Presentations from North Texas Chapter Meetings

Chapter Meeting - September 12


Presenter: Dr. Long Dong
Abstract: In the current environment, Affordability has more weight than ever due to improved technology and other aspects of engineering that drive more demand for efficiency and agility. Within the systems engineering community, there is a huge opportunity for engineering better systems that serve both:
•solving customer’s complex problems and
•providing the incentive for long term growth.

The presentation highlights some relevant research and introduces a methodology for systems engineers to address such demand and complexity within the defense industry. Two major takeaways:

(1)the differences in understanding of affordability between contractor and customer, and
(2)affordability is not just profitability; it’s an ongoing assessment for any complex systems or system of systems developer.

: Long Dong has a PhD in Systems Engineering from Southern Methodist University (SMU). He conducts research in systems engineering with focuses in systems design maturity assessment, systems engineering capabilities maturity, program management and systems affordability and systems effectiveness. He has a Bachelor degree in Electronics Engineering and Technology, Master of Business Administration (MBA), and a Master of Science in Systems Engineering from SMU. He has worked at Lockheed Martin Aeronautics for 17 years. He served as Technical Development Vice President of INCOSE, North Texas Chapter in 2016.     

Chapter Meeting - August 8

Systems Engineering is as Much About the Journey as the Destination

Presenter: David D. Walden, ESEP, co-owner and principal consultant for Sysnovation, LLC.

:  “Success is a journey, not a destination. The doing is often more important than the outcome.”

                  -Arthur Ashe

Systems engineering done poorly is obvious – missed requirements, integration issues, verification concerns, etc. Systems engineering done well is often transparent – either not noticed or assumed to be due to something else. To outside observers, many times including champions and sponsors, successful systems and the resulting systems engineering artifacts and work products appear “obvious.” They see an artifact such as a system boundary diagram or N-squared diagram and they intuitively think it was stable and known from the beginning and assume it was created in a straightforward manner with trivial or no effort.  However, the reality is that the artifact evolved through the deliberate application of systems engineering and the intentional interactions of the team.  This paper describes the importance of the systems engineering journey and how to impress upon others the need to take that journey on every project.

Chapter Meeting - July 11

We Need More Jack Sparrow, Savvy? A Swashbuckler’s Guide to System Modeling with SysML

Presenter: Michael J. Vinarcik, ESEP-Acq, OCSMP-Model Builder—Advanced

Abstract: SysML is often presented as complicated, difficult to understand, and software-biased. It has also been portrayed as solely a collection of diagrams. Nothing could be farther from the truth; although SysML has a high level of essential complexity (Brooks), the systems it describes are equally complex. This paper draws upon lessons learned from leading a system modeling effort using SysML and establishes parallels to leadership principles from Captain Jack Sparrow (a character in Disney’s Pirates of the Caribbean films). It also considers some aspects of elegance in design and modeling and provides practical insights into how to represent relevant information in a SysML model. A particular emphasis will be placed on modeling methods and how to maximize the value of work products derived from “traditional” SysML content.

:Michael J. Vinarcik is a Senior Lead Systems Engineer at Booz Allen Hamilton and an adjunct professor at the University of Detroit Mercy. He has over twenty years of automotive and defense engineering experience. He received a BS (Metallurgical Engineering) from the Ohio State University, an MBA from the University of Michigan, and an MS (Product Development) from the University of Detroit Mercy.

Chapter Meeting - June 13

Enabling Repeatable SE Cost Estimation with COSYSMO and MBSE

Presenter: Barry Papke, Director of Professional Services for No Magic Inc.

:In their paper on “A Generalized Systems Engineering Reuse Framework and Its Cost Estimating Relationships,” (Wang, Roedler, et al. 2014) present an approach for estimation of systems engineering effort that extends the COSYSMO equation to account for the effort associated with Design With Reuse and Design For Reuse classification categories in the Generalized Reuse Framework.  Implementation of this approach for cost estimation clearly depends on two critical items: (1) the ability to accurately and consistently count the size drivers; and (2) the ability to calibrate the model equation.  As part of future work, they also describe the potential to use this approach as a management tool in architecture development – “a cataloging mechanism in organizing components of reference architecture.”  This paper presents a practical implementation of the COSYSMO cost estimating relationship through extension of a Model Based Systems Engineering (MBSE) modeling environment with SysML for estimating end-to-end systems engineering effort in developing a system.  The approach provides a new way of rapidly creating cost estimates, conducting cost-based analysis and trade studies with full traceability from the cost estimation parameters back to the architecture of referenced system of interest.

: Barry Papke is the Director of Professional Services for No Magic Inc. and actively teaches and consults worldwide on Model Based Systems Engineering (MBSE), system design with SysML and enterprise architecture development with DODAF/UPDM.  Prior to joining No Magic, he spent thirty-two years as a systems engineer, operations analyst and program manager with L-3 Communication, Raytheon and Lockheed Martin.  Barry is an active member of the INCOSE Agile and Security Working Groups and participates each year in the International Workshop and International Symposium.  He also works with other INCOSE chapters around the US supporting/participating in local chapter workshops and events.  Barry has a Bachelor of Science in Mechanical Engineering from Texas A&M University and a Master of Science in Systems Engineering from Steven’s Institute of Technology.

Life Without Systems Engineering - Is It an Option?

Presenter: Kelly DeFazio, Professional Engineer, Director of F-35 Production/Producibility Engineering

: Systems Engineering is still a baby.  Born around the 1940’s by Bell laboratories, as a result of their need for the system of products and industry in communication. Other traditional forms of engineering design as a science have been around for centuries upon centuries, so why is systems engineering so important now? NASA quickly adopted this new approach to engineering. They saw the need for integrating a system of systems in order to get a man to the moon and back to earth safely.  So is Systems Engineering a technical solution need or just a government born project created to spread commerce across a varied team of contractors? Often, program management cuts this function off after completing the program’s Systems Requirements Review (SRR) treating systems engineering budget as a source of discretionary funds.  After all, “the requirements are complete – now - on to hardcore design”,  so why not cut systems engineering budget?  Hmmmmm, is Systems Engineering really a requirement? 

: Kelly DeFazio is Director of F35 Production Engineering for Lockheed Martin Aeronautics.  Her responsibilities include manufacturing engineering, test engineering, manufacturing planning and root cause and corrective action across all F35 production sites. Kelly was the Courtland Site Director for LMSSC responsible for Procurement through Assembly Integration & Test (AI&T) and delivery of Missile Systems.  In addition, she managed and maintained the 660+ Acre ordnance rated facility with over 125K Sq Ft of production floor space.
