Roger Sessions Abstract

Topic: The Anti-Complexity Patent

Some recent news is of special interest to the Enterprise Architectural Community. For the first time ever, the United States Patent and Trademark Office has issued a patent for an EA methodology that promises to reduce the complexity of large IT systems.

This patent plays particularly well with capability oriented approaches to EA. Capability orientation is important because of its ability to understand the enterprise in natural byte sized pieces called capabilities and map business dependencies through capability maps. These capability maps can then be used to drive a service-oriented architecture that closely follows the needs and organization of the business.

However today’s methodologies for capability maps all suffer from a serious flaw. They are created through a process of decomposition. For a given enterprise, the number of possible decompositions (that is, capability maps) is given by Bell’s Number, which, for most enterprises, is astronomically high.  The chances that any current approach to decompositional analysis will happen to find the best possible decomposition (i.e. capability map) are virtually nill.

This patent solves this problem by introducing a new way of creating capability maps: through synergistic analysis. Synergistic analysis is different from decompositional analysis in one critical way: whereas decompositional analysis has a huge number of possible solutions, synergistic analysis has only one possible solution. And that one solution can be proven mathematically to be the optimal capability map for that particular enterprise at that particular time.

Roger Sessions, the co-inventor of this system and methodology, will be discussing this patent and it pragmatic importance is reducing the complexity and cost of large IT systems.
