Empirical Evaluation of Software Maintenance Technologies

Technology evaluation is part of the decision-making process of any software organization. Unlike conventional wisdom, empirical evaluation strives to avoid biased conclusions by relying on observation and looking for pitfalls in the evaluation process. In this paper, we provide a summary of the maintenance studies presented in the session ‘Study and assessment of (new) technologies’ of the International Workshop on Empirical Studies of Software Maintenance (WESS '96), and also report on the working group discussion which focused on common problems and open issues in the field of technology evaluation. These empirical studies are then classified according to a multi-dimensional framework to synthesize the state of the research in technology evaluation and ultimately discover interesting patterns.
