For the past 15 years, multiple teams at Vencore had been conducting separate and successful CMMI-DEV ML3 appraisals. Each group had its own processes, Quality Management (QM) teams and LAs. Due to multiple organizational changes, the decision was made to bring both QM groups and the scope of their CMMI appraisals together into one unit. The integration of the groups is a process which has taken two years and is still ongoing. The presentation will discuss the massive effort needed to unite these two distinct groups, each with their own histories and cultures, into one organization which successfully achieved a CMMI Level 3 rating. It will review the victories & challenges overcome.
