An Approach to Integrating Soft Systems Methodology and Object Oriented Software Development

Abstract

The key aim of the research discussed in this paper has been to investigate ways of integrating techniques from SSM (Soft Systems Methodology) into the requirements elicitation stage of an agile system development method based on the UML (Unified Modelling Language). We argue that used alone UML models can encourage early design decisions before opportunities for improvement have been agreed and that SSM lacks the detailed information required by programmers. This leads to the conclusion that there could be some advantage in using the techniques together. In developing an integrated method we have been influenced by the recent trend towards agile systems development. This represents a move away from seeing software development methods as codified practices focusing on specific artefacts within a prescribed lifecycle. Instead emphasis is placed on the provision of a framework of development activities, products and workflows together with guidance for applying these to a particular application area. The design of the research is as follows: 1. An Information Systems Development (ISD) project is being carried out using SSM and UML techniques to make recommendations about the design of our School’s intranet. This is being written up as a case study. 2. The case study is being used to reflect upon and develop a hybrid method (or development framework) and a supporting CASE (Computer Assisted Software Engineering) tool. 2 The discussion of how the proposed framework emerged from our practical experience is punctuated with UML and other types of model that relate to the design of the supporting CASE tool
