I feel quality control is essential for producing quality services and products. Quality Control builds processes that reduce defects and errors. I feel quality control is about preventing defects and errors rather than reducing error by inspection. For example six sigma is about building process and statistical controls to monitor these process reducing error and defect. I feel that quality control is about continuous improvement. Quality Control is not a one time event but an on going event over time. I feel that all employees must engage in the quality control effort. Standard operating procedures helps employees adhere to operating standards. I feel when a defect is discovered find the root cause of the defect is critical. Discovering the root causes helps prevent future defects. Getting to the root cause is often discovered by asking five why questions. This technique helps get through the layers to find the real issue. Analyzing defects often reveals weaknesses in existing processes. The team learns through the process of discovering root cause.
