Systems, methods, and other embodiments associated with controlling a display screen with graphical objects in a computing system are described. In one embodiment, a method includes receiving a service request, identifying attributes of the service request, and using the attributes to retrieve from a probability data structure data records. Service criteria for processing the service request are identified, and a probability that the service request will transition to a target state in compliance with the service criteria is calculated based upon the retrieved probabilities. A display screen is controlled based upon a prediction of whether that the service request will transition to a target state in compliance with the service criteria.
