IME: Faculty of IT, Mathematics and Electrical Engineering, five departments incl. IDI. IDI: Dept. of Computer and Information Science, 50 teachers, 75 PhD fellows,15 researchers. IDI: 12 PhD candidates and 150 master candidates per year. Over 100 taught topics. IDI: Ten research groups, incl. SU group.

3 SU: Who we are – what we do IDI’s software engineering group: Five faculty members: Reidar Conradi, Tor Stålhane, Letizia Jaccheri, Monica Divitini, Alf Inge Wang. Four researchers: Anna Trifonova, Sven Ziemer, Jingyue Li, Sobah Abbas Petersen. 16 active PhD-students, common theme: empirical software engineering research and practise. 30 MSc-cand. per year Research-based education: students participate in projects, project results are used in courses A dozen R&D projects, basic and industrial, in all our research fields – industry is our lab. Half of our papers are based on empirical research, and 25% are written with international co-authors.

10 SU motivation (0) Software essential in many important societal activities ,000 system developers in Norway – many without formal SW education. Still many challenges wrt. software quality and delivery on time and budget; cf. [US Standish report, 1995], cited in [PITAC, 1999], on projects for tailored software: –31% stopped before finish, 81 bill. $ loss/year (1% of GNP!) –53% have serious overruns (189% average), 59 bill. $/year Some challenges: –Web-systems: Manage time-to-market (TTM) vs. reliability? –Component-based development (OSS, COTS): quality, risks –Business critical systems –How do software systems evolve over time, cf. Y2K? –What is empirically known about software products and processes? –How can small companies carry out systematic improvement? –How to perform valid sw.eng. research in a university -- by student projects and having industry serving as a lab?

11 Research fields of SU group (1) Software Quality: reliability and safety, software process improvement, process modelling Software Architecture: CBSE with COTS/OSS, evolution Co-operative Work: learning, awareness, mobile technology, project work What is important for us: Empirical methods and studies in industry and among students, experience bases. Software engineering education: partly project-based. Tight cooperation with Simula Research Laboratory/UiO and SINTEF, active companies: EDB, Vital, DnVS, Telenor R&D, … Abelia/IKT-Norge etc.

12 Research fields of the SU group (2) Distributed Software Eng. Software and Art CBSE: COTS/OSS, Evolution, SCM Reliability, safety Co-operative work SPI, learning organisations, SE education Software quality Mobile technology Software architecture

16 Ex. EVISOFT: Evidence-based Software Improvement NFR industrial R&D project, NTNU, SINTEF, UiO/Simula, Vital. 3 PhD stud. (NTNU, UiO), 5-10 researchers, 10 active companies. NFR funding: 8 mill. kr/year, covers direct expenses. Project manager: Tor Ulsund, Vital ex.Geomatikk. Builds on SPIQ ( ), PROFIT ( ), SPIKE ( ) Help (“facilitate”) IT companies to improve, by pilot projects in each company: e.g. on cost estimation and risk analysis, UML- driven development, agile methods, component-based software engineering (CBSE) – coupled with quality/SPI efforts. Couple academia and industry: win-win in profile and effect, by action research. Empirical studies – in/across companies and with other projects General results: Method book, reports and papers, experience clusters, shared meetings and seminars
