About strategic planning of information technologies development in corporation

Existing methods of corporate IT-strategy development are based on the requirements that must be described in the company’s business-strategy, but often formal businessstrategy is not available. In this paper we solve the problem of creation a pattern of strategic behavior of IT-division in large corporation in the absence of a formal businessstrategy. The general process of decision making in a corporation is described, a model of strategic decision-making about the development of IT is proposed. The proposed model allows determining the level of complexity of IT initiatives implementation on the basis of their impact on transformational and transactional costs. The level of complexity, in turn, imposes restrictions on the use of the various elements of enterprise architecture. A method for making strategic decisions based on this model is developed. Usage of this method by creating a virtual design environment for manufacturing corporation involved as a collaborator in the new product development is demonstrated.
