Current managers have found that strategic management is a necessity for working in the complex and chaotic environment. Strategic management is defined as the process of formulating strategy to attain long-run goals in the variable conditions. This process includes three stages: formulating, implementing, and evaluating strategy. In the first stage, two main activities are usually conducted: strategic positioning and strategy defining. This paper concentrates on the first activity; strategic positioning. There is a four- stage technique called “Delta Technique” that points out the strategic position of a special firm. Delta Technique steps are: fuzzy test of hypothesis for Delta model variables, prioritization of the accepted variables through Fuzzy Analytic Hierarchical Process, plotting radar graph for three strategies of Delta Model, and determining the strategic position in a three dimensional plot. Finally this technique is tested in the Internet Service Provider (ISP) industry of Iran.
