Reviewing a leather care mistake: find the first wrong decision

Trace the earliest error in assessment, testing, product choice, technique or communication rather than focusing only on the final step.

A useful review identifies the first mistaken decision, not just the last visible failure.

Questions to ask

Was the original assessment supported by enough evidence?
Were the test location and observation time appropriate?
Were too many variables changed together?
Did treatment stop promptly when a problem appeared?

Review sequence

Reconstruct the timeline.
Separate immediate causes from underlying process problems.
Define improvements that can be checked.
Update the checklist and arrange targeted retraining.

Do not conceal failures or look for a scapegoat. Where a customer's property is involved, prioritise transparent communication and responsible resolution.
