Visual modeling languages propose specialized diagrams to represent behaviour and concepts necessary to specify IT systems. As a result, to understand a specification, the modeller needs to analyze these two types of diagrams and, often, additional stateme ...
For organizations to flourish in a changing environment, their business processes need to be flexible. Designing flexible business processes is a challenge. We use Weick’s theory of organizing to propose some principles for designing flexible business proc ...
In this paper we describe the successful use of RE methods in a project at Procter and Gamble UK. We identify two main elements for this success. The first element is the combination of methods from P&G and academia (Adoption Methodology and Lightswitch). ...
Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these ...
Enterprise Architecture (EA) requires modeling enterprises across multiple levels (from markets down to IT systems). Providing tool support for such models is a challenge (e.g. model containment hierarchy, navigation difficulties, problems to relate elemen ...
Enterprise Architecture (EA) requires modeling enterprises across multiple levels (from markets down to IT systems) i.e. modeling hierarchical systems. Our goal is to build a Computer Aided Design (CAD) tool for EA. To be able to build this CAD tool, we ne ...
Enterprises need to create and maintain the fit between their business processes and their business process support (BPS) systems. This frequently requires re-engineering of business processes. If the business processes design ration-ales are made explicit ...
Enterprise Architecture (EA) is a relatively new domain that is rapidly developing. The primary reason for developing EA is to support business by providing the fundamental technology and process structure for an IT strategy [TOGAF]. EA models have to mode ...
Visual modeling languages have specialized diagrams to represent behavior and concepts. This diagram specialization has drawbacks like the dif-ficulty to represent the effects of actions. We claim that visual contracts can de-scribe actions in a more compl ...
Creativity is about bringing unforeseen change to habitual ways of doing things. Understanding the challenges of introducing innovation in organizations is, therefore, essential during the requirements phase of today’s computer systems design projects. How ...
