Detailed design or low-level design determines the specific steps
required for each component or
process of a software system. Responsibility for detailed design may
belong to either the system
designers (as a continuation of preliminary design activities) or to the
system programmers.
Information needed to begin detailed design includes: the software
system requirements, the
system models, the data models, and previously determined functional
decompositions. The
specific design details developed during the detailed design period are
divided into three
categories: for the system as a whole (system specifics), for individual
processes within the
system (process specifics), and for the data within the system (data
specifics).
