System Qualities Ontology, Tradespace and Affordability (SQOTA) Project – Phase 4

This task was proposed and established as a result of a pair of 2012 workshops sponsored by the DoD Engineered Resilient Systems technology priority area and by the SERC. The workshops focused on how best to strengthen DoD’s capabilities in dealing with its systems’ non-functional requirements, often also called system qualities, properties, levels of service, and –ilities. The term –ilities was often used during the workshops, and became the title of the resulting SERC research task: “ilities Tradespace and Affordability Project (iTAP).” As the project progressed, the term “ilities” often became a source of confusion, as in “Do your results include considerations of safety, security, resilience, etc., which don’t have “ility” in their names?” Also, as our ontology, methods, processes, and tools became of interest across the DoD and across international and standards communities, we found that the term “System Qualities” was most often used. As a result, we are changing the name of the project to “System Qualities Ontology, Tradespace, and Affordability (SQOTA).” Some of this year’s university reports still refer to the project as “iTAP.”This material is based upon work supported, in whole or in part, by the U.S. Department of Defense through the Office of the Assistant of Defense for Research and Engineering (ASD(R&E)) under Contract HQ0034-13-D-0004.This material is based upon work supported, in whole or in part, by the U.S. Department of Defense through the Office of the Assistant of Defense for Research and Engineering (ASD(R&E)) under Contract HQ0034-13-D-0004

7e Nederlandse testdag, Eindhoven, 8 November 2001 : proceedings

These are the proceedings of the seventh edition of the Nederlandse Testdag (a.k.a. Dutch Testing Day), held on November 8, 2001 in Eindhoven, The Netherlands. The increase in the complexity of software and hardware systems was the predominant concern in the software design of the last decades. This increase is still going on today. and mastering this complexity is possible, only by investigating, discussing and evaluating methods and techniques for testing such systems. The Nederlandse Testdag serves as a forum in which researchers from the industry and the academia discuss and present their latest experiences and theories in the area of testing. The initiative for organising the Nederlandse Testdag is, and has always been, the result of the combined efforts of the Dutch academia and the industry. The Nederlandse Testdag is an annual event which was first held in 1995. This year's edition again consists of one invited presentation by Jens Grabowski, on ITCN-3. and six regular presentations, both from the academia and from the industry. The presentations capture a broad field of the entire testing spectrum. In the presentation by Martin Gijsen (CMG), test automation for Graphical User Interface (GUI), dedicated and embedded systems according to the TestFrame methodology is explained. Klaas Mateboer (Collis) presents the test-tool Conclusion. René de Vries (University of Twente) reports on specification testing in practice and illustrates this by means of an example. In the presentation by Loe Feijs (Eindhoven University of Technology), testing is related to game-theory. Marcel Verhoef (Chess) and Bertil Oving (NLR) present their experiences using real-time simulation, UML and VDM to obtain more reliable spacecraft avionics. Finally, Ben van Buitenen (Baan), provides an insight in service pack testing: how to efficiently test customised software components and packages. The organisation of the Nederlandse Testdag is grateful for the sponsorship it received from the Eindhoven University of Technology, the Eindhoven Embedded Systems Institute, and the financial support from Dutch Research School IPA. We are very much indebted to CMG and Telelogic's willingness to sponsor this event financially. Over the years, both companies have profiled themselves as companies investing both time and resources in advancing the current state in testing. Finally, the organisation thanks Marcella de Rooij and EIize Russell for their organisational assistance

Analysis of software engineering principles from an engineering perspective

Software engineering has recently emerged as a new engineering field in a continuing evolution. Software engineering is a discipline whose aim is the production of high quality software, but lacks maturity compared to other traditional engineering fields. Traditional engineering fields have their own principles originating from physics, chemistry and mathematics. However, since the software engineering discipline is not based on natural laws, establishing a set of principles is more challenging. This research on the set of candidate fundamental principles will contribute to a better understanding and possibly, to the teaching of the principles of software engineering and it will help improve the content of the software engineering body of knowledge (SWEBOK) Guide from an engineering perspective. This research work investigated the issue of software engineering as an engineering discipline using Vincenti categories of engineering knowledge; identified engineering fundamental principles from a set of candidates; and finally investigated the lack of explicit and systematic descriptions of these principles and their application, as in the SWEBOK Guide. The two main research objectives are the identification of the fundamental principles of software engineering from the 34 candidates principles; and the description of operational guidelines for these principles, based on the content of the SWEBOK Guide. To achieve these objectives, the following research methodology was used. The main phases of this research methodology are: the analysis, from an engineering perspective, of software engineering and the set of 34 ftandamental principles candidates; the identification of the software engineering principles in the content of the SWEBOK Guide - ISO TR 19759; the description of the operational guidelines on the basis of the content of the SWEBOK Guide and aligned with the IEEE standard 1362-1998 Concept of Operations (ConOps) Document. The main outcome of this research study is the identification of a set of nine software engineering fundamental principles and the description of operational guidelines
