Outline the steps in the design of a quality control system

Outline the steps in the design of a quality control system. These steps can be found in narrative form within section 9.1 of your textbook. Discuss how the steps can lead to higher efficiency in an organization.

Solution

Design of Quality Control Systems

-Break down production process into subprocesses and “internal customers.”
-Identify “Critical points” where inspection or measurement should take place
-Four steps in designing QC systems.

Steps in Designing QC Systems

1. Identify critical points

-Incoming materials & services
-Work in process
-Finished product or service

2. Decide on the type of measurement
-Variables (continuous scale, diameter, weight, tensile strength)
-Attribute (number of defect per unit)

3. Decide on the amount of inspection to be used.
-Sample size

4. Decide who should do the inspection
-Worker inspection or outside inspection
