Read & Understood is a new feature of ARIS 10 SR 10.

It is a business / GRC type of workflow that allows process owners to ask their workforce to confirm that they have read & understood the information in model. 

It is a way of enforcing process conformance, similar to asking people to sign a contract.

It is a powerful feature to increase the practical value of formal models by making them more relevant.

Here is a short video including demo:
