One of the most important problems in the industry is lack of competitiveness, because of transparency is very poor. In the other words, information is not enough for decision making. Then transactions don't have good efficiency. If we have a lot of suitable, on time and relative information, customers buy optimal alternative and on the other hand manufacturers try to keep their market share. This problem, lack of transparency, is a big problem in the informatics companies. Then a project, entitled ranking of informatics companies, was defined. In this paper, we searched the literature of ranking in the world, techniques and methodologies of ranking, and models of organization diagnosis. Result of this paper, was designing a model for ranking informatics companies, rank based on three fields of input, process, and output. Then we generate a quantitative technique for measuring informatics companies' score. And at last, we ranked informatics companies.
