This will be our regular Chapter meeting for June 2017. Food & drink provided at no charge - just let us know you are coming. (Note - no meeting in July)
NOTE LOCATION: At The SPACECOAST FAB LAB 2475 Palm Bay Road NE (across the street from the Harris).  See directions below.

Topic: About the Unified Architecture Framework
Speaker: Eric Barnhart
About the Presentation:
Over the years, the defense industry has attempted to create a common architecture to enable systems architects, decision makers and procurement professionals  to speak the same language.  One of the earliest efforts was the Technical Architecture for Information Management (TAFIM), a layered approach to describe systems.  TAFIM evolved to DoDAF 1.0, a complex framework for decision-making.  DoDAF 1.0 evolved to 1.5, which greatly improved the descriptive capabilities, and then DoDAF 2, which enhanced the underlying information metamodel to be more easily understood.  Meanwhile, the British Ministry of Defense was modifying DoDAF to include their own additions and terminology to the metamodel.  MoDAF was born from DoDAF.  Not to be outdone, the North Atlantic Treaty Organization (NATO) evolved MoDAF to the NATO Architecture Framework (NAF.)  So much for commonality…

With the advent of MBSE, it became apparent that a UML/SysML approach to the architecture frameworks was necessary.  This gave birth to the Unified Profile for DoDAF and MoDAF (UPDM), a profile extension to UML and SysML that allowed existing tools to create framework models.  UPDM 1.1 was a workable but flawed implementation, followed by UPDM 2.0 which more closely followed the MBSE concepts inherent in SysML and UML.  Now we have the initial versions of UPDM 3, which is a comprehensive overhaul and modernization of the framework,  Rather than continue to use the old UPDM identity, the Object Management Group has renamed UPDM 3 to be the Unified Architecture Framework (UAF).

This presentation serves as a practical introduction to UAF, and an overview of the framework.
About the Speaker:
A long, long time ago (the 1980s) Eric Barnhart graduated with a degree in Electrical Engineering, but found himself thrust into the world of software with his first job at the NASA Johnson Space Center. While there he became exposed to the real world of engineering, including bureaucracy, bloated processes and failed programs. He was reading articles in defense and aerospace trade journals that continually told of major programs that went over-budget, failed or were canceled. There was one very obvious commonality to all the failures; the system engineering efforts, especially requirements elicitation, were either non-existent or very poor.

Eric realized that the lack of systems thinking was the number 1 problem behind most engineering project failures, so he gravitated to systems engineering. He decided his mission in life was to improve systems engineering, and especially requirements elicitation and management. He wanted to make a difference.

Over thirty years later, Eric realized system engineering has not significantly changed. We still have poor system engineering practices. Lessons-learned are never implemented. Projects continue to fail and go over budget because poor system engineering continues to be the number one problem. Yet, he still wants to improve the systems engineering discipline before he retires. His personal vision is evolving at
