In the article, I have discussed the goals, types of control and main directions of measures to ensure technological discipline in organizations in the production of technically complex products. The main directions for improving the performance of technological discipline were given. That are: standardization of processes in the organization, implementation of CALS technologies and processes, TQM concept that ensure the stability of the technology. I pay special attention to violations of technological discipline, they come in three categories — related to noncompliance with technological processes, noncompliance with requirements for their quality and production culture. According to the results of the inspections, appropriate measures are developed without fail. To calculate the level of technological discipline at the enterprise, I propose a simple mathematical formula. The indicator of the level of technological discipline determinated by it should be at least 97 %, which will ensure the achievement of optimal values of key performance indicators.
