A claim assignment system can cause insurance claims to be assigned among different groups within an insurance company. The claim assignment system can have a rules engine and a machine learning engine that both recommend a group to which a claim can be assigned. The claim assignment system can be configured to select the group for the claim based on a recommendation from the machine learning model if a confidence level of the machine learning assignment recommendation meets or exceeds a threshold value, and otherwise select the group for the claim based on the assignment recommendation from the rules engine.
