Work in Empirical Software Engineering

• Incremental, evolutionary development– down-scaling/optimization of RUP– changeability decay and rework

• Maintenance– 109 maintenance tasks were analysed in a large org.

• Schema evolution– Database schema modifications logged for 1.5 years

• Effort estimation– Expert judgement vs. models– Use case points estimation

• UML use cases - guidelines• Software architecture

– Various logging techniques, “think aloud protocol”

• Student experiments– Dec. 99: 12+40 students on two design alternatives re changeability– Sep. 00: 140 student on impact of effort estimation actual work– Oct. 00: 140 students on guidelines for writing UML use cases– Dec. 00: 20 students on schema evolution impact analysis

• Industrial experiments– Case tool evaluation (Telenor)– Software architecture evolution (BBS)

Plans

So far:

Mostly industrial case studies and student experiments

Future:

Industrial Software Engineering Experiment Laboratory

Opportunity:

Together with NTNU (Conradi), we will form a research group (1 of 3) at a new Center of Excellence at the old Oslo airport. We plan to build a lab with appropriate apparatus for observing/logging persons/teams who carry out experiments or real work

Collaboration with ISERN members so far

• Reidar Conradi: SPI etc.

• Claes Wohlin: Software architecture etc.

• Lionel Briand: OO metrics etc.

Benefits from ISERN

• Collaboration on research methods and concrete research issues

• Viewpoints from experienced ISERN people on how to build up our CoE/ISEEL

• Guest researchers from the ISERN community (short – long periods, PhD students – professors)
