The concept of strategy and strategy formation can be analyzed from different perspectives. Mintzberg (1990) has identified ten basic schools of thought in relation to this topic. The strategy is conceived as a process of vision, design, planning or positioning; as a process of knowledge or learning, subject to political, cultural or environmental influences, or more properly as a process focused on transformation. Over the years, information systems have come to play an increasingly strategic role in business, capable of supporting the formulation and implementation of strategies and, particularly, the reformulation of strategies. This paper offers a review of the literature on the subject and relates the information systems with the ten mentioned schools of strategy, allowing the discussion of the usefulness of the different types of information systems.
