Mapping methodology

These guidelines were developed to assist map developers to produce a map which benefits all the users of the map and ensures that the downstream users of data produced as a result of a map are able to use the information consistently and reliably.

A robust mapping methodology will assist in producing quality maps that are useable, reproducible and understandable.

Usable

• Quality mappings will support the use cases they were intended for

• There is a maintenance in meaning of source and target code systems

• Mapping needs to be able to be maintained where:

  • there are updates to source code system

  • there are updates to target code system

  • there are updates to user requirements or use cases

Reproducible

• Clear methodology ensures a repeatable quality approach to mapping

• Mappings need to employ authoritative reference sources uniformly

• Documentation defines all assumptions, rules, and procedures required to manage context and create the map

Understandable

• All mappings should have a stated purpose and audience

• Map documentation is complete, clear, and unambiguous

• Mappings define source and target domain scope for the map

• Consider also possible instances where MIS–USE of the map may influence data quality, reporting or interpretation of data /analytics
