This article presents an e-business modeling approach that combines the rigorous of IT systems analysis with economic value perspective from business sciences.

Two requirements engineering techniques, i* and e <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> value, work together to explore commercial e-services from a strategic-goal profitability perspective. We demonstrate our approach using case study on Internet radio

Real-world services - that is, nonsoftware-based differ significantly from Web services, usually defined as software functionality accessible and configurable over the Web. Because of economic, social, business importance service concept in general, we believe it's necessary to rethink what this means an ontological computational sense. We deal about OBELIX (ontology-based electronic integration complex products value chains) project has therefore developed a generic component-based ontology...

An extensive literature research in the fields of IT and business science reveals that service-related terms as service e-service have multiple interpretations within science, information computer resulting confusion. These three communities take part multi-disciplinary process realizing e-Commerce scenarios for services. Each community has its own role offering, uses terminology. In this paper we analyze different perspectives these on online provisioning concept. We introduce meanings...

In goal-oriented requirements engineering (GORE), one usually proceeds from a goal analysis to specification, of IT systems.In contrast, we consider the use GORE for design IT-enabled value constellations, which are collections enterprises that jointly satisfy consumer need using information technology.Designing constellation amounts designing architecture IT, business processes, and coordination processes across cooperating companies.The needed do such cross-organizational not only consists...

In this paper, we introduce e 3 alignment for inter-organizational business-ICT alignment. With the framework, create between organizations operating in an agile networked value constellation—which is a set of who jointly satisfy customer need—by (1) focusing on interaction constellation, (2) considering from four different perspectives, and (3) utilizing conceptual modeling techniques to analyze within perspectives. By creating actors ultimately contributes sustainable profitable...

Bitcoin is a widely-spread payment instrument, but it doubtful whether the proof-of-work (PoW) nature of system financially sustainable on long term. To assess sustainability, we focus bitcoin miners as they play an important role in consensus mechanism to create trust currency. Miners offer their services against reward while recurring expenses. Our results show that mining has become less profitable over time extent profits seem converge zero. This what economic theory predicts for...

Despite an urgent need for social and technological innovation to improve wellbeing of people communities in poor regions the world, information communications technology (ICT) service delivery has not yet been very successful with low levels literacy, infrastructures, limited purchasing power. High rates failure, reported various studies, point at a frequent mismatch between deployed technologies local needs contexts. Still, no practical field-validated methodologies ICT low-resource...

The concept of enterprise architecture (EA) introduced in the 1980s refers to business-IT alignment a single organization. has proven its utility practice IT management, but EA frameworks cannot deal with network organizations that are enabled by IT. assume hierarchically coordinated organization, where final responsibility for strategy rests management. characteristic feature is there no central coordinator responsibility. Yet, today's facilitated and they too must be aligned their...

Electronic commerce applications have special features compared to conventional information systems. First, because electronic usually involves yet nonexisting business activities, requirements for e-commerce be created from scratch rather than elicited. Second, design decisions about e-business models and the associated systems architecture cannot sequentially made in a decoupled way, technology considerations are strongly linked. On these counts, current methodology engineering is...

In this paper we present a framework for dynamic service bundling, which focuses on the exchange of valuable outcomes between customers and suppliers. The approach is based three components: A customer, broker pool in charge matching customer supplier perspectives performing cluster-based bundling process. applicability our proven by means case study educational industry.

The rapid growth of service coordination languages creates a need for methodological support design. Coordination design differs from workflow because process connects different businesses that can each make decisions independently the others, and no business is interested in supporting processes others. In multi-business cooperative design, are only supported by all if they contribute to profitability participating business. So order businesses, requirements should be derived model makes...

While exploring value Webs - cooperating enterprises it is common to view such from multiple perspectives: (1) the business perspective, (2) process and (3) information system perspective. The perspective explains why a Web can exist commercial whereas shows interacting processes of IT perspectives supporting architecture. These each take different on same phenomenon: Web. Because phenomenon for viewpoint need be consistent. This paper introduces an approach arrive at model that consistent...

Networked service value constellations, consisting of enterprises and customers working together to jointly provide a commercial service, can be analyzed from different modeling perspectives. Two such perspectives are (1) the perspective (2) process perspective. Value models, describing perspective, indicate which economically valuable outcomes exchanged between involved actors. However, model only shows what economic is exchanged, but not how this should accomplished. Therefore, understand...

This paper introduces a design methodology for business modeling from two perspectives. The value-web perspective models the creation, distribution, and consumption of goods or services economic value in network multiple enterprises end-consumers. goal is to create shared understanding all actors assess profitability. trust describes how webs can be expanded with trustworthy control procedures. enhance mutual confidence so as enable trading. A formal theory procedures setting...

Emerging Web services technologies provide an open infrastructure for automated business interaction, thereby creating new opportunities actors to collaborate within a networked constellation of enterprises via the Internet. The basis viable network (the supporting information system such enterprises) is value model that shows sound propositions all involved. Requirements engineering techniques can be developed support: (1) exploring alternative models, and (2) evaluating alternatives on...
