  1. Introduction toThe Personal Software ProcessandThe Team Software Process Dr. Kaan Kurtel

  2. The Baseline Personal Process

  3. What Is a Process? • A process is the sequence of steps required to do a job. • The software process establishes the technical and management framework for applying methods, tools, and people to the software task. • The process definition; • Identifies roles, • specifies tasks, • establishes measures, • provides exit and entry criteria for the major steps. • As better methods are found, they can be incorporated into the process definition. • This helps all teams learn and it shows new teams how to take advantage of the experiences of their predecessors.

  4. The PSP0 Proces • PSP0 is a simple, defined, personal process. • Make a plan. • Use your current design and development methods to produce a small program. • Gather time and defect data on your work. • Prepare a summary report.

  5. Why Forms Are Helpful? • Determine what is to be done. • Decide how to do it. • Do it. • Check to make sure it is correct. • Fix any problems. • Deliver the final results.

  6. The PSP0 Process Elements Requirements Planning Development Design Code Compile Test Postmortem Finished product, Process data, Summary report

  11. PSP0 Postmortem Script • Watts S. Humphrey, “PSP: A Self-Improvement Process for Software Engineers”, Addison Wesley Professional, 2005.

  12. PSP0 Measures • PSP0 has two measures: • The time spent per phase • The defects found per phase

  13. Time Recording • Record the same basic data: • The project or program being worked on • The process phase for the task • The date and time you started and finished working on the task • Any interruption time • The net or delta time worked on the task • Comments

  14. The PSP0 Time Recording Log • Watts S. Humphrey, “PSP: A Self-Improvement Process for Software Engineers”, Addison Wesley Professional, 2005.

  15. Time Recording Log Instructions • Watts S. Humphrey, “PSP: A Self-Improvement Process for Software Engineers”, Addison Wesley Professional, 2005.
