This paper consolidates the functional and data flow requirements of a quantitative maintainability program and contrasts these requirements against existent DOD maintainability specifications. An analysis is made of the results so far achieved in the field of maintainability and indicates the number of projects which have quantitative maintainability requirements.
In conclusion, the paper suggests the establishment of a data bank for the recording and exchanging of critical maintainability data so that maintainability programs can be implemented effectively.
