Critiquing is a form of decision support whereby a computer system monitors the actions of people to help prevent errors. Critiquing systems developed to date (spell checkers, problem-solving assistants, etc.) traditionally support a single person performing a static, non time-critical task. We have now developed a critiquing system in the more dynamic world of process control. Specifically, we support the execution of complex procedures in petrochemical plants with an on-line, executable dynamic procedures decision support system, where we introduce critiquing as a means to assist teams of operators as they execute procedures in real time.
