Availability can look healthy while customers remember a failure differently.

Mariana Campos · Seasonal online shopper

A shopper who encountered a checkout disruption during a high-demand promotion and later hesitates to try again.

What pulls against what

  • uptime metrics vs customer memory
  • fast standardization vs product-specific learning
  • broad hypotheses vs safe experiments

What is at stake

The wrong reliability target can create impressive recovery metrics without protecting repeat confidence. A focused learning loop can reveal what to defend first

Why Affirm

At Affirm, these distinctions can matter when short checkout interruptions shape future willingness to use a payment plan.
