Stored Procedures are executable scripts used with database applications such as MS SQL Server and Oracle to perform complex operations. Often, a Stored Procedure is the most efficient and effective method of manipulating data in complex databases in preparation for supplying it to external applications like NWA Quality Analyst.

NWA Quality Monitor Workstation can be configured to operate in a variety of network environments.

When looking in the Quality Monitor manual for guidance on setting up help files for use by the data-entry operator in Quality Monitor, the designer is invariably pointed to the built-in help system. While this system works well, it is only capable of displaying rich-text files and NWA’s own help file format (created by the QM help file editor). In fact, if you look beyond the built-in help system, the designer can use just about any type of document, if you plan ahead.

SPC charts that show limited descriptions on the X-axis (some SPC packages only show the data row) are missing key information that is needed to clearly identify potential sources of excessive variation and reveal relationships. Including as much descriptive information as possible makes chart interpretation easier and more accurate. Something as simple as adding axis labels can transform your SPC charts into effective tools for solving problems and improving processes.
