What's Important is whether what you do  works over the long haul!

Dear Ken,
I've written this recommendation of your work to share with other LinkedIn users.

Details of the Recommendation: "In the course of a long technical career, if you are lucky, you have the opportunity to meet and work with a handful of people who are truly “world class” in a profession. Ken is one of these. In the early 1980’s Pacific Bell had undertaken the creation of a single, integrated, enterprise-wide personnel system. A team of over 40 developers were dedicated to this undertaking; it was a true “subject database system” integrating over one hundred existing independent applications – and we were in trouble. The SDLCs of the day (“classic” and “new” Yourdon, Gane & Sarson, etc.) were all process and event oriented – which really was not much help in bringing order to this entirely data driven problem domain. We needed a methodology that would allow us to integrate the multitude and provide a methodical approach to support the over 4000 identified reports – the combined output of the systems being integrated. 

And then we found Ken Orr & Associates. Ken’s methodology, Data Structure Systems Development (DSSD), was a fully-formed, Level 4 CMMI solution – ten years prior to the dissemination of the CMM and five years before the first fully functional relational database technology was available in the marketplace. Entirely driven by the structure of the data views produced from the system, the method took the development team through a fully defined process, step-by-step, from analyzing these views within the context of their workflows, deriving a minimal set of relational tables sufficient to satisfy all of the identified views, and developing of the update processes and system event calendar to keep the data current at the times it needed to be current. This method didn’t just identify all of the code processes; it derived those processes from the data structures supported. “Visionary” is not too strong a term for now, let alone over twenty-five years ago! 

DSSD brought order out of chaos, allowing us to proceed for the next four years, and to finally successfully deploy the Personnel Data Services System which served as the backbone personnel system at Pacific Bell for the next ten years. Did I mention that this system had a fully functional temporal database which allowed point-in-time queries for any time in the past, the present, or into the pending future? This was not some summary data warehouse, but al towed access to the full set of detailed operational personnel and organizational information. This temporal solution was driven by the method, not something added onto the solution. 

In recent years, Ken has focused mainly on the speaking circuit and individual consulting engagements, but his current practice rests upon having developed an end-to-end Level 4 SDLC twenty-five years before the industry had evolved to a place where his insights could be truly appreciated. With the coming of age of model-driven architecture and domain-driven development, the profundity of Ken’s insight’s are just now becoming apparent."
