Concluding Remarks

We began this article with a brief description of the interaction of technology with business which is driving continuous change in the marketplace.  This provided a motivation to understand this interaction on a conceptual level.

We have created a business concept architecture, drawing on some models from general systems theory and on a cognitive architecture of the human brain.  This is a companion piece to similar work that has explored the concepts relevant to understanding architectures of IT systems.  Our conceptual architecture tries to understand the sources of requirements imposed on business systems, and the key areas of interest in the business system itself.

We have discussed various methods of extending and refining business patterns, via a more detailed set of business models produced by a work product based methodology.  This is an approach to handling the continuum from commonality to variability that is a significant challenge for leveraging investments in information systems technology.

Finally, we have mapped business concepts to information technology concepts.  Throughout this discussion we have maintained a focus on how this business conceptual architecture can help drive the content understanding for the IT system, and partition the work of building it.

This article lays the groundwork for additional work in subsequent phases of ESS in the area of articulating variations on the business architectural concepts and relating them to the set of IT system architectures at a more detailed level.
