The SEI helps advance software engineering principles and practices and serves as a national resource in software engineering, computer security, and process improvement. The SEI works closely with defense and government organizations, industry, and academia to continually improve software-intensive systems. Its core purpose is to help organizations improve their software engineering capabilities and develop or acquire the right software, defect free, within budget and on time, every time.
Please note that current and future CMMI research, training, and information has been transitioned to the CMMI Institute, a wholly-owned subsidiary of Carnegie Mellon University.
This presentation from SEPG North America 2011 by Jennifer Turgeon of Sandia National Laboratories presents a case study of using Scrum, RUP, and CMMI together, including implementation results, lessons learned, and recommendations.
