TSP benefits and software development cost reduction by starting with the on-site TSP Executive Strategy Seminar. This seminar, for software executives and middle managers, is a two-day process starting with an introductory course that covers the key concepts of the TSP and PSP from a management perspective. Afterwards, we have a round-table conference to create an introduction plan then discuss the costs and expected benefits and return on investment. Click here for the introduction strategy.
