Governance and Management of Information Technology: Decomposing the Enterprise in Modular Building Blocks Based on Enterprise Architecture and Business Oriented Services

Abstract

This chapter aims to present a proposal for a model that supports organizational governance through the alignment of business with Information Technology - IT. Firstly, it was observed that there are some paradigms which limit the use of enterprise architectures and hinder governance functions. Secondly, it focuses on the IT unit, where IT systems and subsystems are interrelated and the performance levels of the organization are aggregated, creating a macro-structure system capable of supporting corporate governance and IT. Finally, the IBM`s Component Business Model - CBM® was applied to represent relationships of the IT unit with the organization, through decomposing the organization into business components that supply and demand services to facilitate their governance and management.
