Skill Center Manager of the 133-person Software Engineering and Applications Software Skill Center from April 1990 to April 1991. Responsible for over $24M of software programs, both contract work and internally funded R&D.

- Managed the Human Machine Interface (HMI) Systems Department from April 1987 to April 1990, growing the organization from 38 persons to 73 technically superior software engineers, before being merged into the larger Skill Center. As part of the role of the leader of the HMI Department, became self-taught on the products and technology, later growing to be a recognized expert related to software engineering and HMI.

- Developed 360-degree personnel evaluation process. Supported numerous in-house corporate activities including Affirmative Action Sub-Committee Chair, TRW representative at TRW Foundation presentations, and communications videos. 

- Formerly Software manager for C programming task on Sun/VAX network communications systems running UNIX/ULTRIX. Performed as Systems Analyst for a number of software activities, with full life-cycle perspective for software development. Performed requirements definition and system operator task analysis, software and database architecture design, computer simulation, performance analysis, software development, test, and documentation.
