How we got there

01

The Challenge

MedTech manufactured Class II medical devices under strict FDA regulations. Manual quality inspection was slow and subjective with paper records. Spreadsheet-based SPC couldn't detect real-time trends. 4.2% defect rate was unacceptable for medical devices.

02

Our Approach

Built custom platform (React + Node.js + TimescaleDB) integrated with inspection equipment. Dashboard showed real-time SPC charts for 250+ quality parameters. ML models detected anomalies and predicted out-of-spec conditions.

03

The Results

Quality dashboard transformed manufacturing from reactive to predictive. Real-time SPC detected process drift before defects occurred, reducing scrap from 4.2% to 0.67%. Automated documentation ensured FDA traceability. Root cause analysis cut MTTR from 18 hours to 2.5 hours. Achieved Six Sigma certification.

Real-Time SPC Monitoring

Automated data from measurement equipment updated SPC charts every 30 seconds. ±3 sigma control limits detected approaching out-of-control conditions. Western Electric rules identified patterns indicating process drift. Operators received instant alerts for adjustments before producing defects. First-pass yield improved from 95.8% to 99.33%.
