MGT 366 – Exam #3 Study Guide Chapter 10 – Quality Control Key Ideas 1. Random versus Assignable Variation. Random variation is the variation that is natural to any process, and is present when the process is in control. Assignable variation is any variation that can be traced back to a particular cause. Recognizing assignable variation is the key to recognizing when a process is out of control. 2. Attributes versus Variables. There are two principal types of quality data: attributes (counting the number of occurrences in one or two categories) and variables (measuring a characteristic or the deviation from a standard). 3. Acceptance Sampling versus Process Control. There are two principal types of Quality Assurance: sampling inspection of incoming and outgoing materials (acceptance sampling) and control charts for ongoing processes (process control). 4. Control Charts. Control charts differentiate between the process being in control (within an accept range of random variation) and out of control (outside the acceptable range). Process control involves making frequent small sample inspections to detect whether the process in control or out of control. Out of control means either above the upper control limit below the lower control limit. The limits for control charts are established first by obtaining 20 to 25 small samples of same size at different times from the process. This forms the basis for judging future samples. 5.
