CA Harvest Software Change Manager (originally known as CCC/Harvest) is a software tool for the configuration management (revision control, SCM, etc.)
The first CCC (acronym for 'Change and Configuration Control') product was released in the early 70s and was designed as a project for a Defense Department contractor in Santa Barbara CA.
(The company at the time was Hughes Aircraft, now Santa Barbara Research Center for Raytheon.)
CCC was designed to manage all the components that went into an aircraft engine, and seeing as the same engine was used by both the U.S. Air Force and U.S. Navy (for the F-14 Tomcat and F-15 Eagle) it required robust and reliable parallel development.
The first version of CCC/Harvest was commercially developed by Softool Corporation, a CM-focused software company founded in 1977 in Goleta, CA.
