A Classification of

Abstract: The range of user requirements on multicast protocols is so wide that no single protocol will ever satisfy them. The set of multicast protocols can be classified using the user requirements, and the architectures, mechanisms, communications patterns, and policies used to satisfy these requirements. We provide such a classification, and illustrate it with several example protocols chosen to cover the range of features described.

User Involvement and MIS Success: A Review of Research

Abstract: User involvement in the design of computer-based information systems is enthusiastically endorsed in the prescriptive literature. However determining when and how much, or even if, user involvement is appropriate are questions that have received inadequate research attention. In this paper research that examines the link between user involvement and indicators of system success is reviewed. The authors find that much of the existing research is poorly grounded in theory and methodologically flawed; as a result, the benefits of user involvement have not been convincingly demonstrated. Until higher quality studies are completed intuition, experience, and unsubstantiated prescriptions will remain the practitioner's best guide to the determination of appropriate levels and types of user involvement; these will generally suggest that user involvement is appropriate for unstructured problems or when user acceptance is important. In order to foster higher quality integrated research and to increase understanding of the user involvement-system success relationship, the authors present the following: a conceptual framework into which previous research has been mapped that can provide direction to future efforts; a review of existing measures of user involvement and system success; a set of variables that have been proposed as potentially impacting the relationship between user involvement and system success.

Agile software development with Scrum

Abstract: The thesis describes the importance and characteristics of agile methodologies for software development, focusing on the currently most widely used methodology - Scrum. In addition to basic features and the presentation of the Scrum development process, the paper describes the specification of user requirements through user stories and their use in the above-mentioned methodology. It also presents the most widely spread user stories estimation techniques and gives a detailed examination of the technique called Planning poker. The paper concludes with a review of tools that support project management tasks and their comparison with the help of a decision model and the program DEXi.

User involvement: A review of the benefits and challenges

Abstract: User involvement is a widely accepted principle in development of usable systems. However, it is a vague concept covering many approaches. This study first clarifies the nature of user involvement and its expected benefits, and secondly reviews three streams of research, to evaluate the benefits and problems of varied user involvement approaches in practice. The particular focus of this study is on the early activities in the development process. An analysis of the literature suggests that user involvement has generally positive effects, especially on user satisfaction, and some evidence exists to suggest that taking users as a primary information source is an effective means of requirements capture. However, the role of users must be carefully considered and more cost-efficient practices are needed for gathering users' implicit needs and requirements in real product development contexts.
