Purchase-friction triage
Reproduce an intermittent storefront failure and narrow it to a browser, state, component, service, or configuration.
Run this triage for intermittent add-to-cart, cart, form, checkout-navigation, or storefront failures that do not cause a full outage.
Inputs
- Affected URL and journey
- Error message or observed behavior
- Browser, device, market, and time window
- Product or variant
- Recent release or configuration changes
- Approved test-environment details
Output
- Reproduction matrix
- Raw observations and suspected cause in separate fields
- Likely owner or component
- Remediation options with risk notes
- Exact retest path
Steps
- Reproduce the failure with the smallest useful condition matrix.
- Record page state, failed requests, console output, events, and timing.
- Compare failing and passing conditions.
- Check focus, disabled states, validation, and accessibility as well as JavaScript errors.
- Trace the failing step to a theme, app, service, configuration, or provider.
- Apply one approved fix.
- Rerun the same journey and monitoring check.
Checks
- Browser and device behavior
- Console and network failures
- Button, form, focus, and validation state
- Cart and checkout transitions
- Performance at the failing step
- Accessibility blockers
- Related traces and application errors
Limits
A timing correlation is not a root cause until the failing path supports it.
