Towards a Framework for Enterprise Information System Evolution Steering

Abstract

International audienceEvolution is characteristic to every Information System (IS) because of continuing changes in its environment. It is also a necessary condition for guaranteeing IS fitness to the organizational needs and requirements. Nonetheless, each IS evolution presents several risks towards its sustainability and further changes, and steering IS evolution is indispensable for any organization. In this work we propose a framework that aims to guide the actors responsible for IS evolution steering. The framework allows to reduce the uncertainty, which is inherent in the IS evolution, by providing the information necessary to realise IS evolution activities and to simulate their impact. It is composed of several conceptual models representing different IS dimensions (information, activities, regulation). In this paper we detail the IS Steering Metamodel (IS-SM), which is the main element of our framework

Evolution Models for Information Systems Evolution Steering

“…), and how they comply with regulations governing these activities (the definition of regulatory concepts, rules and roles). Although IS-SM is not the main subject of this paper (it was presented in [2,3]), it remains the bedrock of the framework, and is necessary to be presented for better understanding other models and illustrations. IS-SM is also the kernel model for implementing an Informational Steering Information System -ISIS.…”

“…We found the development of such an approach on conceptual modelling by designing a conceptual framework for IS evolution steering. Some parts of this framework were presented in [2] and [3]. In this paper we pursue our work and present one of its componentsthe operationalization of the IS evolution through the metamodel of IS Evolution.…”

Defining the Responsibility Space for the Information Systems Evolution Steering

“…In our previous work [2] we have introduced a conceptual framework for IS evolution steering. This framework includes several conceptual models each of them taking into account a particular perspective of IS evolution steering:…”

“…The framework constitutes the foundation for developing an Informational Steering Information System (ISIS). Up to now we only presented the general overview of the framework and its IS-SM model [2], and partially discussed the IS evolution models [3]. In this paper we focus our attention on the third part of our framework that deals with the notion of responsibility in IS evolution steering.…”
