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...

The fundamentals of a good decision-making are, first, clear understanding of the decision itself and, second, the availability of properly focused information to support the decision. Decision-making techniques help with both these problems. However, the techniques should be thought of as aids...

Time series forecasting has a long track record in many application areas. In forecasting research, it has been illustrated that finding an individual algorithm that works best for all possible scenarios is hopeless. Therefore, instead of striving to design a single superior algorithm, current...

A key problem in the development of information systems is understanding features of the development process. To this end, in recent years, considerable interest has been focused on modelling processes. In this paper, the results of an empirical investigation into the use of prototyping in...

Drawing on recently published data, this report examines some of the trends in travel e-commerce. Using a case study approach, the author examines in detail some of the e-business models impacting on the travel industry both in the Business-to-Business (B2B) and Business-to-Consumer (B2C)...

Process modelling is gaining increasing acceptance by software engineers as a useful discipline to facilitate both process understanding and improvement activities. This position paper builds upon previous work reported at the 1997 ICSE workshop on process models and empirical studies of...

Over the years, there has been much interest in modelling processes. Processes include those associated with the development of software and those business processes that make use of software systems. Recent research in Systems Engineering for Business Process Change highlights the importance of...

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...

Over the last 5 years a quiet revolution in business systems development has taken place towards the use of enterprise-wide, off-the-shelf software solutions. At the end of 1997, BusinessWeek estimated the value of this global enterprise applications package (EAP) market at $10billion and still...

Most practitioners recognise the important part accurate estimates of development effort play in the successful management of major software projects. However, it is widely recognised that current estimation techniques are often very inaccurate, while studies (Heemstra 1992; Lederer and Prasad 1993)...
