A lot of the data stored for a person or prospect persons meets the Cúram definition of evidence. It is used in eligibility and entitlement calculation, and often it is information retrieved from an individual or household as part of an application or intake process. The per-existing Cúram evidence structure is limited as it prevents data deemed to be evidence being maintainable on a case even though it may be used in eligibility and entitlement. This results in a poor usability experience because the user is forced to work outside of a case to maintain data for a person. It also does not provide a full audit trail of changes made over time. Maintained as static data, it is not configurable. If there is a requirement to change an attribute or add further attributes, then this requires a customization effort. Additionally, any data changes at the participant level can cause a reassessment on the case without the user ever being aware of it.
