Complete Methods for Building Complete Applications

摘要

nformation systems development methods (ISDMs) produce a product, the application, by following a development process model. We argue that in failing to produce the application process model that supports the application product, ISDMs only address part of the IS development problem. Additionally, we show that there is, in fact, a range of abstractions of the application product and process and ISDMs do not build these abstractions.. To address these issues, we define the completeness principle that integrates the 100% and conceptualization principles of conceptual modelling. This principle states that an information system should be a faithful representation of the product and process models at the required level of conceptualization. A method that complies with this principle is called a complete method. We develop a complete method and discuss issues raised in developing such methods.
