Susan Harker, Ken Eason, John E. Dobson · 2002
The difficulty of handling changing requirements within traditional development processes is described. The origins of changing user and organizational requirements are discussed and different types are classified. The author identifies a number of ways in which different approaches to design may help to deal with change as well as mechanisms which should underpin effective communication between users and designers.>
