How this supplier actually performs

Late percentage, average days late, share of orders with something short or damaged, and how many claims are still unsettled — all counted from records the builder already made.

What it is

A scorecard on the supplier's card, computed from delivered orders and claims. Lateness is measured against the FIRST promised date, not the last revised one. Exceptions count the share of orders that produced a shortage or damage claim. Nothing is self-reported and nothing is entered by hand.

The Reliability block on the supplier header: 'Late 34% · avg 9d | Short or damaged 18% | 2 claims unsettled', the first two in red. SupplierDetailPanel.tsx. Sample data — no customer information appears here.
How it works
  1. 1computeReliability walks delivered orders and compares delivered_at against original_expected (falling back to expected_delivery)
  2. 2Shortage and damage claim order ids are collected into sets and unioned for the exception rate
  3. 3Late above 25% and exceptions above 15% render in the breached colour
  4. 4Unsettled claims are counted as open, sent or acknowledged
  5. 5The panel only appears once there is at least one delivered order to count
Why we built it

The comment in the panel says what it is for: 'How this supplier actually performs — counted from deliveries and claims the builder already recorded, never self-reported. This is the number that changes who you buy from next time.' It only works because the first promised date is preserved (migration 217) and because the three dates are kept distinct (migration 220).

The problem
  • Supplier performance is a feeling rather than a number
  • The evidence for a hard conversation does not exist
