On the architecture and form of flexible process support

The ability of businesses to develop is frequently hampered by difficulties in changing underlying software systems. An example is the need to change when business partnerships are formed, or dissolved. This article is concerned with the architecture of business process support systems in the context of change, and particularly with the need for such systems to facilitate software change. The viable system model (VSM) is a cybernetic model of organisations that change. It provides an inclusive architecture in which both operational and development components are described within an organisation. This article illustrates, through a business supply chain example, the use of the VSM as an architecture for flexible process support systems. This architecture is systemic and inclusive: it incorporates the ongoing development of both the business and its underlying software. Copyright © 2006 John Wiley & Sons, Ltd.
