For many small companies, or any company with only a small SPC need, a true SPC software package can seem unnecessarily expensive. This application allows you to track up to three individual variables at no cost and multiple versions of the file can be created for more variables.
The program allows you to log the data along with associated notes, and it visually identifies any OOC points at both the data entry field and in the automatically created control charts. In addition to the three-standard deviation violation, it also identifies eight rules in total including trends, three different runs, over-control, stratification, and mixture violation. The user can control which rules are applied along with the number of points displayed on the control charts.
If you’d like more variables accommodated in one file, or any other customization, please contact me.
