Abstract. One of the significant factors in failures of applying technology in attaining competitive advantage of developing countries firms is the lack of knowledge of the level of technological capabilities of the firm and the lack of using competencies to achieve relative advantages. The evaluation of technologic requirements is an instrument which is utilized in order to determine the needed requirements for the implementation of technological proprieties. The assessment of technological requirements not only identifies the weak and problematic fields of the firm but also highlights and determines its relative advantages. By utilizing the model of assessing technological requirements, in the present paper, we attempt to cast light upon the level of technological competencies of Yasan Steel Structure Company. This model evaluates the capability level of the firm from nine dimensions and in each status,  it determines the condition of the firms. Besides, it provides some suggestions to reduce the existing gap.
