Returns reason codes and root causes: using returns data to prevent returns
Design reason codes that people can apply consistently, record the customer's stated reason separately from what inspection found, rank causes with a Pareto chart and with rates that state their denominator, route each cause to the team that can fix it, and check that a fix worked by comparing like with like.

Skills you'll practise
- Record a return's stated reason and inspected finding as separate facts using a clear code list
- Spot problems in a reason-code list (overlap, vague codes, an uncontrolled 'other') and propose fixes
- Rank return causes with a Pareto chart and with return rates that state their denominator
- Route a cause (picking, packing, carrier, product, listing) to the owner who can change it, with evidence
- Check whether a change reduced returns by comparing rates over comparable periods
