Meta-Modeling And Structural Paradigm For Strategic Alignment Of Information System

The information system is strongly sensitive to strategic evolutions of the enterprise: organisational change, change of objectives, modified variety, new objects and business processes, etc. With the objective to control strategic alignment of information systems, we propose an approach based on our extended enterprise meta-model ISO/DSI 19440. This extension is borrowed from the COBIT framework for IT processes. In order to better lead evolutions of the information system, this extension integrates necessary structures for developing systemic tools, based on a structural paradigm. In this work we propose to build an extension of the meta-model ISO 19440, so that we can explicitly bring the issue of alignment of various aspects of the information system. The strengths of the strategic alignment are interactions and couplings between different views of the meta-model: the interaction between activities and resources, the linkage between business processes and activities, the resource interdependence of entities and objects of the enterprise, the coupling between the capabilities and resources, etc. We propose to use the COBIT best practices for driving IT processes. Thus we add the abstract concept objective which will be specialized. We will also add a specialization of functional entity to model IT processes. In this work, we also offer a variety of algebraic structures to establish structural measures on the information system. For each class of structure we define its role and contribution to the governance of the information system

Towards the Control and Prevention of Waste in IT Service Operation Using Fuzzy Logic: Focus in Incident Management Process

All production lines are continuously confronted with the phenomenon of waste, especially in IT operations. A waste is assessed in terms of the required resources and the cost employed to solve the problem behind it. Eliminating the waste in daily operations is essential to improve IT service management. This article aims to provide an estimation of the level of potential waste, where waste generation trends are provoked by the activities of IT service management processes. We are going to focus particularly on the possibility of applying a Lean improvement process to IT services processes when using fuzzy logic method. We specifically demonstrate our contribution through the application of fuzzy analysis to the incident management process. This approach also aims at developing a theoretical and pragmatic model and promoting the knowledge of IT experts. In order to make our framework as generic as possible, concepts of IT operations, including the incident management, are inspired by the Information Technology Infrastructure Library (ITIL), the most prominent framework for IT service governance according to the current literature
