Statistical Process Control
Monitor your process in real time and catch drift early.
SPC monitors your process with 7 control-chart types so you can separate natural variation from special causes and catch problems early.
What you gain with QUALIX
- 7 control charts automatically; limits and Western Electric rule violations are flagged instantly.
- Real-time monitoring and alarms — you're warned the moment drift appears.
- Instant Cp/Cpk as data is entered; historical trend is retained.
- No more updating spreadsheet charts or juggling scattered files.
How it works
Bring your process under statistical control — from data entry to control charts and process capability.
-
1
Create a chart
Enter your company and choose the chart type; start from scratch or try ready sample data.
-
2
Enter the data
Set subgroup count and size and enter the readings; add lower/upper spec limits and process capability is computed automatically too.
-
3
See the control chart
The centre line and UCL/LCL control limits are computed automatically; out-of-control signals are detected with the 8 Nelson rules and marked on the chart.
-
4
Measure process capability
Cp, Cpk, Pp and Ppk indices are computed with a histogram and normal curve; capable/not-capable is judged automatically and the result is exported as PDF/CSV.
Screens are shown with sample company data.
Purpose
To keep the process in control, reduce variation and time interventions correctly — distinguishing over-adjustment from real drift.
