NASA PERT and Companion Cost System Handbook, Director of Management Reports, NASA, 1962

At present, the Lockheed-originated 7090 computer program or one of the three variations it originated by the Langley Research Center, the Manned Spacecraft Center or the Hughes Aircraft Company are being used within NASA. The Langley Research Center and Manned Spacecraft Center variations are being merged into a single program which will become a standard NASA-PERT (time) program. This program will then be extended into a standard NASA-PERT and Companion Cost System program. For purposes of illustrating the discussion contained in the following sections the NASA-PERT Fragnet shown [at right] was computer-processed by the Manned Spacecraft Center.
