ＰＳＰ（Personnel Software Process)

The Personal Software Process (PSP) shows engineers how to

• manage the quality of their projects
• make commitments they can meet
• improve estimating and planning
• reduce defects in their products

 

Because personnel costs constitute 70 percent of the cost of software development, the skills and work habits of engineers largely determine the results of the software development process.The PSP can be used by engineers as a guide to a disciplined and structured approach to developing software. The PSP is a prerequisite for an organization planning to introduce the TSP.

The PSP can be applied to many parts of the software development process, including

• small-program development
• requirement definition
• document writing
• systems tests
• systems maintenance
• enhancement of large software systems

Team Software Process (TSP)

What is TSP?

The Team Software Process (TSP), along with the Personal Software Process, helps the high-performance engineer to

• ensure quality software products
• create secure software products
• improve process management in an organization

 

Engineering groups use the TSP to apply integrated team concepts to the development of software-intensive systems. A four-day launch process walks teams and their managers through

• establishing goals
• defining team roles
• assessing risks
• producing a team plan

 

After the launch, the TSP provides a defined process framework for managing, tracking and reporting the team's progress.

Using TSP, an organization can build self-directed teams that plan and track their work, establish goals, and own their processes and plans. These can be pure software teams or integrated product teams of 3 to 20 engineers.

TSP will help your organization establish a mature and disciplined engineering practice that produces secure, reliable software. Find out how you can use TSP to strengthen your security practices.

TSP is also being used as the basis for a new measurement framework for software acquirers and developers. This effort is the Integrated Software Acquisition Metrics (ISAM) Project.
