===Evolutionary systems development===
[[Evolutionary Systems]] Development is a class of methodologies that attempt to formally implement evolutionary prototyping. One particular type, called [[Systemscraft]] is described by John Crinnion in his book ''Evolutionary Systems Development''.

Systemscraft was designed as a 'prototype' methodology that should be modified and adapted to fit the specific environment in which it was implemented.

:Systemscraft was not designed as a rigid 'cookbook' approach to the development process. It is now generally recognised[sic] that a good methodology should be flexible enough to be adjustable to suit all kinds of environment and situation...<ref name=Crinnion1991p18/>

The basis of Systemscraft, not unlike evolutionary prototyping, is to create a working system from the initial requirements and build upon it in a series of revisions. Systemscraft places heavy emphasis on traditional analysis being used throughout the development of the system.
