Abstract: ”The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding, go out to meet it.” (Thucydides) Dies beschreibt die Aufgabe eines Architekten am besten. Denn geht es bei größeren Software Projekten um Qualität spricht man von Software-Architekturen. Und diese werden von Architekten entworfen, gepflegt, kommuniziert, gegebenenfalls auch verteidigt und natürlich verantwortet. In diesem Vortrag soll die Signifikanz der Software-Architektur im Allgemeinen und die damit verbundenen Aufgaben des Architekten im Speziellen klargestellt werden.

Speaker: Victor Sauermann ist Senior Software Architect bei der DATEV eG in Nürnberg. Zu seinen Aufgabengebieten gehören u.a. der Entwurf und die Bewertung von Architekturen. Aber vor allem die Etablierung und das Vorantreiben einer Referenzarchitektur innerhalb der Entwicklung bei der DATEV eG. Bevor er bei der DATEV eG begann, arbeitete er mehrere Jahre bei der Siemens AG in Erlangen und entwickelte sich vom reinen Software Entwickler und Netzwerk Administrator bis hin zum Software Architekten und Projektleiter.

Abstract: IT-Unternehmensarchitektur befasst sich damit, wie man komplette Anwendungslandschaften, beziehungsweise die IT-Investitionen eines Unternehmens so steuern kann, dass für das Unternehmen daraus (gemessen an seinen Zielen) der optimale Nutzen entstehen kann. Der Vortrag gibt einen Überblick über wichtige Prozess der IT-Unternehmensarchitektur und stellt einen musterbasierten Ansatz vor, mit dem man die eigene Funktion für IT-Unternehmensarchitektur so an die Gegebenheiten eines Unternehmens anpassen kann, dass man mit möglichst geringem Aufwand möglichst hohen Nutzen erzielt. Dazu benötigt man Zielmuster, Muster für Prozesse und Muster für Informationsmodelle.

Speaker: Wolfgang Keller befasst sich seit mehr als 20 Jahren mit dem Bau großer, individueller Softwaresysteme, meist für Versicherungen und Banken. Nach ersten Jahren bei sd&m (heute Capgemini) arbeitete er in verschiedenen Architekturfunktionen des Generali Konzerns, zuletzt als Chefarchitekt in Deutschland. Seit 2006 arbeitet er freiberuflich als Unternehmensarchitekt und Projektleiter. Er ist Autor diverser Fachbücher und sonstiger Publikationen.

Remark: Relevantes Buch für den Vortrag: Wolfgang Keller: IT-Unternehmensarchitektur, dpunkt Verlag, 2006. Vortrag basiert auf zweiter, überarbeiteter und erweiterter Auflage, erscheint Ende Februar 2012. Web: www.objectarchitects.biz

1. Research

In our open source software engineering research, empirical work is farthest ahead, with interesting results: For example, by analyzing developer work rhythms we were able to show that most open source is being developed weekdays, 9-5, on company time. No surprise, you might say, but someone had to prove it. In the same vein, we have been empirically analyzing open source programming behavior, with more interesting results on how to improve tools to be published next year.

Open source is not only software, but a collaboration model and a legal framework as well. The adoption of this collaboration model in various contexts only accelerated during 2011. We are actively researching open-source-based collaboration models for industry consortia and for firm-internal use (so-called „inner source“). IT user consortia provide IT user firms with lower costs and higher flexibility while avoiding strategic vendor lock-in. Inner source allows a software development firm to benefit from successful open source best practices and make its development more effective. Such work raises even more governance questions than before and we have been publishing accordingly [1] [3] [12] [13].

In our software engineering work we went public with our first open source project this year, the Sweble Wikitext parser. This component lets users parse in Wikipedia (and other Mediawiki content) and analyze its data. This component, developed by OSR Group Ph.D. student Hannes Dohrn, has quickly been picking up a user community with first contributions on the horizon. For more information, check out the project website at http://sweble.org [4] [6] [7] [9] [10] [11].

After a first failed DFG grant proposal in 2010, we are finally working on new proposals again, both for the DFG, the European Union framework program, and others. The EU proposals are about inner source and open source community processes.

Prof. Riehle traveled repeatedly to China in 2011 and intends to keep doing so. Informal collaborations exist with Prof. Schneider of City University of Hong Kong and Prof. Bai of Tsinghua University, and we hope to deepen these relationship and take them to the next level. Chinese research partners are a key focus of our international interactions.

Our industry sponsorship and collaboration has been accelerating. Next to SUSE and Google, our 2010 sponsors, who continued their sponsorship, we added Bearingpoint and Bosch as new 2011 project partners and sponsors. We are looking forward to more fruitful years of collaboration. We were also able to receive friendly financial gestures from GfK, Univention, Quinscape, and WeWebU and are looking forward to future collaboration as well.

In addition, we performed the usual services on journal (ISM, IEEE Software, SoSyM, JSS, IST) and conference committee (OSS, ICSE (SEIP Track), AOSD (Modularity Track), HT (Track 3)) review boards.

2. Teaching

We teach as part of the applied software engineering alliance at FAU. To our existing classes AMOS (the “agile methods and open source” lab course), FIRM (how software product firms work), and NYT (“nailing your thesis”, i.e. how to perform research) we added the new classes PROD (software product management) and ARCH (software architecture). These classes are co-taught with our industry lecturers Dr. Martin Jung, Dr. Erich Meier, Stefan Probst, and Michael Rohrmüller who we would like to thank for their engagement!

We are particularly proud of the product management class, for two reasons: First, product management is perhaps the most important function in software development organizations, yet it is almost completely being neglected in computer science university teaching. Second, we have started to develop our own set of (Harvard Business School-style) cases to improve the dire situation that little good teaching material is available.

A “case” describes in 5-10 pages a specific decision situation that a company once faced and we use it to guide the class discussion around that decision. At the end of the class session a real person from the case comes into class to discuss the students’ conclusions! For this, we are collaborating with local companies (and are still looking for more).

3. Entrepreneurship

2011 was the year when our entrepreneurship teaching was bearing first tangible fruits. The Mydosis project, an outgrowth of our 2010 AMOS class, received EXIST funding, about EUR 100,000. Congratulations to the team of Markus Stipp, Christoph Wille, and Johannes Link! [8] We have high hopes that Mydosis will help improve medical practices in pediatrics and turn a profit as well. For more information, check out http://mydosis.de.

Free Seas Ahoy!, the 2011 AMOS project, is on its way. Please find a first impression at http://fsahoy.com.

4. Public service

During 2011, Prof. Riehle provided his expert opinion in various forums. The two main noteworthy (and pro-longed) engagements that we can publicly talk about are his membership of

• an expert advisory board to one of the public foundations for the German Enquette Commission “Internet und Digitale Gesellschaft”, and
• an expert advisory board to the “Open Commons Region Linz”, which advises the city and region of Linz in their Open Government, Open Data, Open Source, etc. efforts.

Not surprisingly, Prof. Riehle has been spending a fair amount of time in Berlin this last year.

Thank You!

At the end of this year we would like to thank

• SUSE, Google, Bearingpoint, Bosch, Univention, GfK, Quinscape, and WeWebU for their new or continued sponsorship,
• Dr. Martin Jung, Dr. Erich Meier, Stefan Probst, and Michael Rohrmüller for their engagement in helping us teach practical software engineering and entrepreneurship, and
• Prof. Bernd Hindel, Prof. Detlef Kips, Dr. Norbert Oster, and Dr. Klaudia Dussa-Zieger for their collaboration as part of the Applied Software Engineering Alliance.

All the best for 2012! And please subscribe to our blog at http://osr.cs.fau.de for on-going information and late-breaking news!

For the Open Source Research Group,

Prof. Dr. Dirk Riehle, M.B.A.
