SIX SIGMA METHODOLOGY: A POSSIBLE SOLUTION TO INCREASE THE PROCESS CAPABILITY IN THE AUTOMOTIVE MARKET

摘要

The purpose of this paper is to show the power of the Six Sigma methodology in satisfying the requirements of the automotive market. The company of this project produces cooling air pipes for deluxe vehicles. The problem solving method applied was the DMAIC (Define, Measure, Analyse, Improve, Control). This process review takes into account the increased quality standards of the output; therefore, the real problem was not to increase the system productivity, but to eliminate those process features that the automotive market considers as defects. For example, identifying the CTC (Critical to Customer), the main defect categories were: scraps on the pipes, blows on the devices and contamination of chip. The paper shows all steps of the Six Sigma implementation suggesting the solution to increase the process performance.
