Bandler founded OSA in 1983 to commercialize optimization methodology and algorithms which he and his colleagues had developed. OSA's first major project was the reengineering of key software for simulation and optimization of waveguide multiplexers for satellite communications under contract to
COM DEV International. In the 1980s OSA contributed optimization methodology and algorithms to EEsof’s early microwave CAD software Touchstone and Libra, and then reengineered
Compact Software’s principal software products SuperCompact and Microwave Harmonica. OSA implemented a yield-driven CAD and optimization capability for Raytheon Research Division in 1985. OSA was then subcontracted by Compact Software Inc. as part of the Raytheon/Texas Instruments Joint Venture MIMIC Program within the U.S. Department of Defense. Intended contributions included optimal design centering, enhanced circuit optimization with tolerances, and enhanced wafer/chip yield in a CAE environment. When
Hewlett-Packard Company (HP) acquired OSA in 1997, the company became part of HP
EEsof. Other users of OSA's technology included Siemens, Hughes Aircraft, TRW, Raytheon, Texas Instruments and British Telecom. ==Products==
