CALS began in 1985 as a way to reduce the paperwork and coordination efforts involved in the procurement functions associated with the design, development, and maintenance of large weapons and aerospace systems in the U.S. Under sponsorship of the U.S. Department of Defence (DoD), a process was established whereby standards were developed and implemented to support electronic sharing of information among the DoD and its prime and subcontractors. At that time, the acronym for CALS stood for Computer Aided Logistic Support. In 1987 and 1993, as the scope of CALS expanded, the acronym became known as Computer aided Acquisition and Logistic Support and then Continuous Acquisition and Lifecycle Support.
