Overview

What this service does.

Most "audits" are sales calls in disguise. Ours are not. We don't sell IS machines, furnaces, or inspection equipment. We walk your hot end, read your data, talk to your crews, and hand you a punch list ranked by EBITDA impact.

Benefits

FAQ

Questions, answered.

No. Lean Glass is vendor-neutral. We have no equipment to sell, no OEM partnerships, no commissions. Our findings are operational, not commercial.

Yes. Every engagement runs under your NDA and we align with your safety and data policies before we set foot on site.

Most plants see measurable movement on defect rate and jam-ups within 30 days. Full stabilisation depends on how many shifts adopt the new standards.
