Data quality

Publication Standards

What a vehicle record needs before its maintenance schedule is published.

Requirements before publication

  • Vehicle identity confirmed - make, model and year
  • Correct model year applicability
  • Correct powertrain applicability
  • A source document attached to the record
  • Maintenance rules linked to that source, not entered freehand
  • Special driving conditions preserved as their own rules where the source defines them
  • Conditional equipment handled rather than assumed
  • Ambiguous data held for review rather than guessed
  • Validation checks passed
  • Status marked approved and then published

A vehicle that has not met these requirements remains unavailable on the site. An incomplete or unreviewed schedule is not published in a partial or estimated form.
