The information Technology Portfolio Management (ITPM) is seen as one way of identifying, analyzing, justifying and managing investments in Information Technology (IT). Accordingly, the main objective is to analyze IT management of manufactures and identify how ITPM, in four dimensions (strategy, informational, transactional and infrastructure), could help this issue. For this purpose, three case studies were developed. The IT manager from each firm was interviewed with the aid of semistructured instrument. The preliminary results indicate that infrastructure receives the largest part of the investments and that IT manager have difficulty defining the percentage of investments in IT in the proposed dimensions. Despite this difficulty, the interviewees recommended the use of the ITPM technique.
