Product Affinity

Overview

• Product Affinity analyses eligible baskets and Product pairs using order support, directional confidence, lift, and attach rate.
• Summary includes Orders, Items per order, Single-item rate, and Modifier attach rate.
• A minimum number of report Orders and pair-support threshold is required before pairs are shown.
• Gift cards, prepaid vouchers, and unmapped items are excluded from eligible pair analysis.
• The full eligible basket is used once per order rather than prorating Product quantities across split payments.

When to use this

• Use affinity for bundle/upsell ideas, menu placement, and staff prompts—then validate with real operational judgement.

Step-by-step

1. Choose a sufficiently long period.
2. Start with pairs that have meaningful Order support.
3. Compare directional confidence A→B and B→A.
4. Use Lift to distinguish genuine association from two independently popular Products.
5. Test an upsell/bundle before making a permanent menu change.

Common mistakes

• Do not rank a pair from tiny support above a well-supported pattern.
• Do not interpret correlation as proof one Product causes purchase of another.
• Do not include Gift Card/prepaid voucher behaviour in food attachment conclusions.

Troubleshooting

• If no pairs appear, increase the period or reduce the supported minimum pair threshold within the UI's intended range.
• If expected Products are absent, verify they are eligible mapped Product lines.
