Technological efficiency is one of the key-stone notions in mechanical engineering, which defines structural features and cost of manufacturing and operation of a product. It is currently generally recognized that technological efficiency is advisable to be tried out at the phase of design study. This allows comparing different variants at the stage of selection of a structure, operating principle and design of a product. At the same time, technological efficiency maintenance yet remains the least formalized task in engineering, which is handled heuristically and depends on personnel skills. This situation is out of keeping with the production standards as it leads to extra expenditures and impedes introduction of advanced equipment. This problem can be solved within the methodology of concurrent engineering. The article discusses the methodology of technological efficiency maintenance in concurrent engineering. The implementation of the methodology is described in terms of products of industry. Different approaches to maintaining technological efficiency are compared. The technological efficiency assessment procedure is presented. The applicability of the procedure at the stage of preproduction model manufacture is estimated. The argumentation is given for the expediency of integrated product design and production engineering toward maintenance of technological efficiency. Capacities and application of foreign procedures are argued. The integration of technological efficiency procedures and CAD-systems is validated. The scope of the review encompasses the domestic and foreign software in the sphere of technological efficiency. The technical and economic aspects of technological efficiency tryout are discussed.
