5. DETAILED REQUIREMENTS

The order of the requirements in this section is not intended to specify the order in which they must be carried out. Many of the activities may be ongoing at one time; different software products may proceed at different paces; and activities specified in early subsections may depend on input from activities in later subsections. If the software is developed in multiple builds, some activities may be performed in every build, others may be performed only in selected builds, and activities and software products may not be complete until several or all builds are accomplished. Figure 1 provides an example of how each activity may be applied in one or more builds. Non-mandatory notes throughout section 5 tell how to interpret each activity on a project involving multiple builds. A project involving a single build will accomplish all required activities in that build. Appendix G provides guidance for planning builds, determining which activities apply to each build, and scheduling these activities.
