The paper is aimed at measuring innovation and qualification of technological operations in automotive production within the quality management system. Quality requirements according to ISO/TS 16949 promote a process approach for the design and development, production, installation and servicing of automotive products, which can result in increased quality, reduced variation and increase of efficiency. The solution focuses on the process of approval of parts in series production (Production Part Approval Process – PPAP). The PPAP purpose is to determine whether an organization properly understood all customer requirements listed in the specifications and records of the technical design of the product. PPAP further verifies that the process has the potential to produce a product in series production so that customer requirements will be met, in actual production volume and at the agreed rate of production. Specifically, a toothed winch of hydroelectric generator is solved by the case study.
