Abstract
This study focuses on the evaluation of process capability in the production of bumper according to regulation defined by ISO 9001:2015 Quality Management Systems. Requirements and ISO/TS 16949:2009 Technical Specification.Therefore, statistical process control is analysed on the basis of normality and stability of the process, and process capability indices Cp and Cpk are calculated. The values obtained for indices are Cp = 1.084 and Cpk = 0.972. Therefore, we can consider the process as incapable and it is necessary to find significant causes which influence the process. After aplication of corrective action were calculated the process capability indices Cp and Cpk again and obtained values Cp = 4.034 and Cpk = 3.820 show that the process is influenced by random causes only and is capable.
