The story of my involvement with business architecture

I mark the beginning of my involvement with business architecture at the point I joined Pacific Bell as their Data Architect.  The company had been through a significant modeling exercise, which resulted in an enterprise-wide data architecture, based on an extensive functional business model.  Over a several year period I led the effort to drive this down into implementable levels of detail, both from a process, and from a data point of view.  We were careful to model the human work as well as the automated part, and achieved a number of successes that changed procedures with little or no impact on the supporting applications.  We also achieved success in using architectural models to communication with Bellcore, the primary IT supplier to the Bell companies.

I began to take a public position on modeling and architectures at the enterprise level, including an article in Database Programming and Design magazine and numerous talks to industry groups.

I left Pacific Bell to do contact work with Charles Schwab and others, where I continued to develop and refine business modeling methods, largely process-related.

I joined IBM in 1994, where I maintained a focus on business modeling and business architecture for over 15 years. I developed a technique for modeling business language as a precursor to more IT-oriented methods such as E/R diagrams and other forms of data modeling.  I published an article in IBM Systems Journal on this technique.  At a time IBM was consolidating methods, I led the work to create a standard set of work products in the "business domain".  I consistently represented the business architecture point of view during a project that was creating architectures for enterprise solution structures.  I had another article in Systems Journal in the special issue on this ESS project.

I was IBM's representative for a couple of years on the Business Architecture Working Group of The Open Group.

Throughout my time in IBM I continued to apply business architecture methods on client engagements, including occasions when IBM itself was the client.
