Automated Requirements Verification Using SysML

Presenter: Dr. Saulis Pavalkis

Abstract: Systems Modeling Language (SysML) is used to capture systems design as descriptive and analytical system models, which relate text requirements to the design and provide a baseline to support analysis and verification. This session will demonstrate how model of the system, expressed with sufficient precision, can be used to support early requirements validation and design verification, particularly when coupled with an execution and simulation environment. Additionally, we will show how to use test cases and associated verification procedures as combination of inspection, analysis, demonstration, and testing to verify that the designs satisfy the system requirements.
The session demonstrates:
*   Representing text-based requirements in Cameo Systems Modeler
*   Requirements traceability, gap and coverage analysis
*   Refining and formalizing requirements
*   Selecting verification method
*   Defining test cases and analysis models
*   Performing automated requirements verification
*   Recording verification results, generating verification reports

Information-based Requirement Development and Management

Presenter: Lou Wheatcraft

Abstract: This presentation proposes an Information-based Requirement Development and Management (I-RDM) approach to developing and managing requirements from the perspective that requirements should not be developed and managed separate from other system data and information model development and management activities. Instead, requirements should be developed and managed concurrently from the beginning of the project as an integral part of the data and information modeling activities. If done correctly, the Systems Engineering (SE) tools will adhere to data sharing standards that will result in the project having the ability to form an integrated or federated data and information model of the system of interest that includes all artifacts and work products generated during all SE lifecycle phases with established traceability that is accessible by both the requirements development and design teams. That way, the design team will not have to import an often-defective set of design input requirements and analyze those requirements, correct defects, and then develop their design model and resulting design outputs. Instead the design modeling team would work concurrently with the I-RDM team through scope definition, concept maturation and feasibility activities, defining stakeholder needs, transforming those needs into a well-formed set of design input requirement expressions. Using this concurrent data and information modeling approach, the start of detailed design would be a continuation of the data and information modeling activities that begin at the start of the project. Thus, the design output development activities would begin with a mature system data and information model rather than a set of requirements whose quality is questionable with no underlying data and information model from which the requirements were transformed.

Lean & Agile Enterprise Frameworks: Using SAFe 4.5 to Manage U.S. Government Agencies, Portfolios, & Acquisitions

Presenter: Dr. David Rico

Abstract: Dr. David F. Rico will give a presentation on "Lean & Agile Enterprise Frameworks: Using SAFe 4.5 to Manage U.S. Government Agencies, Portfolios & Acquisitions." Lean and agile methods are well-established models for managing high-risk, time-sensitive R&D-oriented new product development (NPD) portfolios products and services with demanding customers and fast-changing market conditions. In fact, lean and agile methods are now used by over 95% of public and private sector organizations worldwide. The Scaled Agile Framework (SAFe) is a de facto international commercial standard for managing large information technology (IT) intensive portfolios, programs, projects, and teams. SAFe is used for the purpose of scaling lean and agile principles to large organizations, enterprises, portfolio, and multi-project programs (for government agencies, acquisitions, and complex large-scale systems of systems). SAFe lean and agile portfolio management principles are now used by nearly 50% of organizations constituting 200,000 professionals in over 100 countries. Furthermore, SAFe is emerging as the body of knowledge for lean and agile portfolio management, program and project management, systems and software engineering, and new product development (NPD) in-general. SAFe is a multi-level model consisting of best practices, recommendations, guidelines, and tools for enterprise-wide lean and agile budgeting, portfolio and value stream management, cross-cutting enterprise-wide workflows and threads, management of complex acquisitions and programs, and multi-team project management, governance, and synchronization. At its most rudimentary level, SAFe provides the program management and systems engineering discipline necessary to build complex, enterprise-wide mission and safety-critical systems, while retaining the flexibility, adaptability, and market-responsiveness of lean and agile principles. Therefore, SAFe is emerging as the de facto industry standard for Global 500 firms, stall worth U.S. manufacturing industries and firms, top U.S. financial institutions, U.S. federal healthcare institutions, major U.S. defense contractors, and public-sector agencies such as the U.S. DoD.

Dr. Rico will establish the context, provide a definition, and describe the value-system for lean and agile portfolio, program, and multi-team project management (as well as performance measurement). He’ll provide a brief introduction to SAFe, highlighting its newest features linking lean-budgeting, investment management, and business cases to hypothesis testing-based innovation management, continuous integration, continuous delivery, continuous deployment, development operations (DevOps), and program objectives, increments, and releases. He’ll then walk the audience through each of SAFe’s four major levels and the associated principles, practices, and tools (illustrating case studies; tips, tricks, and techniques; and personal experiences along the way). He'll provide a closer look at SAFe's multi-tier requirements model of epics capabilities, features, and user stories; provide a detailed roles and responsibilities (RACI) matrix; explain and illustrate key SAFe metrics and related concepts, describe SAFe case studies and cloud computing applications, identify SAFe change management techniques and roadmaps; and close with SAFe adoption statistics, a summary, parting principles, lessons learned, further resources, and a host of related roadmaps, comparative analyses to competing frameworks, metrics, models, and quantitative performance outcomes. This briefing has been warmly received by multiple U.S. government agencies, contractors, and PMI audiences throughout Baltimore-Washington, DC.

Bio: Dr. Rico oversees a multi-billion-dollar IT portfolio. He’s been a technical leader in support of NASA, Navy, Air Force, and Army for over 30 years.

Requirements Re-Use Library

Presenter: Warren Smith

Abstract: The prevalence of Requirements Management Tools has created an opportunity for Engineering Organizations to improve productivity by re-using common requirements from one product version to the next. Unfortunately, simply using a requirements database does not translate to re-usability of those requirements on another program. WRAYN's studies have shown that as many as 70% of the requirements in a given specification can be re-used if structured properly in a Re-Usable Requirements Library database. This translates into real cost savings: As much as 40% of a given Systems Engineer's time is wasted re-engineering common requirements previously defined on other programs. This paper describes the key considerations and basic process of building a Re-Usable Requirements Library focused on a Database of Requirements, with a measured return on investment exceeding of 328%. It explores the investment required and utility of such a Database.
This presentation describes the very specific techniques and approaches used to build this library.

: Warren B. Smith is a Systems Engineering partner at WRAYN LLC. He has been supporting systems engineering tools and methods his entire career. In his 30+ years, he’s worked as a Systems Engineer, a Project Engineer, a University Instructor, and Entrepreneur. He’s worked in many facets of the field developing systems, testing systems and working for tool vendors. He spent 10 years as an entrepreneur, running his own MBSE Company with 7 employees.  Through his company, Warren developed Re-Use methodologies and deployed Agile techniques at seemingly inflexible organizations.

While he’s worked on a wide variety of systems including Military Helicopters, Nuclear Submarines, Military Vehicles, Spacecraft, Training Systems, Medical Devices and IT, he says working on Amusement Park Rides was the most fun!

Systems Engineering on Legacy Systems

Presenter: Paul White

Abstract: What are legacy systems? Why would you want to work on legacy systems? How can you build a successful engineering career in legacy systems? What are some strategies for working on legacy systems? In this presentation, we will explore these, and many other, questions. As engineers, we are the problem solvers of the world. We apply our creativity and technical expertise across many domains. We build state-of-the-art aerospace and automotive vehicles. We develop innovative ways to bring food and water to more people around the world. We produce ingenious technologies for delivering health care. We produce greener technologies and develop more efficient infrastructure. Legacy systems play a critical role in the systems we work on every day. Rather than thinking of legacy systems as “obsolete” or “outdated”, think of them, simply, as older systems that are still in use today. These legacy systems are still in use, because they fulfill their missions better than anything else in their domains. As a younger engineer, you can benefit greatly by working on legacy systems. As an older engineer, you can continue learning, growing your career, and mentoring the next generation of engineers. As we discuss legacy systems, we will present strategies for working on legacy systems. These strategies include gathering documentation, seeking mentoring, developing architectures, performing modification programs, sustaining the system, and replacing the system. We will show how applying these strategies can lead to a successful engineering career.

Formally: An informal introduction to Blockchain

Presenter: Darren McCarley

Abstract: Blockchain: You’ve heard the word. You’ve seen the commercials. You’ve been asked by friends or family. You still think blockchain is: a fad, an illicit payment method for nefarious activities, some kind of fake money used in a Ponzi scheme, [add your favorite myth here].
So, what IS blockchain? How does it apply to the enterprise? Are there more than one kind of blockchains? How does blockchain affect me?
We will attempt to dispel these myths and answer these fundamental questions with the “Formally: An informal introduction to Blockchain” presentation.
Audience participation is highly encouraged during the presentation. However, additional invitations for off line discussions are extended as well.

Verification and Validation of Behavior Models Using Lightweight Formal Methods

Presenter: Dr. Kristin Giammarco

Abstract: This presentation provides a method for exposing invalid behaviors in systems of systems (SoS) early in design, at the architecture level. The Monterey Phoenix (MP)-based method for conducting behavior model verification and validation (V&V) was developed after students ranging from high school to the graduate level began discovering unintended, invalid, and potentially high-consequence behaviors permitted by their designs. These unspecified behaviors were consistent with known requirements, but violated stakeholder intent. Examples from four models from different domains and developed by different students are presented, then used as a basis for developing a structured set of behavior model V&V criteria that may be applied to any MP model. Finally, the criteria are put into the context of a systematic method that guides modelers in a thorough V&V of the behavior model. The ease with which unspecified and potentially invalid behaviors were exposed by students at various levels of education suggests that this lightweight formal method for behavior model V&V is user friendly for application by practitioners who have basic skills in logic and logical thinking. Follow-on work will further test the method on other MP behavior modeling efforts, with an aim to improve and extend behavior model V&V criteria and the methods in which they are employed.

: Dr. Kristin Giammarco is an Associate Professor in the Department of Systems Engineering at the Naval Postgraduate School (NPS), where she teaches courses in system architecture and design, system integration, systems software engineering, and model-based systems engineering.

SE Fundamentals on Portfolio, Program, and Project Management (P3M)

Presenter: Dr. Tina Srivastava (Gigavation & MIT)

Abstract:The disciplines of Program Management and Systems Engineering are inherently intertwined. To develop and deliver complex systems, all three sides of the “iron triangle” (cost, schedule, and performance) must be known, traded, and evolved in consideration of the others. When there is tension and confusion over the  roles  of PMs  vs.  SEs,  programs  suffer  from  deadline  overruns  and  failures.  This presentation  will introduce the fundamentals of system program management. The

target audience includes professionals from both the systems engineering and project management spheres, including those seeking a deeper common understanding  and those  new  to  either  discipline.  Every  systems  engineer  must  understand  key  P3M fundamentals  in  order  to  critically  evaluate  and,  when  necessary,  credibly  challenge  management  on potentially unrealistic expectations related to project cost, schedule, scope, and risk. Advanced methods and tools of project management will be introduced in the context of managing complex projects. Finally, this presentation will discuss strategic issues and scenarios that cannot be fully predicted such as unplanned rework,  perceived  versus  actual  progress,  and  misalignments  between  work  breakdown  structures, organizations,  and  product  architectures.

: Dr. Tina P. Srivastava is currently serving as INCOSE’s Secretary since her election in 2015.

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.

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.

: David D. Walden, ESEP, formed Sysnovation, LLC in 2006. Sysnovation is focused on Systems Engineering consulting and education/training.

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.

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.

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.
