Defect Classification
Meaning ~ System for grouping product errors into severity levels that define if a batch is accepted, reworked, or scrapped based on risk and contract limits.
Visual Limit Board
Meaning
Display panels placed on the factory floor show physical examples of acceptable and unacceptable product variations. This tool, known as a visual limit board, guides inspectors by defining the boundary of cosmetic defects such as scratches and color shifts. It does not replace engineering drawings but clarifies subjective quality standards.
Reference Standard
Production areas use these boards to align the judgment of different inspectors across all shifts. Having a visual limit board prevents the rejection of good parts and the acceptance of bad ones due to personal bias. This consistency is critical for maintaining a steady flow of finished goods.
Operational Maintenance
Quality engineers update the board with fresh samples whenever the design or material specifications change. Keeping the visual limit board accurate requires protecting the mounted samples from dust, fading, or damage. This protection ensures that the reference remains reliable over the entire production run, which prevents disputes between the quality manager and the production lead.
Commercial Value
Buying contracts often refer to these boards to settle disputes over cosmetic quality during final audits. If a buyer rejects a batch for minor scratches, the supplier can use the visual limit board to show that the parts match the approved limits. This reduces the risk of unnecessary rework and shipping delays.
