Electronic intermediaries play an increasingly important role in supporting the coordination of buying and selling organizations. There is much discussion about the preferred information architecture of e-intermediaries and the added value for buying and selling organizations. Domain-specific characteristics of the trading situation should be taken into account when evaluating the added value of the information architecture of an e-intermediary. The information architecture determines the way the mutually dependent activities of buying and selling organizations are coordinated. This influences the added value and acceptance of an intermediary. In this article we first discuss a simulation approach to evaluate the added value of the information architecture of e-intermediaries. Thereafter, we discuss the main coordination characteristics of influence on the information architecture based on the information, facilitating, matching, and trusted roles of the e-intermediary. We use these characteristics to evaluate the potential added value of an intermediary in an empirical study. The added value is determined by simulating a real company situation and comparing this situation with a hypothetical future situation including an e-intermediary. In the last part of this article we draw some conclusions with respect to the added value and characteristics of e-intermediary information architectures and the limitations of this approach.

The pattern language for e-business provides a holistic support for developing software architectures for the e-business domain. The pattern language contains four related pattern categories: Business Patterns, Integration Patterns, Application Patterns, and Runtime Patterns. These pattern categories organise an e-business architecture into three layers-business interaction, application infrastructure and middleware infrastructure-and provide reusable design solutions to these layers in a top-down decomposition fashion. Business and Integration Patterns partition the business interaction layer into a set of subsystems; Application Patterns provide a high-level application infrastructure for these subsystems and separate business abstractions from their software solutions; Runtime Patterns then define a middleware infrastructure for the subsystems and shield design solutions from their implementations. The paper describes, demonstrates and evaluates this pattern language.

This paper distinguishes between the business domain, the application software domain, and the Information and Communication Technology (ICT) platform domain. It analyses historical developments in each of these three domains and shows that they experienced parallel development. The parallelism can be explained by mutual influence and alignment. Innovation in one domain may enable or drive developments in another. In order to be able to analyse alignment patterns, the notions of business architecture, application software architecture, and ICT platform architecture are introduced and defined. Interdependent historical developments sometimes demonstrate a radical change. Each can be described as a shift in "dominant design", and we identify six such changes in the history of the modern enterprise. Professionals and scientific researchers working in Information and Management can benefit from these insights by assuming that radical changes in dominant designs will affect their field in the future according to the same pattern.

A key requirement to today's fast changing economic environment is the ability of organizations to adapt dynamically in an effective and efficient manner. Information and Communication Technologies play a crucially important role in addressing such adaptation requirements. The notion of 'intelligent software' has emerged as a means by which enterprises can respond to changes in a reactive manner but also to explore, in a pro-active manner, possibilities for new business models. The development of such software systems demands analysis, design and implementation paradigms that recognize the need for 'co-development' of these systems with enterprise goals, processes and capabilities. The work presented in this paper is motivated by this need and to this end it proposes a paradigm that recognizes co-development as a knowledge-based activity. The proposed solution is based on a multi-perspective modeling approach that involves (i) modeling key aspects of the enterprise, (ii) reasoning about design choices and (iii) supporting strategic decision-making through simulations. The utility of the approach is demonstrated though a case study in the field of marketing for a start-up company. (C) 2016 Elsevier Ltd. All rights reserved.

Enterprises are increasingly organising their activities and IT support around key business processes. These processes and their interrelationships may be identified in a process architecture. Ould (2005) claims that the Riva method identifies the process architecture that an organisation should have, and asserts that organisations in the same business have the same process architecture. This assertion is not self-evidently true, and it has not been corroborated by the literature. But it is an important claim: if true, then process architectures could be reused either for new process development, or for appraising an organisation's existing architecture. We assessed the assertion by comparing the process architectures produced by applying Riva to two higher education institutions. The results partially support the view that an essential process architecture underpins higher education institutions, and also that for regulated business domains the optimal process architecture may be one based upon designed as well as essential business entities. The conclusion is that process architecture reuse, with its attendant potential savings of time and money, is worth investigating further, even though the extent to which the invariant assertion is testable may not be clear yet.

This article is a case study that explores the use of the Building Blocks portal design framework over a series of enterprise portal projects spanning several years. This article describes the business contexts that shaped each portal as it was designed showing the use and reuse of design and development elements based on the Building Blocks. This article discusses the changes and adaptations that shaped the elements of the Building Blocks design framework over time.
