Um modelo formal para avaliar o valor de negócio e sua aplicação no contexto de gestão e governança de TI.

Abstract

IT investments in all business activities are in continuous expansion, along with the dependencies between IT performance and results achieved by the business it supports. The business value of IT corresponds to the set of contributions that these technologies provide organizations with to achieve their established objectives. Facing the challenge of measuring return on investment and controlling ITdependency risks, managers currently count on subjective and imprecise support to maintain the IT aligned with the organization´s business objectives. In this thesis, we present a formal model for business value that allows one to express the concept of value and its dynamics in terms of numbers, capable to provide support for management decisions and IT governance based on the value to be transferred from IT to the business. Case studies conducted in real business scenarios indicate the effectiveness of the proposed method.
