Requirements Analysis and Verification for the Thirty Meter Telescope with OpenMBEE and the OpenSE Cookbook

This talk focuses on leveraging the Executable System Engineering Method (ESEM) which automates requirements verification (e.g. power and mass budget margins and duration analysis of operational modes) using executable SysML models. It demonstrates how the ESEM is applied in conjunction with OpenMBEE (an open source Model Based Engineering Environment) to create key engineering products (e.g. operational concept document) and specify, analyze, and verify requirements of the Alignment and Phasing System (APS) and the Narrow Field Infrared Adaptive Optics System (NFIRAOS) within the Thirty Meter Telescope (TMT) project. TMT is under development by the TMT International Observatory (TIO).


Robert Karban is a Project Systems Engineer in the Systems Engineering and Formulation Division at NASA/JPL. Robert leads the team providing the Systems Environment (based on OpenMBEE) to JPL users, and applies modeling on the Thirty Meter Telescope project. Prior to that, he developed control and instrumentation systems for large telescopes at the European Southern Observatory (ESO), applying model driven technology, and for particle accelerators at the European Organization for Nuclear Research (CERN). Robert is a Challenge team lead of INCOSE's MBSE Initiative, an OMG certified SysML professional, and co-chair of the OMG's revision task force for SysML. He started his career at Siemens Medical Devices developing System Software and received is M.S. in Computer Science from the Technical University of Vienna/Austria.

A pragmatic view from a practical perspective

What is a requirement engineer expected to deliver in context of software development within a large corporation? This contribution addresses the intersection of requirements engineering and design. From a practical point of view there are three main areas where requirements can originate from. These are business, technology and people. Requirements engineering is indisputably strong in eliciting and articulating requirements. However, these three areas of origin are not equally accounted for in the process of engineering requirements. Within Deutsche Bahn Group we therefore elaborated and discussed several problem hypotheses relating to the requirements process. We identified 13 critical issues and for each one a golden rule. We also compared the existing practice of requirements engineering with the established human centered design practice in context of an internal IT provider. Here again the fact came to light clearly that requirements themselves do not create a solution. A conceptional design is required to mediate the transformation from requirements to a solution. Here we see in the context of agile development some stumbling blocks that should be encountered. When we talk about design, we realize that design is a frayed term. In light of contemporary trends towards digital transformation we find that the purpose of design requires some re-shaping. Design problems can be referred to as “wicked problems” according to Horst Rittel. To tackle wicked design problems an integrated mindset of design and engineering is very useful. Equally important is the practice of design as a craft as well as design as a mindset. Several examples from inside Deutsche Bahn are described to illustrate such an integrated mindset. Returning to the intersection of requirements engineering and design it seems that from a practical perspective it is time for a new integrated approach that can be located in the emerging discourse of “digital design”. A discourse that has been started by the German Association for IT, Telecommunications and New Media and picked up the International Requirements Engineering Board, as well as the German Usability Professionals Association.


David Gilbert has worked in various operational and strategic Digital Design roles since 2007. Until 2015, he worked for various design agencies such as Scholz & Volkmer, Pixelpark, Mutabor or SinnerSchrader. The projects he has worked in have received over 25 international and national design awards. - Since 2015 he is working in the IT department of the Deutsche Bahn Group, where he holds the role of Chief Architect User Experience at the intersection of classic system-oriented and user-oriented software conception. From 2011 - 2016, he was a lecturer in UX Design at the RheinMain University of Applied Sciences, and has published various contributions to the topics of strategic UX design and digital design. He is a member of the IREB working group "Digital Design", deputy chairman of the Bitkom "Digital Design" working group as well as he is a member of the "Designforum Digital Experience" of the German Design Council.

Requirements collection and business process optimization for the development of an information system to replace a legacy system.

The Volkswagen Group operates an approximately 15-year-old back-end IT system, which shows symptoms of a legacy system (outdated process and IT documentation, error-prone, time-consuming maintenance, etc.) and that has to be replaced by a successor system. The presentation will first of all present the initial situation and the special challenges in the context of very large and over years grown legacy systems. In the second part of the presentation, the approach is presented in which (a) the requirements of the users and interface partners on the successor system and (b) the actually practiced as-is process were recorded with the help of interviews. In the third part, we discuss how the recorded requirements had been evaluated against the business process vision, possibly detailed, grouped and prioritized. In conclusion, problems and positive findings of the applied approach are summarized. In particular, we note that many pseudo-requirements had been captured and sometimes even implemented, and that some core requirements can only be captured based on acquired domain knowledge and target business process vision and not through interviews.

Natural-Language Processing Deep-Dive

Held on Monday

We will feature a deep-dive into Natural-Language Processing (NLP) Tools. As part of the NLP4RE workshop we will have a structured tool demo of some commercial NLP tools.
The vendors will first give an overview on their respective tools, give an open presentation on the NLP features of their tools and show the results of the tool capabilities on a “golden spec”, i.e. a specification that reflects the current state of writing natural-language based requirements specifications. The requirements specifications will contain typical deficits as we see them daily in specifications ranging from ambiguities and vague formulations to contradictions and redundancies.
As the tool have all their specific strengths in NLP processing, we expect a really interesting session that help you to understand what to expect from current commercial NLP tools in the requirements engineering area.

So far, the following tool vendors have confirmed their participation in the NLP Deep-Dive:

Requirements and Test Smell Analysis

Qualicen Scout features several different analyses to identify quality issues in requirements. From requirements that are hard to read, over inconsistencies in use cases, to requirements clones, Scout covers a whole range of potential problems. Furthermore, Qualicen Scout brings specific analyses for issues in manual test cases. Examples are overly long test steps and test flows that contain implicit forks. Also clones in tests are covered.
Dashboards give you an overview over KPIs, quality trends and hotspots. With Qualicen Scout, you can choose from a library of widgets to freely configure the Dashboard that you need. Most widgets are interactive and allow you to drill down into the quality data.
Document Visualisation
With Qualicen Scout, you can explore the quality findings directly within your documents. Locations with quality issues are highlighted within the document. Using filters, you can chose which types of issues you want to display.
Real-Time Analysis
As soon as your documents change, Qualicen Scout will detect this change almost immediately and re-run the analyses for the changed parts. Qualicen Scout shows you whether new quality issues have been introduced or whether existing issues have been fixed.
Tool Integration
Qualicen Scouts integrates with your current tooling landscape: Scout can import requirements and tests from various sources, including Qualicen PTC Integrity LM, Microsoft TFS, Visual Studio Team Services, GIT, SVN and the file system. Scout can also use LDAP for authentication.
