Test and Scale — in practice

Test definitions and products before embedding — a new data model may not answer the same service question.

Definition migration

  • Case → action shift
  • Side-by-side reconcile
  • Anchor patient vignette

MHSDS-like + local pack

  • Same fact, two products
  • Test inclusion rules
  • Compare before publish

Ideas under test

  • Small tests logged
  • Evidence before scale
  • Park or promote

Epic / ADF:

  • Workflow capture may change what events exist
  • ADF refresh on schedule ≠ correct meaning
  • Test mappings, inclusion rules, validation before sign-off

A new data model may not answer the same service question — even when the pipeline is green.
