Roger R. Bate - Software Engineering Institute

Software Engineering Institute

After retiring from Texas Instruments in 1991, he continued his interest in integrated systems development by joining the Software Engineering Institute. While at SEI, General Bate was the Chief Architect of the Capability Maturity Model Integration suite of products. Bate was a fellow of the Association for Computing Machinery (ACM), a fellow of the Society for Design and Process Science, and a Texas Instruments Fellow.

His work at the SEI included the initiation of the Systems Engineering Capability Maturity Model (SE-CMM). As Bate was working on the SE-CMM, other Capability Maturity Models were beginning to grow and Bate was asked to chair a group charged with evaluating the idea of integrating the CMMs in 1994. This work led to the Capability Maturity Model Integration (CMMI).

The culmination of Bate’s work at the SEI came around the release of CMMI for Development (CMMI-Dev) V. 1.2. The CMMI Steering Group decided that a new architecture would help CMMI expand its coverage and extend into other domains. The revised version employs a new architecture and a new term—constellations—to describe how components are grouped.

With Bate’s help, the SEI was able to greatly expand and enhance the improvement opportunities available to the U.S. defense community and to the worldwide development community through CMMI.
