Security is still the main obstacle that is preventing businesses from moving towards the Cloud, which makes choosing the right Cloud service provider CSP a critical decision. We propose in this paper a methodology for evaluation and selection of Cloud security services based on a Multi-Criteria Analysis (MCA) process using a set of evaluation criteria and quantitative metrics. We then give a general...
In this keynote talk we propose the use of a capability-driven approach to enterprise modeling in order to capture the intertwined relationship among design requirements and environment, as well as the interplay of requirements and design artifacts for the purpose of facilitating enterprise agility.
Service-dominant logic, called S-D logic, proposed a new thought oftheoretical foundation for service economy from a service centricviewpoint, but basic terms and their relationship are not representedin technical form. We first formalize S-D logic in a mathematical form. In addition to the terms that have already been introduced in S-D logic, we define terms of 'capability' and 'potential'. These...
Traditional university benches are gradually being replaced with the intensification of Open and Distance Learning (ODL) mode. With more courses going online, the main challenge is to bridge the ‘separation’ between distance learners and tutors. In this respect the Discussion Board (DB) is gathering great interest and has become the locus of considerable research. The objective of this paper is to...
While fans of classical music were found to be underrepresented on social media and music streaming platforms, they constitute an important target group for music recommender systems. We therefore focus on this group of listeners and investigate a wide range of recommendation approaches and variants for the task of music artist recommendation. Within the group of classical music listeners, we further...
Enterprises face the challenge of rapidly adapting to dynamic business environments. The traditional approach to process management is only partially appropriate to this new context, and calls for the advent of new, evolutionary business processes. This new approach attempts to address specific issues related to flexibility and adaptation such as design of easily adaptable processes, dynamic handling...
Frequently requirements are written in natural language which may cause communication problems-misunderstandings. Misunderstandings are sources of risk that can severely impact the whole software development project. Since patterns and templates are tools for improving the quality of requirements, the question arises whether they can be treated as risk guards. In the paper we propose a method based...
Online shopping stores are a new hype in Jordan, and consumers are still not used to buying products online without touching and testing these products, they are also not used to paying online. The intention to buy online is affected by both technology factors and socio-cultural factors specifically trust.
With the looming urgency of e-Health technology mandated certification, privacy protection implementation and e-Health reporting in the year of 2014, service providers have to conform to the latest e-Health regulations (i.e., the "Final Rules of 2014") in the United States. We investigated the Service Context Management Solution for both the CE (Covered Entity) and BA (Business Associate)...
In Adaptive Case Management (ACM) systems, knowledge workers have the flexibility to deal with unpredictable situations. Compared with a classical BPM approach the extensive prescriptive process analysis and definitions are replaced by context-sensitive proposals, which is more suited for knowledge-intensive work. Thus, it is vital that ACM systems support knowledge workers with knowledge captured...
It is still an open question how to achieve a proper balance between the cost and value of requirements elicitation. When deciding to assign time and other resources to elicitation, one needs to know what its effectives would be. In the paper we investigate the Structured Elicitation of Non-functional Require-ments(SENoR) method. The method is composed of a sequence of short brainstorming sessions...
Enterprise systems development projects (ESDPs) often face requirements uncertainty (RU). Thus, it is essential that their project managers can cope with it. In order to gain insights into managing different RU situations, we conducted a longitudinal interpretive case study. We investigated the requirements analysis phase as well as subsequent phases of an ESDP in an international insurance company...
Entrepreneurial opportunities are a crucial starting point of the entrepreneurial process. However, reliable and replicable methods for systematically searching, framing, developing and assessing opportunities are still undeveloped. This article describes an action-research case study based on an experimental workshop performed in Beijing, China, in the context of an entrepreneurial platform called...
In today's knowledge-based economy, education is not only an essential instrument for knowledge acquisition and self-development, but also a mandatory tool that enables students to secure a good job, gain respect in society, and develop a personal identity. The importance of having the intellectual curiosity, ability to effectively apply the acquired knowledge/skills and job expertise becomes even...
There is a growing interest in applying the technical debt metaphor to investigate issues related to the tradeoff of the likely long-term costs associated with software design shortcuts for expected short-term business benefits in terms of increased earlier functionality. We propose an optimization model that contrasts the patterns of technical debt accumulation in a software product with the patterns...
Service-Oriented Architecture (SOA) provides a framework for service composition and reconfiguration. In addition to making composition decisions by considering functional attributes, technology for composition by meeting non-functional requirements such as QoS is also needed. In this paper, we present an approach to compose business process by considering context-based service reputation. Since some...
The aim of our research is the integration of personas into the requirements engineering process. The persona technique enables a better understanding of users' characteristics and thereby highlights the user needs in software development. We identify fundamental supporting purposes of personas for the requirements engineering process and match these benefits to the activities of the process.
Most human centric business activities, like the handling of an insurance claim or the design of an IT solution, do not follow a formal process model word-by-word. While there are often underlying processes in place, the real business operation typically encompasses a wider scope of actions. It includes unstructured segments of human activities, additional documents and interactions, the integration...
Businesses are, nowadays, keen on organizing their business processes in the most flexible way, as to cope with the tough competition. Two major concerns are emerging, while dealing with the construction of new process functionalities: (1) shortening the development periods, and (2) managing the privacy risks. An effective solution for dealing with both concerns, consists of reusing fragments of existing...
