Coating Complaints by Batch and Installer: Use Both Views before Assigning Cause

Review coating complaints by both production batch and installer, using exposure and job counts to avoid misleading raw totals.

Updated · NANOLAB Knowledge

A cluster of complaints can follow a product batch, an installer or a shared application condition. Looking through only one of those views may send an investigation in the wrong direction.

Build a linked record

For each case, record batch, product version, installer, substrate, application date, preparation and reported issue. Use consistent complaint categories and distinguish confirmed findings from customer descriptions.

Include the denominator

Ten complaints from an installer handling a thousand jobs differ from ten complaints across twenty jobs. Similarly, batch counts need the amount or number of jobs distributed, where that information is reliable. Report missing exposure data rather than presenting raw counts as failure rates.

Cross-tabulate before assigning cause

Pattern Useful next question
One batch, several installers What product or distribution factors are shared?
Several batches, one installer What local process or exposure factors recur?
One substrate across both Is the use case the common factor?

Investigate representative cases

A pattern directs sampling; it does not prove causation. Check retained samples, application records and comparable successful jobs. Avoid excluding inconvenient cases merely because they weaken the initial explanation. Record the evidence needed to close each hypothesis and verify any corrective action under the conditions that produced the complaint.
