How do you think the "New Management" reacts to the use of the Zachman principles (otherwise known as Eanterprise Architecture Planning) that Principi mandated before he left. How can such wilful ignorance of the broad picture endure if the "management" is to respond to the CMU-SEI criticisms? Reasonable mastery of EAP would understand the state of the Technical Infrastructure unless willful ignorance prevails as it did during the Gnomes of Darkness days 25 yrs ago.

That article certainly points to the risks of adding on applications to a legacy system. And if you never change the legacy system the kind of consequences described are inevitable. The design and culture of VistA was to always be changing the "legacy" (after all, the minute a project is finished and the product deployed, it becomes "legacy"). That kind of change takes constant effort ... which means resources for things that don't always appear on the surface to have any immediate benefit. Shut down that culture and process and VistA ends up looking just like the problem Comair had ... so it shouldn't really come as any surprise how new management now feels about VistA ... the earlier decisions were self-fulfilling.

Here is a timely article from CIO magazine on the risk and consquences of neglecting a mission critical system while waiting for something better......

"Bound To Fail" The crash of a critical legacy system at Comair is a classic risk management mistake that cost the airline $20 million and badly damaged its reputation.

That was deemed to be too "costly" for things like lab, scheduling, etc. CPRS continued to be retooled to some extent (but "OrderstuffReporting" has been stuck on "version 3" since December 1997). Halt retooling for most parts and they'll certainly be "old". Is there newinin VistA? Yes, but that doesn't change the things that are indeed old. Much retooling could be done to considerably reduce maintenance costs andfact test the Service Oriented Architecture (M supports it well in fact)ina more gradual manner that would engender far less risk than turning our collective backs on VistA entirely.
But "based on proprietary technology"? That's a howler.

"VistA is a solid system, but it's old, too expensive to maintain and based on proprietary technology, McFarland said. HealtheVet, he said, will be built on commercially available systems and therefore be able to interact with other platforms in the VA's inventory."
This quote cannot be accurate....it might be if it was Dubya that was being quoted....the inaccuracies are breathtaking. Perhaps I'm getting too old to maintain and my reasoning is starting to fail....and everything I have read about VistA for the last 10 years is wrong.....
