"Successful execution of any plan requires resources. Plan activities indicate resources which must be allocated in preparation for implementation of the activity which uses the resources. The achievement of plan activities requires allocation of human, asset, consumable and service resources." - HL7 Care Plan Domain Analysis Model. Note that the HL7 DAM has three subtypes of Resource Allocation: Asset Allocation, Consumable Allocation, and Service Allocation, whereas the FHIM currently combines these. We may wish to split these subtypes out in the future.
