Objective: Our objective is to describe how softwareengineering might benefit from an evidence-basedapproach and to identify the potential difficultiesassociated with the approach.Method: We compared the organisation and technicalinfrastructure supporting evidence-based medicine (EBM)with the situation in software engineering. We consideredthe impact that(More)
A consequence of the growing number of empirical studies in software engineering is the need to adopt systematic approaches to assessing and aggregating research outcomes in order to provide a balanced and objective summary of research evidence for a particular topic. The paper reports experiences with applying one such approach, the practice of systematic(More)
Background: In 2004 the concept of evidence-based software engineering (EBSE) was introduced at the ICSE04 conference. Aims: This study assesses the impact of systematic literature reviews (SLRs) which are the recommended EBSE method for aggregating evidence. Method: We used the standard systematic literature review method employing a manual search of 10(More)
ÐEmpirical software engineering research needs research guidelines to improve the research and reporting processes. We propose a preliminary set of research guidelines aimed at stimulating discussion among software researchers. They are based on a review of research guidelines developed for medical researchers and on our own experience in doing and(More)
DESMET was a DTI-backed project with the goal of developing and validating a methodology for evaluating software engineering methods and tools. The project identified nine methods of evaluation and a set of criteria to help evaluators select an appropriate method. Detailed guidelines were developed for three important evaluation methods: formal experiments,(More)
The Mean Magnitude of Relative Error, MMRE, is probably the most widely used evaluation criterion for assessing the performance of competing software prediction models. It seems obvious that the purpose of MMRE is to assist us to select the best model. In this paper, we have performed a simulation study demonstrating that MMRE does not select the best(More)
