ABSTRACT
Design and Development is the responsibility of the System Developer, although system users often take a leading role in the Design Review. The activities associated with this phase vary between projects, but generally follow the established pattern of Supplier Project/Quality Plans, Functional Specification, Software and Hardware Design, and Design Review. Facilitating requirement traceability is one of the most important activities. Throughout Design and Development, project managers should beware of extensions to the scope of the URS (sometime referred to as the “scope creep”). This is because each modification is likely to lead to a revision to the Functional Specification and subsequent documents, with associated incurred costs and project delays. If such extensions are still occurring by the time coding has commenced, and the supplier’s development capability is not up to managing this safely, final software quality may be seriously degraded.
