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.
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
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
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
