Quality Management: Product and Service Quality Improvement

Discrete data, where the number of occurrences per unit of product can be counted.

It emphasizes the importance of quality responsibility across different departments and levels of an organization.

By focusing on defect prevention through design, procurement, production, and quality assurance processes.

To evaluate the effectiveness of quality improvement initiatives and identify areas for further improvement.

By enabling the monitoring and control of processes, and identifying opportunities for process improvement and defect reduction.

The primary objective of the Taguchi Loss Function is to minimize the loss incurred by the customer and society due to variations in quality, whereas the traditional cost function focuses on minimizing the cost of defects and rework.

The 6 Sigma level of process capability has a much lower defect rate (1.7 ppm) compared to the 3 Sigma level (1350 ppm), indicating a much higher level of process reliability and quality.

Process variability is the natural variability in a process, and it is compared to the specifications established by engineering design or customer requirements to determine process capability, which is the degree to which the process variability meets the specifications.

The primary objective of quality appraisal is to evaluate the quality of a product or service, and it provides feedback to quality control and quality improvement efforts, enabling the identification of opportunities for improvement.

Mistake-proofing or poka yoke is the use of process or design features to prevent errors or their negative impact, and it contributes to quality improvement by reducing the likelihood of defects and improving process reliability.

Process capability has a direct impact on the cost of quality, as high process capability reduces the cost of defects and rework, while low process capability increases the cost of quality, and it is a critical factor in quality improvement efforts.

The inspection approach focuses on finding and correcting defects before reaching the market, whereas the strategic approach focuses on preventing mistakes from occurring and emphasizes quality at no cost.

He is known as the 'Father of statistical quality control'.

The Taguchi loss function is a mathematical function that measures the economic loss associated with a product or service's deviation from its target specification, and is used to optimize quality and reduce defects.

Process control charts are used to monitor and control processes to ensure that they operate within predetermined limits, and to detect and correct deviations from these limits.

The purpose of quality appraisal is to evaluate the quality of a product or service and to identify opportunities for improvement.

The primary goal of defect prevention is to prevent defects from occurring in the first place, rather than detecting and correcting them after they have occurred.
