The purposes of this study were to undertake an initial characterization of DoD mission critical software maintenance to identify policy issues and to outline the scope and major features of potential new or revised policy. We distinguished among three categories of mission related software. Within a category different organizations may use similar processes across categories they generally do not. For six specific types of software maintenance, we accounted for about 16,000 government and contract personnel equivalents 55 organic and 45 contractor maintaining 225M lines of code at an annual cost of about 1.26B. About 40 percent of the effort is corrective and 60 percent is a combination of adaptive and incremental improvement. Pure organic maintenance is the exception for any type of software organic maintenance of embedded software is generally found only on older models of weapon systems where attempted, competitive contract support proved both more economical and at least as effective as either sole source contract support or organic support. Written policy consists of MIL-STDs e.g., 2167 and 498 and local operating instructions rather than DoD instructions or Service regulations. There is a lack of consensus over what software maintenance is also depot maintenance.
