Editing Software design (section)

== Value ==

[[Software design document]]ation may be reviewed or presented to allow constraints, specifications and even requirements to be adjusted prior to [[computer programming|coding]]. Redesign may occur after a review of a programmed [[simulation]] or [[prototype]]. It is possible to design software in the process of coding, without a plan or requirement analysis,<ref>Ralph, P., and Wand, Y. A Proposal for a Formal Definition of the Design Concept. In, Lyytinen, K., Loucopoulos, P., Mylopoulos, J., and Robinson, W., (eds.), Design Requirements Engineering: A Ten-Year Perspective: Springer-Verlag, 2009, pp. 103-136</ref> but for more complex projects this is less feasible. A separate design prior to coding allows for [[multidisciplinary]] designers and [[subject-matter expert]]s (SMEs) to collaborate with programmers in order to produce software that is useful and technically sound.
