Systemic approach for optimizing information technology resource as a contribution of information system governance

<p> Information technology (IT) resource management is considered as one of the main pillars of Information System (IS) governance in the company. In this article, we propose a systemic approach from the structural paradigm based essentially on the formal extension of the ISO 19440 Meta-model. This structure contains specific constructs from the Cobit framework and system tools as the Galois lattices, likely to bring a better vision of the use of IT resource in the company. This technique allows a systemic analysis applied to special structural matrices to evaluate the deployment mode of IT resource to achieve business processes. Such approach allows a good optimization of IT resource as a pragmatic and effective contribution to Information System governance.</p>
