When almost anyone in business can answer what their value proposition is, not all of them will be able to answer what their value process is. The number will even vary of who can answer what their business process is. But it is necessary to know the ‘value processes’ of the proposed value based on which ‘business processes’ are derived. The ability to incorporate between the value processes and the business processes is one of the crucial factors that play for the companies very significant roles to be competitive in today’s challenging market. A number of research works can be found on value creation and value supply but none of them clearly explains the complex relationships between the value process and the business process or the importance of incorporation between these two in e-business modelling. In this paper we clearly define the value process and the business process and show the depth of relationships and the importance of relationships between them in e-business modelling with an illustration.

To deal with complex customer needs, enterprises increasingly form constellations, rather than just operate on their own. Cisco Systems and Dell are good examples of organizers of such constellations in their own industries. An important problem while designing these constellations is the selection of a performing enterprise for each value adding activity in the constellation. In this paper, we propose a -based approach to do so. We use the existing - methodology to represent a value constellation formally, and extend - with VA3; a step-wise approach that assists in selecting enterprises for performing value activities. How VA3 practically works, is illustrated using a case study on Cisco Systems.

Revenue models define a company creates their revenues and hence they are an integral part of business models. While a lot of research on business models and revenue models of the e-Business already exists, there is a shortfall of a concept to derive appropriate software architectures for the underlying software system directly from these models. This is interesting since a software system for companies of the e-Business is the fundamental basis to operate this business in practice. In this paper a concept is introduced to derive an important part of the overall software architecture for business models based on a characterization of its revenue model. For that purpose, a ‘classification cycle’ is defined including a set of criteria which enables you to conclude technical decisions for the design of a software architecture. Using this classification cycle, a variety of revenue models can be identified. Within this paper we focus on the specific revenue model subscription of services as one example. The derived architecture serves as a software reference architecture for all business models which are based on this type of revenue model. It means that in case a software system has to be developed for a business model using this revenue model, the software architecture presented in this paper can be used as a sample solution to refer to. Thus, it helps architects to derive a fundamental part of the overall software architecture in an easy and efficient way.

The system we propose supports a partner selection process in an e-business environment. The system evaluates partners’ supply capabilities and market conditions changed over time with multi-criteria, including quantitative and qualitative criteria. It helps selecting the optimal partners for maximizing revenue under a level of supply risk. The proposed system has been applied to partner selection problem under the supply chain of an agriculture industry.

Heterogeneous customer requirements in combination with technological improvements enable new or improved customer-driven business processes. The management of such processes requires a deep but flexible integration of enterprises. In this context new forms of cooperation like E-Collaboration, describing the efficient and effective collaboration of participants in a value-added network, arise. In order to manage customer-driven business processes across such networks, existing concepts for business process management need to be adapted and extended. In this paper an E-Collaboration architecture is presented, that shows how cross-enterprise, customer-driven processes can be planned, implemented and controlled. The architecture is based on the differentiation of global and local knowledge in the widely used Architecture for Integrated Information Systems (ARIS), developed at the IWi. Another important building block is the life-cycle-model that serves as a guideline for the process-oriented creation and operation of collaborations towards a common customer-driven production and bundling of goods and services.

Monitoring of Service Level Agreements (SLAs) is required to determine if the Quality of Service (QoS) provided by a service provider satisfies the expectations of a service consumer. Although tools exist that can generate the software required to evaluate SLAs from the SLA specifications themselves, the code required to gather metric data is still predominantly coded by hand: a time consuming task. In this paper we describe an SLA monitoring implementation that can generate metric data gathering software directly from machine readable SLAs. Assuming that an organisation specialising in SLA monitoring and evaluation may not wish to be tied to any one particular middleware platform and/or SLA language, we aim to provide generic monitoring services that may be suitable for use in heterogeneous environments. We demonstrate the flexibility of our approach by providing monitoring solutions for observed systems implemented using Web Services and Enterprise Java Bean (EJB) middleware using a third party SLA language.

In this paper, we propose a framework capable of personalization of both the access and the behavior of an e-office. Our solution is based on ACE software agents, partially prepared by (and for) office supplicants, executed in both user personal devices and the e-office network. The main goal of our framework is to provide a universal system for monitoring and notifying about information changes, on one hand, and user-defined customization of e-office services, on the other hand. The framework enables service personalization, user-defined combining and “pipelining” of services, individual brokerage among services and supplicants, and personalization of information delivery. The framework makes it possible to adjust fixed, closed software environment of an e-office to individual requirements and expectations of different users.

After the initial phase of E-Government and the exaggerated expectations for the new internet-based technologies, a pragmatic state of mind has evolved during the last few years. Thereby, it is especially the evaluation of the related financial benefits that has become a crucial aspect. The paper presented outlines a process-driven approach for the analysis of technology-driven performance impacts based on performance indicators. From a German perspective, existing evaluation concepts were concretized for the case scenario of German Plan Approval Procedures.

This paper describes a framework that supports knowledge modeling and sharing within public administrations, and a prototype of such a knowledge-sharing system. We will first give a brief theoretical introduction on processes of knowledge creation, transfer and application, and then we will present our framework and discuss how it relates to these processes. We will furthermore illustrate this with a case study and show the architecture of the prototype we developed in this context.

The increasing complexity of e-Government services demands a correspondingly larger effort for management. Today, many system management tasks, such as service verification and re-configuration due to changes in the law, are often performed manually. This can be time consuming and error-prone. The main objective of the OntoGov (IST-2002-507237) project is to overcome the above mentioned problems by developing a semantically-enriched platform that will facilitate the consistent configuration and re-configuration of e-Government services. This paper outlines the overall OntoGov platform and demonstrates how the Service Modeller can be used to consistently model e-Government Services.
