Quality Control

Toyota is a company at the forefront of automotive and engineering innovation and quality. Quality control charts are used by Toyota but in a different manner. Since quality control receives most of the attention because of its statistical nature and the odds of error in sampling sizes are far too great to risk Quality Control is “built into the process”. That is to say that Quality Control can be assured only when it is built into the process and when said inspection provides immediate and accurate feedback at the source of the defect. Thus newer methods were added on to Quality Control that required and emphasis on inspection be it self inspection or more progressively Successive Inspection. Self-Inspection allows for the most instantaneous feedback but it is flawed; unintentional errors are compromise judgments due to work loads are presented. More effectiveness in QC lies within Successive Inspection where workers inspect products passed along from a previous operation before processing them themselves. This method improves prior methods but Toyota has aided by “enhancing” the S.I. method by providing systems and devices that allow for immediate and efficient defect detection. The Quality Control now becomes utmost reliant on Enhanced Successive Inspection in the plant itself but Toyota does not rest in the field of QC. Management sends out Q.C. agents to detect errors at the Source; Vertical and Horizontal Source Detection. Toyota possesses a penchant of trust for their employees and relies heavily on a trained and intelligent workforce. The Six Sigma practice is apparent as the company has a huge philosophy on detection and prevention of errors limiting it to the 99.999991%.
