JahanSubject: Acquisition and Oversight of Contracted Software Development (1999) Abstract: The loss of MCO was attributed to, among other ca
2、uses, the lack of a controlled and effective process for acquisition of contractor-developed, mission critical software. NASA Centers should develop and implement acquisition plans for contractor-developed software and this should be described in each Project Implementation Plan. These plans must pr
