Evidence-Based Structuring and Evaluation of Empirical Research in Requirements Engineering - Fundamentals, Framework, Research Map

The objective of the contribution is to develop and motivate an approach of structuring, evaluating, and representing empirical research results regarding requirements engineering. Therefore, the authors develop a framework in order to organize the area of interest. The use of this framework and an evidence-based classification system allows us to develop a research map which helps to structure identified empirical research while enabling the derivation of further research needs. Additionally, it supports the selection of methods, techniques, etc. in requirements engineering practice

Digital service innovation enabled by the blockchain use in healthcare: the case of the allergic patients ledger

International audienceBy combining the institutional approach and the rational model of digital innovation, there is increasingly a great interest in the implementation of blockchain solutions in healthcare but, until then concrete evidence for this type of project is missing. At the same time the healthcare sector, allergology in particular seems to face security (confidentiality, availability and integrity) issues and information audit trail weaknesses. For these reasons, our study focuses on the co-construction of a distributed ledger for patients allergies with healthcare professionals. The aim is to design and implement a reliable tool to deal with the availability , integrity and confidentiality of information about new allergies and distinguish between validated allergies and declarative allergies for the purpose of mitigating negative effects of unavailability of reliable information about patients allergies. This article defers the first step of our methodological cycle by explaining how collaboration is organized between Pikcio (blockchain technology provider) and allergists. As a result, we have first versions of some deliverables such as formal specifications, risk matrix document and a UML design (class diagram, use case diagram and sequence diagram) as the research project is iterative

PARADIGMS AND INFORMATION SYSTEMS AS AN APPLIED DISCIPLINE – A MODEL-BASED REPRESENTATION, PROBLEMS, AND SUGGESTED SOLUTIONS

Information Systems Discipline (ISD) is dominated by the two contrary paradigms of design science on the one hand and behavioral science on the other. Apart from that, research results are considered more or less relevant for practice depending on the respective paradigm. Conclusively, research communities following the paradigms are partly incompatible while, due to the notion of relevance for practice, the exchange between science and practice is hampered. Various “disconnects” hindering the collaboration both between design science and behavioral science and between science and practice emerged due to this. These aspects will be described and represented within a model-based analysis of the situation while suggestions from ISD literature on the topic will be presented and discussed. Considering that comparable challenges have recently been faced in the field of medicine, Evidence-based Medicine (EbM) emerged as a new paradigm to solve similar problems and is now well-established. We will present and discuss some attempts to transfer the evidence-based research approach from medicine and how they may apply to the equally application-oriented field of Information Systems

Systematic Review and Meta-Analysis of IS Security Policy Compliance Research. First Steps towards Evidence-Based Structuring of the IS Security Domain

Given the short supply of empiricism in ISS research, existing empirical evidence needs to be processed further than the scope of a single paper may allow. Other fields of science have long recognized the need for higher level analyses of research results in order to make them accessible to practitioners and develop a knowledge base. In our paper we perform an exhaustive literature research in the realm of empirical ISS research. As one of the recent research hotspots, we perform a systematic review of research results in Information Security Policy (ISP) compliance. We analyze and discuss the heterogeneity of research results and suggest a presentation format that may allow ISS practitioners to base their ISP design decisions on

Evidence-Based Information Systems: A New Perspective and a Road Map for Research-Informed Practice

Despite the increasing sophistication and quality of published work, the development of a cumulative body of knowledge and an evidence-base for information systems (IS) research still represents a major challenge. IS research is still predominantly undertaken by IS researchers for other IS researchers and not utilized to its full extent by IS practitioners or policy-makers. We focus on this problem and express the need for a new evidence-based research perspective. It is argued that it is time to refocus the efforts of IS academics (and practitioners) to develop a new evidence-base for IS research whereby it can more routinely inform, develop, improve and support IS practice. We contribute to this debate by defining evidence-based practice (EBP), its relevance to IS, and the need to develop an evidence-based approach. We look in particular at its brief history, and its subsequent evolution, development and widespread acceptance in Medicine; making reference to recent arguments and critiques of EBP in other disciplines such as software engineering and management. We espouse the need to develop a similar evidence-based movement and infrastructure within the IS research and practitioner communities and then put forward a possible road map for the development of Evidence-Based Information Systems (EBIS) that comprises 9 key initiatives. We conclude our argument by stating that the current extent, severity and impact of IS failures are unacceptable, emphasizing the need for a new perspective for IS research that encourages and incorporates EBP as a guiding principle to inform better IS practice
