O objetivo dessa pesquisa é propor um modelo relacionando os investimentos em tecnologia da informação (TI), a governança da cadeia de suprimentos (GCS) e o seu desempenho. Foi realizado um estudo piloto com uma etapa qualitativa e outra quantitativa para a elaboração e o refinamento do instrumento. Na etapa qualitativa, foi elaborado um modelo baseado numa extensa revisão da literatura e em dois estudos de caso realizados em 6 grandes empresas brasileiras com relevância mundial. A partir dessa etapa, foi proposto um modelo que foi refinado através de uma etapa quantitativa com 38 executivos de grandes empresas. Foi identificado que a TI é um dos principais direcionadores da GCS, influenciando o desempenho das empresas na cadeia. O modelo final é composto por 5 constructos e 26 elementos. Nos constructos: (a) governança contratual, o elemento contrato formal emergiu das análises; (b) governança relacional, o elemento cooperação não foi confirmado; e (c) governança transacional: a transparência nas transações foi considerada como sendo um elemento importante. No constructo investimento em TI relacionado à GCS, emergiram cinco novos elementos. No constructo desempenho da cadeia relacionado com a GCS, foram destacados os aspectos de mercado como sendo relevantes. Assim, o modelo contempla elementos a serem analisados para entender como os investimentos em TI influenciam a GCS e seu desempenho.

The aim of this research is to propose a model that relates information technology (IT) investments, supply chain governance (SCG) and performance together. For this purpose, a pilot study involving both a qualitative and a quantitative stage was conducted. The qualitative analysis, consisting of an extensive literature review and two case studies conducted in six major, globally-relevant Brazilian companies, led to the development of an initial model. This model was refined during the quantitative stage that involved 38 executives from large national companies. IT was found to be one of the main drivers of SCG influencing companies' supply chain performance. The final model consists of 5 constructs and 26 elements. Regarding the SCG constructs: (a) a new element 'formal contracts', emerged in the 'contractual SCG' construct; (b) the element 'cooperation' was not confirmed in the 'relational SCG' construct; (c) the element 'transparency' was considered an important element in the 'transactional SCG' construct. Five new elements emerged in the 'IT investment' construct. Market aspects were highlighted as being relevant in the 'supply chain performance' construct. Thus, the model includes elements that can be analyzed in order to shed light on how IT investments influence SCG and supply chain performance.

Many studies have highlighted the capacity Information Technology (IT) has for generating value for organizations. Investments in IT made by organizations have increased each year. Therefore, the purpose of the present study is to analyze the IT Business Value for Information Intensive Organizations (IIO - e.g. banks, insurance companies and securities brokers). The research method consisted of a survey that used and combined the models from Weill and Broadbent (1998) and Gregor, Martin, Fernandez, Stern and Vitale (2006). Data was gathered using an adapted instrument containing 5 dimensions (Strategic, Informational, Transactional, Transformational and Infra-structure) with 27 items. The instrument was refined by employing statistical techniques such as Exploratory and Confirmatory Factorial Analysis through Structural Equations (first and second order Model Measurement). The final model is composed of four factors related to IT Business Value: Strategic, Informational, Transactional and Transformational, arranged in 15 items. The dimension Infra-structure was excluded during the model refinement process because it was discovered during interviews that managers were unable to perceive it as a distinct dimension of IT Business Value.

The aim of this study is to explore and validate the dimensions of IT Portfolio Management (ITPM) in Brazilian companies, based on three different models. Five case studies were carried out in Brazilian companies that invest more than nine million reals per year in IT. Eight top IT executives from those organizations who had knowledge of the dimensions of ITPM were interviewed. Items were modified and new items included within the dimensions, while examples of equipment or systems applicable to each of the four dimensions were also identified. Research that helps managers to better understand and structure their IT investments by using the dimensions of ITPM is important to assist in the management of such resources.
