In any automated business process there is a need to interact with human agents to make decisions, supply additional data or to perform tasks in the real world such as telephoning a client. In Cúram workflow, such steps in a process are modeled using manual activities. A manual activity specifies where in the business process human intervention is required. It also specifies the information the user will get when notified that they must perform a task and also the selection of the agents to which the work will be assigned.
