Request This Speaker


Ron Kratzke is a Principal Systems Engineer in the Professional Services division at Vitech Corporation and has over 30 years of experience in engineering management and systems engineering. He spent the first 20 years of his professional career as a U.S. Navy Surface Warfare officer specializing in nuclear power surface ship engineering. During his naval career he achieved specialty recognition in nuclear power plant operation, surface missile systems, and electronic warfare. Kratzke was introduced to the practice of systems engineering in the twilight of his navy career while working on the Navy staff in the Pentagon, participating in integrated mission area analysis and developing capability requirements for the Navy in coordination with the Department of Defense Joint Staff.

Following his navy career, Kratzke spent 12 years supporting advanced systems design for a number of government organizations including: the Department of Defense, Department of Homeland Security, Defense Advanced Research Projects Agency, Defense Threat Reduction Agency, and the Joint Program Executive Office for Chemical and Biological Defense. Over this time frame he has had responsibility as a Chief System Engineer, Chief System Architect, and Project Manager. Kratzke has used CORE software on several system development projects since he was first introduced to CORE in 2007.

Kratzke has a BA in statistics from the University of Rochester, a MA in international relations and strategic planning from the Naval War College, and a MS in applied science from Southern Methodist University. He is a member of the International Council on Systems Engineering (INCOSE) and the American Society for Quality (ASQ) and is a Certified Six Sigma Greenbelt.

Presentation Topics

Model-Based Systems Engineering (One Day, Half Day)

The classic systems engineering domains (Requirements, Behavior, Architecture, and Testing) are all typically treated as and managed separately. Complexity and size often necessitate the use of a tool or tools to manage the domain. Tools are selected in each area and teams of “experts” manage the development and changes that take place. Problems arise because the domains are not actually discrete and unrelated. As the system design evolves, domains impact each other.

Many methods have emerged as attempts to answer the problem of developing the system as a system. From the plan-driven discipline of the classic waterfall approaches to the emphasis on responsiveness and flexibility in the agile school, these methods have all sought to produce a system solution for customer problems. All, however, have created their own set of problems and limitations.

This course discusses an approach to system design and improvement that is more agile than the traditional plan-driven methods and, at the same time, maintains the disciplined systems view avoiding the pitfalls of component engineering. We will discuss the concept of systems thinking and approach and the importance of understanding the business process components of the system. We will explore the delivery of capability that is value-adding for the customer in a meaningful time frame without losing sight of the system context.

Half-day format

A shorter treatment of the one-day MBSE course, the half-day version treats the topics covered in the longer course in a survey fashion designed to raise awareness, rather than develop understanding at depth.

Test and Evaluation Practices Using MBSE Tools

The presentation will explore a schema for a model-based management of system V&V activities beyond the “traditional” Verification Cross Reference Matrix (VCRM) required in system requirement documents. This extension will explore options for test activity planning and resourcing of test events, test event tracking, test risk management, and test plan progress.

Ron will demonstrate how to answer the following questions using the V&V facility built in to CORE:

  • What is the overall time required to complete a series of test events?
  • What concerns and risks do we have in our system test plan?
  • What resources do we need to complete the system test events?
  • How can we shorten the time required to complete a testing sequence?
  • How to monitor the progress made on completion of system testing?

Compliance in an MBSE Environment

The presentation will explore a methodology for expanding the CORE 9 schema to allow the system design team to track design compliance and process compliance.

Often times the system design team is attempting to satisfy more than one regulatory design structure. Ron will demonstrate a schema extension to allow traceability of the system requirement to multiple regulatory documents.

Additionally, the system design team is often required to provide evidence that the system design is being designed in accordance with a particular process. Ron will demonstrate a schema extension that traces design elements to process elements and the quality inspections usually used in process audits.
