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:
• 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,
15-20 active companies: EDB, Vital, DnVS, Telenor R&D, … Abelia/IKTNorge etc.

Ex. EVISOFT: Evidence-based Software
Improvement
• NFR industrial R&D project, 2006-10. 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.

• Help (“facilitate”) IT companies to improve, by pilot projects in
each company: e.g. on cost estimation and risk analysis, UMLdriven 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

Researcher school (1)
• Det felles mål for forskerskoler er å heve
kompetanse og innovasjonsmuligheter rundt ITutvikling i Norge. Vekt på samarbeid mellom
forskning og næringsliv, lokalt-sentralt.
• De konkrete mål for nasjonale forskerskoler er:
styrke forskerutdanningen i Norge med
kvalitetsfremmende tiltak:
– forskingskoordinering/ledelse, bedre veiledning og oppfølging,
ekstra (metode)seminarer, gjester, bistillinger, utenlandsopphold,
reiser o.l.
20
Researcher school
• Typisk størelse: 15-20 stip. og 6-8 veiledere, egen
leder og et styre med eksterne medlemmer. For hver
forskerskole vil slike kvalitetstiltak kunne dekkes
med inntil 3 mill. kr per år i 8 år fra NFR, dvs. ingen
vanlig stip./postdocfinansiering som må hentes
annetsteds. 20 slike forskerskoler i alt de neste to år
(2008-2010), finansiert fra NFR. Søknadsfrist 4. juni.
• Mulige faglig fokus: åpen kildekode, smidige
metoder, modellbasert utvikling, helseinformatikk,
”informasjonssystemer”, mobilitet, interaktivitet, ...
