Evaluate defect rates, scrap percentages, and root causes across profile series
What this does
Identifies recurring quality defect patterns (e.g. 70% of rework caused by corner crimp misalignment) using Pareto distribution charts to prioritize preventive actions.
Before you start
- Non-Conformance Reports (NCR) recorded.
Steps



Important
Tracking scrap rates by extrusion supplier reveals whether material defects are caused by supplier alloy imperfections or internal saw operator handling.
-
01
Open Production › Reporting › Quality (NCRs).
-
02
Review the monthly breakdown of defect occurrences by root cause category.
-
03
Analyze scrap financial losses grouped by raw extrusion supplier and profile series.
-
04
Export quality trends to present during monthly plant operations management meetings.
Common mistakes
- Treating scrap costs as standard overhead without holding responsible work centers accountable.
- Failing to track glass breakage rates during crane offloading and tempering transport.
