Statistical Process Control

Quality engineers monitor dozens of critical-to-quality parameters across multiple product families, but SPC control charts are reviewed reactively - often after a batch has already been scrapped or a customer complaint has been filed. Cp/Cpk reports are generated weekly in spreadsheets, making it impossible to detect drift in real time or trace a specification breach back to the machine, material lot, or operator shift that caused it.

How It Works

Monitor Cp/Cpk indices, control chart violations, and out-of-spec trends conversationally. Ask which parameters are drifting, predict specification breaches, and trace variation back to specific machines or material lots.

Instant Analysis

Drag and drop your CSVs. No complex pipelines required.

Which parameters are drifting toward spec on Product Family A?

Three CTQ parameters on Family A have Cpk below 1.33; fill weight is the worst at Cpk 0.94 and has drifted 0.6 sigma toward the lower spec limit over the past 11 days, all of it on Machine 7 running material lot RM-4471. At the current drift rate it breaches the LSL in about 5 days, so recalibrate Machine 7 and quarantine the remaining RM-4471 lot now.
