STUDY OF THE CAUSES OF PLANNING FAILURES.

The authors explain their hypothesis describing the planning behavior of an individual and an organization, which they have postulated elsewhere, in reference with the model of so called ″rational″ decision-making, as well as seven dimensions to be considered when evaluating each planning alternative. Of eight possible causes of planning failures obtained from the model, the ambiguity in the utility functions, the wrong forecast of the alternatives, and the wrong forecast of planning alternatives are identified as important and crucial. Some supplementary considerations on the above identified causes, as well as brief discussion on the relation between the status of the model and this study follow.
