Statistical Quality Control (SQC)
The general category of statistical tools used to evaluate organizational quality
descriptive
... [Show More] statistics
Statistics used to describe quality characteristics and relationships
Statistical Process Control (SPC)
A statistical tool that involves inspecting a random sample of the output from a process and deciding whether the process is producing products with characteristics that fall within a predetermined range
Acceptance sampling
The process of randomly inspecting a sample of goods and deciding whether to accept the entire lot based on the results
Common causes of variation
the purely random, unidentifiable sources of variation that are unavoidable with the current process
Assignable causes of variation
any variation-causing factors that can be identified and eliminated
Process Capability
The ability of a production process to meet or exceed preset specifications
Product specifications
Preset ranges of acceptable quality characteristics
Process Capability Index
An index used to measure process capability
Cp=1
process variability just meets specifications
Cp<1
process variability is outside the range of specification
Cp>1
process variability is tighter than specifications and the process exceeds minimal capability
Six Sigma quality
A high level of quality associated with approximately 3.4 defective parts per million
Define
Step 1: quality problem of the process
Measure
Step 2: current performance of the process
Analyze
Step 3: process to identify root causes of the quality problem
Improve
Step 4: process by eliminating the root causes of the problem
Control
Step 5: process to ensure improvements continue
