Explain how just-in-time processes relate to the quality of an organization's outputs.
JIT reduces costs of quality by lowering waste and scrap. JIT improves quality by shortening the time between error detection and error correction. Meanwhile, better quality means less inventory and a better JIT system.
What is the quality loss function (QLF)?
The quality loss function identifies all costs connected with poor quality and shows how these costs increase as the product quality moves away from being exactly what the customer wants.
Identify the ten determinants of service quality. Describe two of them in a sentence or two each.
The ten are reliability, responsiveness, competence, access, courtesy, communication, credibility, security, understanding/knowing the customer, and tangibles. Descriptions are found in Table 6.5. Here are two examples: Access involves approachability and ease of contact. Security is the freedom from danger, risk, or doubt.
Security is the determinant of service quality that means freedom from danger, risk, or doubt.

What is a poka-yoke? Give an example.
Literally translated "foolproof," a poka-yoke is a foolproof device or technique that ensures production of good units every time. Examples will vary, but include McDonald's french fry scoop and standard sized bags used to ensure the correct quantity, and prepackaged surgical coverings that contain exactly the items needed for a medical procedure.
