    Challenges in IS evolution benefit assessment
    (Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Kankaanpää, Irja; Koskinen, Jussi; Tilus, Tero; Sivula, Henna; Lintinen, Heikki; Ahonen, Jarmo J.
    In this paper, the challenges of information system evolution benefit assessment are reviewed. Classical investment criteria and their advantages and disadvantages with respect to evolution options assessment are studied. The following potential challenges in evolution investment decision making were identified: selecting a proper analysis method, acquisition of suitable metrics and follow-up data, and valuation of the results. A preliminary framework, ISEBA, was developed to address these challenges.

    Software evolution strategy evaluation: industrial case study applying value-based decision model
    (Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Tilus, Tero; Koskinen, Jussi; Ahonen, Jarmo J.; Lintinen, Heikki; Sivula, Henna; Kankaanpää, Irja
    This study aims at supplementing the empirical basis of using software evolution evaluation methods in industrial settings. An industrial case study applying Value-Based Decision Model (VDM) for software evolution strategy evaluations is presented. VDM considers the value of a legacy software system and proposes convenient evolution strategies. Use of VDM is characterized, and the case study described. VDM has been applied in case of a production-use, large-scale industrial legacy system. Results produced by VDM, VDM's evaluation, and system evolution strategy recommendations are presented.
