In all the debates about what drove the world economy into its worst recession in decades, rarely does the concept of enterprise architecture come into the discussion. Yet, perhaps it should.

 In a new book published in concert with the Society for Information Management (SIM), respected technology professor Leon Kappelman makes the argument that countless decisions based on flawed and outdated enterprise models, helped lead the global economy down the path to recession. Technology was not directly to blame for the failure of the banks and investment houses that began the chain reaction into a recession, but the lack of an enterprise-wide vision and corresponding implementation of technology, did prevent the institutions from being able to fully understand their exposures, he contends.

 “All the stove pipes were humming along fine, but nobody understood the entire picture, the inter-dependencies,” says Kappelman.

 The new book, titled the SIM Guide to Enterprise Architecture, has been three years in the making, so while it is not based on the events that took place over the last year, Kappelman says he was able to watch the results of not having an enterprise architecture take place time and time again. Kappelman is a professor of information technology and decision sciences at the College of Business in the University of North Texas and a Fellow at the Texas Center for Digital Knowledge. The book was produced in concert with the SIM Enterprise Architecture Working Group. SIM is a national association of chief information officers and IT leaders, with 31 chapters.

The book provides readers with an understanding of the key concepts behind enterprise architecture (EA), and how it can help CIOs accomplish the often-elusive objectives of business-IT alignment, agility, simplification, process optimization, legacy replacement and data integration.

“EA is one of the essentials in the survival took kit for organizations in these times,” says Kappelman.
