PSPO Process Script

Phase Number	Purpose	To guide you in developing module-level programs
	Inputs Required	Problem description PSPO Project Plan Summary form Time and Defect Recording Logs Defect Type Standard Stop watch (optional)
1	Planning	Produce or obtain a requirements statement Estimate the required development time Enter the plan data in the Project Plan Summary form Complete the Time Recording Log
2	Development	Design the program Implement the design Compile the program and fix and log all defects found Test the program and fix and log all defects found Complete the Time Recording Log
3	Postmortem	Complete the Project Plan Summary form with actual time, defect, and size data
	Exit Criteria	A thoroughly tested program Completed Project Plan Summary with estimated and actual data Completed Defect and Time Recording Logs

PSPO Planning Script

Phase Number	Purpose	To guide the PSP planning process
	Entry Criteria	Problem description Project Plan Summary form Time Recording Log
1	Program Requirements	Produce or obtain a requirements statement for the program Ensure the requirements statement is clear and unambiguous Resolve any questions
2	Estimate Resources	Make your best estimate of the time required to develop this program
	Exit Criteria	A documented requirements statement A completed Project Plan Summary with estimated development time data Completed Time Recording Log

PSPO Postmortem Script

Phase Number	Purpose	To guide the PSP postmortem process
	Entry Criteria	Problem description and requirements statement Project Plan Summary with planned development time Completed Time Recording Log Completed Defect Recording Log A tested and running program
1	Defects Injected	Determine from the Defect Recording Log the number of defects injected in each PSPO phase Enter this number under Defects Injected--Actual on the Project Plan Summary
2	Defects Removed	Determine from the Defect Recording Log the number of defects removed in each PSPO phase Enter this number under Defects Removed--Actual on the Project Plan Summary
3	Time	Review the completed Time Recording Log Enter the total time spent in each PSPO phase under Actual on the Project Plan Summary form
	Exit Criteria	A fully tested program Completed Project Plan Summary form Completed Defect and Time Recording Logs

PSPO Development Script

Phase Number	Purpose	To guide the development of small programs
	Entry Criteria	Requirements statement Project Plan Summary with planned development time Time and Defect Recording Logs Defect Type Standard
1	Design	Review the requirements and produce a design to meet them Record time in Time Recording Log
2	Code	Implement the design Record in the Defect Recording Log any requirements or design defects found Record time in Time Recording Log
3	Compile	Compile the program until error free Fix all defects found Record defects in Defect Recording Log Record time in Time Recording Log
4	Test	Test until all tests run without error Fix all defects found Record defects in Defect Recording Log Record time in Time Recording Log
	Exit Criteria	A thoroughly tested program Completed Defect Recording Log Completed Time Recording Log
