P-Chart & NP-Chart

For fraction or count of defectives.

C-Chart & U-Chart

For defects per unit counting.

Closed-Loop Containment

Closed-Loop Corrective Action

Close the gap between detection and correction. Connect control chart alarms directly to frontline action plans to stop defects from escaping.

01

Automated Alarm

Process deviations instantly trigger Andon lights and OCAP workflows.

02

Operator OCAP Logs

Operators log machine settings, tool adjustments, or batch shifts immediately at line-side terminals.

03

Containment Trigger

Automated quarantine ticket created in your MES to hold suspect parts.

04

5-Why Root Cause Analysis

Quality team identifies the root cause using historical sensor correlations.

05

Recalibration & Verification

Operators adjust physical processes and log corrective action proofs.

06

Cpk Recovery Auto-Check

The platform monitors the next 30 points to verify Cpk returns above 1.33.

FAQ

The questions we hear most.

Can this work with our existing systems?+

Yes. We assess your current equipment, spreadsheets, ERP, MES, and data sources first, then integrate where it creates practical value.

Do we need to replace machines or software?+

No. The implementation is designed to complement your existing operation and can start with the data and tools you already use.

How do we start?+

We begin with one defined workflow, site, or production line and agree on the operational measure that will determine pilot success.
