Map each interval
Identify the time from order receipt to evaluation, from evaluation to approval, from approval to provider processing, and from processing to customer notification. Include non-business days and peak periods where relevant.
Define pending and delayed states
A customer should know whether the order is still under review, whether action is needed, and when to contact support. Internal monitoring should distinguish expected waiting from an actual failure.
Measure timing by cohort
Report median and tail timing by campaign and decision state rather than one overall average. Investigate delays that cluster around particular Shopify order conditions or handoffs.
