Overview

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.
