Issue Priorities

Issues found via OATMEAL tests are given a Priority Level from P1 (most severe) to P4 (least severe).

  • P1 and P2 issues must be fixed before the next release.
  • Issues found in automated tests and some failures to implement the eBay MIND Patterns don't always follow these prioritizations.

P1 Issues

A barrier that makes completion of a task impossible for some users.

P1 Examples

  • Interactive element not in tab order
  • Pinch-to-zoom disabled
  • Accessible name not provided (e.g. unlabelled form inputs, images missing alt text)

P2 Issues

A barrier that makes completion of a task difficult for some users.

P2 Examples

  • Color contrast below the contrast minimum
    • Workaround: User can provide a custom stylesheet
  • Focus indicator missing on element, but present on adjacent elements
    • Workaround: User can determine focus by navigating through surrounding elements
  • Keyboard focus does not go where the user expects
    • User has to discover how to get focus where they expect it to be

P3 Issues

A barrier that makes completion of a task tedious or annoying for some users.

P3 Examples

  • Widget interaction different from the established pattern
    • Annoying: User has to learn multiple of the same type of widget and then figure out which they're using each time
  • Page missing "Skip to Main"
    • Tedious and Annoying: User has to navigate through all repeated header elements on every page
  • Redundant labeling on a button, link, or input
    • Tedious: User has to listen through extraneous information

P4 Issues

A non-barrier that technically fails accessibility guidelines.

P4 Examples

  • Non-unique IDs on unreferenced elements
  • Duplicated attributes with the same value
