10. SU motivation (0) • Software essential in many important societal activities. 50-60,000 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: • Empiricalmethods and studies in industry and among students, experience bases. • Software engineering education: partly project-based. • Tight cooperation with Simula Research Laboratory/UiO and SINTEF, 15-20 active companies: EDB, Vital, DnVS, Telenor R&D, … Abelia/IKT-Norge etc.
