Management Of Ict-Based Enterprises - Approach Through Frameworks For Business Architecture, It Governance And It Management

Many organisational systems today rely heavily on well-developed information and communication technology featured in more or less complex information systems and their related systems with other specifi c purposes. Managing those systems requires well-defined methodological frameworks in order to ensure the realisation of strategic goals, planning and organization, delivery and support of their services as well as monitoring and evaluation of their processes. Frameworks, which are now widely accepted, began as a collection of best practices and “methodological frameworks” and sometimes as ontologies in specific areas of enterprise, to become frameworks which profoundly decompose the dynamics of an enterprise by enabling effective implementation and exploitation of the IT. This paper presents some of the current (meta)models and methodology frameworks and their suitability for governance and managing business strategy, process and operations, change, IT strategy, information and technology balance sheet, risk conformance and compliance. Frameworks and their models methods and tools that are compared include CoBIT, ITIL, TOGAF, ISO 27002 and Deloitte framework.
