摘要: The complex and dynamic environment in which information system development (ISD) is undertaken for today's business organisational clients has lead to a focus on Rapid Application Development evolutionary prototyping. However, such approaches only specifying the requirements technological support often fail appreciate actual problems faced by those involved within situation of focus. An interpretivist approach ISD places emphasis first creating shared appreciation reaching an accommodation concerning purposeful action that may be with hope bringing improvement. From this desirable feasible intervention, technology (IT) needed can specified, or changes existing legacy computing system, identified. aim UMISD project (a Unified Mechanism Information Systems Definition) develop practical ISD, developing modelling methods enable design process "Client-Led", as far possible, rather than directed toward fulfilling imposed engineering techniques.
