GMS 401 STUDY GUIDE 2025/2026 QUESTIONS WITH
ANSWERS RATED A+
✔✔Just-in-time services - ✔✔designed to produce or deliver goods just as they are
needed
✔✔Quality Robust - ✔✔products that are consistently built to meet customer needs in
spite of adverse conditions in the production process
✔✔Target Oriented Quality - ✔✔a philosophy of continuous improvement to bring a
product exactly on target
✔✔7 tools for TQM - ✔✔Tools for Generating Ideas
-->Check Sheet
--> Scatter Diagram
--> Cause-and-Effect Diagram
Tools to Organize Data
--> Pareto Chart
--> Flowchart (Process Diagram)
Tools for Identifying Problems
--> Histogram
--> Statistical Process Control Chart
✔✔Cause-and-effect Diagram - ✔✔a schematic technique used to discover possible
locations of quality problems
✔✔4 possible "causes" of quality problems - ✔✔Material, Machinery, Manpower, and
Methods
✔✔Pareto Charts - ✔✔graphics that identify the few critical items as opposed to many
less important ones
✔✔Flowcharts - ✔✔block diagrams that graphically describe a process or system
✔✔Statistical Process Control (SPC) - ✔✔a process used to monitor standards, make
measurements, and take corrective action as a product or service is being produced
✔✔Control Charts - ✔✔graphic presentations of process data over time, with
predetermined control limits
✔✔Statistical Process Control (SPC) - ✔✔a process used to monitor standards, make
measurements, and take corrective action as a product or service is being produced
, ✔✔Inspection - ✔✔A means of ensuring that an operation is producing at the quality
level expected
✔✔Source Inspection - ✔✔controlling or monitoring at the point of production or
purchase - at the source
✔✔Poka-Yoke - ✔✔Literally translated, "foolproof"; it has come to mean a device or
technique that ensures the production of a good unit every time.
✔✔attribute inspection - ✔✔an inspection that classifies items as being either good or
defective
✔✔Variable Inspection - ✔✔classifications of inspected items as falling on a continuum
scale, such as dimension or strength
✔✔Determinants of Service Quality - ✔✔reliability, responsiveness, competence,
access, courtesy, communication, credibility, security, understanding/knowing the
customer, tangibles
✔✔A process is said to be operating in statistical control when: - ✔✔the only source of
variation is common (natural) causes.
✔✔The objective of a process control system - ✔✔is to provide a statistical signal when
assignable causes of variation are present.
✔✔Natural Variation - ✔✔variability that affects every production process to some
degree and is to be expected; also known as common cause
✔✔When natural variations form a normal distribution, they are characterized by 2
perimeters - ✔✔1. Mean (the measure of central tendency, or average)
2. Standard Deviation (the measure of dispersion)
*as long as the distribution (output measurements) remain within specified limits, the
process is said to be in control, and natural variations are tolerated.
✔✔Assignable Variation - ✔✔variation in a production process that can be traced to
specific causes
✔✔x -chart (x-bar chart) - ✔✔a quality control chart for variables that indicates when
changes occur in the central tendency of a production process.
✔✔R-chart - ✔✔a control chart that tracks the "range" within a sample; it indicates that
a gain or loss in uniformity has occurred in dispersion of a production process
