Strategic decision-making is seen as an important area of research where the theory, methods and technologies can bring in a great deal of benefit to the whole enterprise at the executive level. The study of information requirements for decision-making reveals that the level of detail, granularity, format of presentation, and broad range of information type are unique for the applications at the strategic level. The provision of relevant information involves articulation of requirements based on the decision problems described by the executive manager. This paper presents the MITAIS approach that allows the user to describe a decision problem interactively and assists articulation of the problem into a presentation in a decision space, by prompting possible patterns of decision dimensions. It further aids a configuration of information requirements into an information space, which covers the information required for the described problem. A case study has been conducted using this approach to the use of the set of techniques of MITAIS.
