This paper presents a method for evaluating and selecting off-the-self software components to be reused in software development. The paper describes the main motivation and principles of the method and provides a provides a detailed description of it. The method has been tried out in two case studies and initial results of these studies are reported. * This(More)
This paper reflects on three cases where the focus group method was used to obtain feedback and experiences from software engineering practitioners and application users. The focus group method and its background are presented, the method's weaknesses and strengths are discussed, and guidelines are provided for how to use the method in the software(More)
This paper presents the OTSO method for reusable component selection. The OTSO method has been developed to provide a basis for evaluating and selecting reusable components for software development. The main characteristics of the OTSO method include (i) a well-defined, documented process, (ii) hierarchical and detailed evaluation criteria decomposition and(More)
This paper aims at identifying critical factors affecting organization-wide implementation of requirements engineering (RE) processes. The paper is based on a broad literature review and three longitudinal case studies that were carried out using an action research method. The results indicate that RE process implementation is a demanding undertaking, and(More)
This paper describes experiences from two organizations that have used the Riskit method for risk management in their software projects. This paper presents the Riskit method, the organizations involved, case study designs, and findings from case studies. We focus on the experiences and insights gained through the application of the method in industrial(More)
We report findings from a survey that has been conducted in Finland to study how the software product companies have matured and evolved over the years. In addition to introducing some key terms for characterizing the software product business, we provide some overall data on the sector, and discuss some specific issues related to the software R&D process(More)
This paper describes how measurement data and experience can be captured for risk management purposes. The approach presented is a synthesis of the Riskit risk management method and the Experience Factory. In this paper we describe the main goals for risk knowledge capture and derive a classification of information based on those goals. We will describe the(More)
