The upstream activities of software development are often viewed as both the most important, in terms of cost, and the yet the least understood, and most problematic, particularly in terms of satisfying customer requirements. Business process modelling is one solution that is being increasingly...

The use of formal models such as Role Activity Diagrams (RADs) for analysing a process often hide what really happens during that process. In this paper, we build on previous research on informal aspects of the prototyping process and look at the key concerns that prototypers had during the...

As a means of contributing to the achievement of business advantage for companies engaging in ebusiness, we propose a requirements engineering framework that incorporates a business strategy dimension. We employ Jackson’s Problem Frames approach, goal modeling, and business process modeling...

Two intensive, longitudinal case studies were conducted at IBM Hursley Park. There were several objectives to these case studies: first, to investigate the actual behaviour of the two projects in depth; second, to develop conceptual structures relating the lower-level processes of each project...

Most MDA approaches are focused on Platform Independent Models (PIM) and Platform Specific Models (PSM) and the transformation between them. The more conceptual Computation Independent Models (CIM) or even unstructured information is often neglected, despite the importance of requirements...

Contracts between multiple business parties play an important role in a global economy where activities along the value chain are executed by independent, co-operating organizations. Information technology to enact a value chain is now being deployed in the form of ERP systems and service...

The upstream activities of software development projects are often viewed as both the most important, the least understood, and hence the most problematic. This is particularly noticeable in terms of satisfying customer requirements. Business process modelling is one solution that is being...

In response to the so-called "software crisis', software prototyping has been widely used as a technique in various stage of systems development since the late 70's, and, with the growing sophistication of 4GLs tools and environments, it has becoming a popular alternative to conventional...

Business process modelling is an area of work that is increasingly used in conjunction with software development. For example, many development methods note the importance of strategic or business modelling, typically as a prerequisite to analysis. In addition, Systems Engineering for Business...

Electronic marketplaces (e-marketplaces) have a profound influence on the way in which organizations manage their supply chains. Proponents of the e-marketplace concept suggest that web-based trading systems, such as World Wide Retail Exchange (WWRE) and GlobalNetXchange (GNX), would enable...
