A system for controlling a complex process in which a supervisory sequential controller interface provides automatic sequencing of a plurality of sequential steps of a procedure for operating the complex process, and a display in dynamic communication with the supervisory sequential controller interface and responsive thereto, displays an overview of the status of progression through the sequential steps relative to the entire process. The display provides a global view of the status of the procedure identifying the state of substantially each criterion that needs to be satisfied to advance to the next sequential step and providing verification that substantially each command to be given upon satisfaction of the criterion, has been executed.
