This lecture discuss the key concepts related to software process improvement. Triple constraint is the most important concern for project managers and software process infrastructure plays important role in successful project completion. The assessment of existing process based on the defined effective process may help in successful project completion. | Software Process Improvement SEII-Lecture 25 Dr. Muzafar Khan Assistant Professor Department of Computer Science CIIT, Islamabad. 1 Recap Software process improvement Framework for SPI SPI support groups, maturity and immaturity models Assessment and gap analysis Education and training Selection and justification Installation / migration Evaluation Risk management Critical success factors 2 CMMI Upgraded CMM as a complete framework Comprehensive process meta-model “continuous” model “staged” model Different process areas Project planning, requirements management etc. Each process area is defined in terms of specific goals and practices 3 CMMI Process Area Capability Profile 4 Figure source: Software Engineering: A Practitioner’s Approach, R.
