Cognitive Control Based Techniques

Erik Hollnagel has developed this line of thought in his work on the Contextual Control Model (COCOM) (Hollnagel, 1993) and the Cognitive Reliability and Error Analysis Method (CREAM) (Hollnagel, 1998). COCOM models human performance as a set of control modes—strategic (based on long-term planning), tactical (based on procedures), opportunistic (based on present context), and scrambled (random) -- and proposes a model of how transitions between these control modes occur
