This Department of Defense (DoD) Software Factbook provides an analysis of the most extensive collection of software engineering data owned and maintained by the DoD, the software resources data report (SRDR). The SRDR is the primary source of data on software projects and their performance. The Software Engineering Institute analyzed the SRDR data and translated it into information that is frequently sought-after across the DoD. Basic facts are provided about software projects, such as averages, ranges, and heuristics for requirements, size, effort, and duration. Factual, quantitatively derived statements provide easily digestible and usable benchmarks. Findings are also presented by system type or super domain. The analysis in this area focuses on identifying the most and least expensive projects and the best and worst projects within three super domains: real time, engineering, and automated information systems. It also provides insight into the differences between system domains and contains domain-specific heuristics. Finally, correlations are explored among requirements, size, duration, and effort and the strongest models for predicting change are described. The goal of this work was to determine how well the data could be used to answer common questions related to planning or replanning software projects. |
