SAS/QC software, a component of the SAS System, provides a comprehensive set of tools for statistical quality improvement. You can use these tools to
organize quality improvement efforts
design industrial experiments for product and process improvement
apply Taguchi methods for quality engineering
establish statistical control of a process
maintain statistical control and reduce variation
analyze process capability
develop and evaluate acceptance sampling plans
There are two types of tools in SAS/QC software: interfaces and procedures.
The interfaces are complete, full-screen-oriented environments for statistical quality-improvement applications. Unlike with the procedures, using the interfaces requires no knowledge of SAS programming. These include the SQC menu system and the ADX interfaces for statistical quality-control applications.
The procedures in SAS/QC software offer greater flexibility and power than the interface. To use a procedure, you must have a basic knowledge of the SAS language and the syntax of the procedure.
