David E. Bellagio has been involved in software development for the last 25 years, ever since he got addicted to it in high school. After realizing that he would not be a professional baseball player, he went on to receive his Bachelor of Science and Master of Science degrees in computer science, with honors, from Chico State University, California. David worked previously at CSC, Tandem Computers, ADP, and HP. He first began using ClearCase in 1994, and he spent the next four years deploying ClearCase to many developers while employed at ADP and HP. In 1998, he joined Rational Software as a technical field representative in the Pacific Northwest.

David currently is a Worldwide Community of Practice Leader for Enterprise Change Management at IBM, Rational Software. He works with customers and IBM teams to ensure successful deployment and adoption of Rational SCM solutions. David works with Rational field teams delivering workshops, seminars, and assessments to help improve software process and customer results. He also works onsite with customers around the world to define and manage successful deployment of Rational Software solutions.
