One of the important aspects of providing the high level of the enterprises competitiveness on the market is existence of the necessary level of IT-readiness. By using the term "IT-readiness" we mean the ability of the enterprise to reach the mission by the most effective use of modern information technologies. There are contradictions between the need of the enterprise operatively to reconstruct design and production structures accordingly to the market condition change and the level of the modern IT use for maintenance of science intensive samples creation projects. The problem situation becomes complicated because of the lack of possibility of the fast development of expensive information support systems through the absence of big financial resources for the machine building enterprises in the conditions of an unstable investment climate and a low level of profitability. It leads to the need of the stage-by-stage IT introduction in the course of a life cycle support of a new equipment creation project that is also a characteristic for the machine building enterprises. It turned out that the high technology development is carried out now under the conditions of essential restrictions of financial resources all around the world. In these conditions one of progressive ideologies is Lean Manufacturing methodology. World experience shows that the success of this ideology introduction is directly connected with an effective use of modern information technologies of the high technology samples design and business management. Thus, an important question is the compliance of the enterprise to the necessary level of IT-readiness which is directly connected with a technological maturity.
