    Lunch seminar on Design Science

    Today I had the chance to share with colleagues at SYSLAB my experience of the ERCIS Design Science summer school, which I attended at the end of August (ercis-phd-summer-school-design). I covered key points from literature intending to provide a broader scope of Design Science than what is covered by Hevner et. al. 2004 (the most well known paper on Design Science research). Furthemore, I briefly covered all main aspects of the area as tackled during the summer school. These could be summarized into a set of questions and open issues:

    • What is and what is not design science research?
    • What are the philosophical assumptions of design science?
    • What is an artifact in design science?
    • What is the/a design science research process?
    • What is a design science theory?

    • Open issues: the relation of a kernel theory and design science theory, epistemology in design theory, utility, how to codify design theory, etc.

    Here is the presentation
    (literature references used, coming from the ERCIS Design Science summer school, are listed in the slides).

    ERCIS PhD Summer School "Design Science"

    Last week I attended the 1st PhD summer school on”Design Science” organized by the European Research Center for Information Systems (ERCIS) on a sailing boat in the Netherlands.

    Along with another 12 PhD students and the two chairs of the summer school, Prof. Karlheinz Kautz (Copenhagen Business School, Denmark) and Dr.Dr. Björn Niehaves (ERCIS, University of Münster, Germany) we spent the week with seminars on foundation papers of “Design Science” (e.g. Hevner et. al. 2004, March & Smith 1995, Simon 1981, etc.) and its applicability.

    Our discussions and theme of the paper analysis evolved around 5 questions and a set of open issues:
    • What is and what is not design science research?
    • What are the philosophical assumptions of design science?
    • What is an artifact in design science?
    • What is the/a design science research process?
    • What is a design science theory?
    • Open issues: the relation of a kernel theory and design science theory, epistemology in design theory, utility, how to codify design theory, etc.

    It was a pleasure attending the seminars that brought up different views of the papers examined; putting on the table more questions on Design Science to be answered. It was a valuable experience especially for someone like me trying to clarify my research topic and research methods.

    More information about the summer school should be soon available via ERCIS: www.ercis.de

    REVVA 2 presentation

    As a member of the technical team representing the Swedish Defense Research Agency (FOI), Today, I had the opportunity to present the outcome of the work done within the REVVA 2 consortium. Under the auspices of the Simulation Interoperability Standards Organization (SISO), the project was focused on developing a generic and comprehensive Verification, Validation & Acceptance (VV&A) methodology for modeling and simulation (M&S) products. The outcome is meant to be submitted as an internationally recognized standard and recommended practice for the application of VV&A, the Generic Methodology for Verification, Validation and Acceptance (GM-VV).

    The GM-VV provides a generic framework to efficiently develop an argument to justify why identified models, simulations, underlying data, outcomes and capabilities are believed to be acceptable for deployment in the target (intended) operational (use) context. This argument is intended to support stakeholders in their acceptance decision-making process on the utilization the aforementioned M&S artifacts to satisfy their business goals. The methodology provides this support throughout the whole life-cycle of these (M&S) artifacts (development, employment and (re)use). More importantly, the GM-VV defines the required information and argumentation mechanisms that allow well-balanced and risk informed arguments for acceptance decision making with various levels of formality.

    The presentation can be found here:2009.04.08 REVVA2 for SYSLAB.pdf, while the full document set (the GM-VV Handbook, the GM-VV RPG and the GM-VV Reference Manual) can be found at SISO's product development group webpage.

    New group for PhD students

    A new group is launched today for SYSLAB's PhD students. The group is meant to host communication(e.g. the weekly lunch meetings as well as presentations held there, etc.) between the lab's PhD students.
  • March 29, 02:37 PM

    Verification, Validation & Accreditation of Modeling & Simulation

    I would like to thank you for inviting me to this social network.

    Currently I'm taking my first baby steps as a researcher, since i have just joined the group. I have recently completed my Master Thesis (EMIS program) working on Modeling & Simulation (M&S) and more specifically on proposing a tailoring method for Verification, Validation Accreditation of M&S products.
    My future research will evolve on the same area and i will be working closely with the Swedish Defense Research Agency (FOI).

    Show me how it’s done, please…

    Concerns have been expressed by regulators about dependency on Google’s algorithm for search results and the impact on business, as good intentions of engineers are not enough.

    …we can’t be sure that Google 10 years from now won’t be corrupt…“,

    therefore, Google is trying to show how to design a google-friendly website, but keeping its judgments secret; failure to conform will lead to undesired search results and most likely failure; this sounds more like a threat to me if anything else!

    “…Google executives say they do all they can to educate website owners about how to design their pages in a way that gives them the best chance of figuring prominently in search results. But they also say they cannot disclose too much of the inner workings of the search engine for fears of helping unscrupulous operators exploit the system...”

    (both quotes are from the Financial Times, Monday July 12th 2010)

    Apple explains how to hold an iPhone 4 to use the product without any antenna problems, or go pickup add-on bumper blablablabla, wtf? Pretty soon Apple will be releasing a relevant detailed specification manual with figures and everything, touch here, there, then twist and shout and after you stick it up your… you will probably have better reception.

    Instructions of use for a product or service is one thing, instructions of use for a faulty expensive product or for a sensitively dependent service is at least problematic (especially when coming from one dominant vendor)…

    Automobile manufacturers have shown the good example; when detecting a problem they withdraw parts and cars or repair the damage at their own cost. Of course, gadgets are not equally life-risky, however, this simply not appropriate policy, especially regarding how these two companies promote themselves.

    Obviously Blur’s There’s no other way would be the most suitable music bed for their campaigns

    Spotify: Jukebox revisited

    I’m kind of a regular at Bagel Street Cafe in Södermalm, Stockholm (I’m actually the mayor of this place ), which obviously means I enjoy their bagels and coffee a lot, let alone their friendly service (enough with the free promotion).

    Today I just experienced an unintentional add-on service which could be rooted back in the jukebox era.  They share an open playlist on Spotify where anyone can contribute. What happened was that when I just commented on the music played at the time, the girls at the counter told me they would gladly played anything I had contributed on their shared playlist, and so they did! (They also provide free wifi)

    In other words, just how a jukebox used to work,  customers can choose music right on the spot. The best part is that being Spotify based, all you need is a laptop/notebook/.. or phone and you can choose any music you like and added to their playlist (Spotify required of course).

    Spotisquare

    So next time you sit on a cafe check if they have a Spotify playlist, (e.g. Spotisquare is perfect for this) and go ahead add your tunes and I’m pretty sure they’ll gladly play it for you

    Jamie Does Athens: simplicity & more

    I just watched the latest, and last for this season, episode of Jamie Oliver’s series “Jamie Does“, where he visited my hometown, Athens. While watching the show a few thoughts crossed my mind, worth sharing. Thoughts regarding the current situation in Greece, around  tourism, and of course around food.

    Jamie Does Athens

    Greece today

    The timing of the show is great. At least for the British audience, but given Jamie’s popularity, the show is and will be reaching more parts of the globe (free & good advertising). For a change our country is not on TV just because we are on the verge of bankruptcy, but because one of the most popular, famous (you choose) chefs in the world acknowledges Greece, today, as a destination for food and more.

    During the show Jamie visits a taverna in Athens and he comments “I love the whole idea of Greek culture of eating out a lot“… “Greeks love to eat out, it’s part of their social scene“. Since the show was shot about a year ago, it makes me wonder whether the crisis will manage to alter Jamie’s remark and how soon.

    Tourism

    I’m only a tourist and far from an expert on this area, but I’d like to believe that someone (e.g. the Greek National Tourism Organization) invited Jamie Oliver to do a show and it wasn’t just his culinary interest or just to make an interesting show that drove him in Athens. Though I doubt it has crossed anyone’s mind, I could acknowledge that it might not have been relevant to the strategic planning of campaigns like live your myth, kalimera, etc. probably Jennifer Aniston walking around Kolonaki, bumping into the Prime Minister would have more impact (not real idea, just read it somewhere on twitter). If only one could find good uses of such free advertising…

    Based on the show, keywords or key concepts of Greece are the Acropolis, Zorba, Souvlaki, Mama mia, Greek honey, dried herbs, bouzouki, the sun, the sea, Greek Yoghurt, fish, meze, the Greek Salad. And No Moussaka! My point? Our national product is well described with overall relatively stable principles. We only need to sell it properly! And I see Jamie’s show as an opportunity to do so. Our “burden” is to preserve it, meaning at least gradually improve it to keep it going and support its stability.

    Food

    There was lemon in everything,  but the Greek Salad. Of course we love lemon, who doesn’t? I hope in terms of culinary interests from around the world, it should be an awakening. Primarily for Greeks to start appreciating their food, even if it takes a British chef to glorify the simplicity of our cuisine and spreading the word. Where there is souvlaki, rationale and logic mandate no junk food can exist! I’m pretty sure that Aristotle himself would have preached so too.

    Fresh grilled tuna ladolemono (referred as Greek lemon sauce)

    Kudos to Jamie Oliver for the show!
