d implementation issues, and the preliminary studies, simulation modeling, and prototyping required to resolve them. Implementation Characteristics The implementation characteristics that the software development plan should exhibit include measurement, procedures, and schedule. Measurement requires a set of indicators used to determine the success or failure of the technical aspects of the development process and the resulting design outputs. The plan should require data associated with the technical development of the design outputs to be collected and analyzed to determine software quality. The error rate found during the development phases should be measured, recorded, analyzed and reported. Procedures requires the division of each life cycle activity into well-defined tasks. The inputs to each activity and each task should be provided, and the sources of those inputs should be identified. The conditions that must be satisfied before each activity can begin should be described. The outputs from each activity and each task should be provided, and the destination of those outputs should be identified. The plan should include a review at the end of each life cycle activity. Reports on the technical development work should be described. Reg. Guide 1.173 describes acceptable methods for defining the inputs and outputs of the life cycle activities. Schedule requires a project schedule. The plan should identify key work packages, milestones and hold points. Sufficient intermediate milestones should be identified to avoid unexpected schedule delays. Reviews and audits should be included in the schedule as project milestones. The schedule should justify the time anticipated to complete each task. A single schedule that includes both management and technical activities is acceptable. Resource Characteristics Appendix 7-A Rev. 4 — June 1997 BTP HICB-14-13 The resource characteristics that the software development plan should exhibit include methods/tools and standards.
