	abstract = {Retrospective analysis is a way to share knowledge following the completion of a project or major milestone. However, in the busy workday of a software project, there is rarely time for such reviews and there is a need for effective methods that will yield good results quickly without the need for external consultants or experts. Building on an existing method for retrospective analysis and theories of group involvement, we propose improvements to the root cause analysis phase of a lightweight retrospective analysis method known as post mortem analysis (PMA). In particular, to facilitate brainstorming during the root cause analysis phase of the PMA, we propose certain processual changes to facilitate more active individual participation and the use of less rigidly structured diagrams. We conducted a controlled experiment to compare this new variation of the method with the existing one, and conclude that in our setting of small software teams with no access to an experienced facilitator, the new variation is more effective when it comes to identifying possible root causes of problems and successes. The modified method also produced more specific starting points for improving the software development process.},

	abstract = {More and more software projects use Commercial- Off-The-Shelf (COTS) software. Although previous studies have proposed specific COTS-based development processes, there are few empirical studies to investigate how to use and customize them to different project contexts. This paper describes an exploratory study of state-of-the-practice of COTS-based development processes. 16 software projects in Norwegian IT companies have been studied by structured interviews. The results are that COTS-specific activities can be successfully incorporated in most traditional development processes (such as waterfall or incremental), given proper guidelines to reduce risks and provide specific assistance. We have identified three COTS-specific activities - the build vs. buy decision, COTS component selection, and COTS component integration - and one new role, that of a knowledge keeper. We have also found a special COTS component selection activity for unfamiliar components, combining Internet searches with hands-on experimentation. The process guidelines are expressed as scenarios and lessons learned, and can be used to customize the actual development processes, e.g. in which lifecycle phase to put the new activities. Such customization crucially depends on project context, such as previous familiarity with possible COTS components and flexibility of requirements.},

	abstract = {The use of Commercial-Off-The-Shelf (COTS) software has become more and more important in software development. In COTS-based development, COTS component selection is the most crucial phase. Although some selection processes have been proposed, empirical studies are necessary to assess these processes. This paper describes an exploratory study by structured interviews of 16 COTS-based development projects in Norwegian IT companies. The results indicate that successful COTS component selection can be implemented without using formal processes, and projects with different contexts may use different selection processes. If members in new project has enough practical experience with actual COTS components, such experience can be the dominant factor in selection. In the case of using a new COTS component in the project, hands-on experimentation is needed as an effective way on evaluating the component.},
