The BOS-method architecture: An improved structured approach for the development of distributed information systems
A crucial point in all system development methods is the consistency problem of analysis at different abstraction levels. This point become even more important in the development of widely distributed information systems which needs to handle the feed back from technical details to the general distribution issues early in the analysis.
Although a structured methodology ([Yourdon 89]), by allowing the study at different levels of abstraction in parallel, is able to handle this feed back problem, it does not overcome the difficulty of managing and monitoring the development process. In order to solve this problem a rigorous life cycle model, structured in phases and stages, is needed. These two requirements appear to be contradictory.
This paper shows an improved structured methodology based on event-oriented modelling which harmonizes the parallel analysis on different levels of details with a life cycle based on phases and stages. It presents a methodology using a hierarchy of abstractions of models, which, although based on phases and stages, does not follow the idea of waterfall development
