The problem: shifts spotted too late
A process can drift before any single batch fails. Without control charts and run rules, the shift only shows up once batches start failing.
Each batch can be within spec while the process slowly moves toward a limit. Looking at batches one at a time, nobody notices until a batch fails.
What this demo shows
- Plot every batch.
- Turn the plot into a control chart.
- Let standard SPC run rules flag the shift.
- Trace it back to a raw material lot.
Why it matters
Don't wait for a report to discover a process drifting out of control. Control charts with standard run rules flag a shift while there's still time to correct it.
Tracing the shift to the lots used turns a statistical signal into a cause the team can act on, such as a raw material lot change.

Uncountable is one platform for R&D, quality, and the product life cycle. In explore data, plot viscosity for 30 batches of a satin enamel in batch order, straight from the quality record. Spec limits, control limits, and capability land on one chart with CPK, CPL, CPU, and PP in the legend. CPK reads 0.58 and PP 0.624 against a spec of 95 to 105.
Run rules show why. Two run rules flag the shift, and the violations table names the batches. So, what changed in the batches above spec? The batch records point to a lot. The three batches above spec all used thickener lot R5521. Control charts, capability, run rules, and lots all from the same quality record with no export.
See how Uncountable connects quality, R&D, and the product record.
