Ironically, VistA like many systems that are highly successful, is now threatened with self-extinction due to its need for continuous growth and the inability of MUMPS, the language it is written in, to sustain its continued evolution.  VistA suffers from a form of software arthritis common among many legacy systems. Due to its age, size and complexity VistA is brittle, inflexible and resistant to change, and its maintenance costs have gone through the roof, compromising the VHA’s ability to grow and evolve Vista as the foundation for a 21st century medical delivery system for its veterans.

In 2005 the VHA estimated automated modernization of VistA could save the VHA upwards of $3 Billion compared to redevelopment, or manual replacement.  With the announcement today by The Software Revolution, Inc (TSRI), (the world-leading supplier of architecture driven modernization (ADM-based) solutions), of its open-source Transformation Blueprint ^® for OpenVistA, TSRI has made a huge start on this daunting challenge.  For those who might care to understand, the OpenVistA Transformation Blueprint ^® is a major step towards achievement of the VHA's goal of modernizing its Electronic Healthcare Record  system for its veterans. 

OpenVistA Casestudy

TSRI’s OpenVistA^® Transformation Blueprint ^® provides the complete target Java code and UML design for the transformation of all 2.1 Million lines of OpenVistA^® and 120,000+ lines of Fileman MUMPS code.  The OpenVistA^® Transformation Blueprint ^® is far more than a mere language translation.  It is a massive multi-million page (300GB) web-based software design and architecture document consisting of navigable hypertext of the 'As-Is' MUMPS and 'To-Be Java' hyperlinked to hundreds of thousands of State Machine Graphs, Cause-Effect Graphs, State-Transition Tables, Control Flow Graphs, Data-Flow Graphs, Structure Charts, Data Element Tables, Class Diagrams expressed as scalable graphical diagrams that richly document all of the MUMPS and target Java/J2EE code. The Transformation Blueprint ^® is both an application portfolio as well as a complete architectural roadmap towards a modernized OpenVistA^® and Fileman. Every statement of MUMPS in OpenVistA^® is shown side-by-side with its transformation into Java/ J2EE along with an extensive array of software property-oriented metric indices (e.g. fan-in, fan-out, complexity, redundancy, dead code, etc) for navigation to the code measured by the property. 

To learn more about TSRI’s transformation of OpenVistA^® and the company’s plans for evolving OpenVistA^® towards a modernized universal EHR system of the future, read the Chapter 12 casestudy: Veterans Health Administration’s VistA MUMPS Modernization Pilot in William Ulrich and Philip Newcomb’s new book Information Systems Transformation: Architecture-Driven Modernization CaseStudies, just published by Morgan Kaufmann, February 2010 as part of the Object Management Group (OMG) OMG Series.
