Key Points

• Herbert Simon made key contributions to enhance our understanding of the decision-making process.
• In fact, he pioneered the field of decision support systems.
• According to (Simon 1960) and his later work with (Newell 1972), decision-making is a process with distinct stages. 
• He suggested for the first time the decision-making model of human beings. 
• His model of decision-making has three stages:
  • ​Intelligence which deals with the problem identification and the data collection on the problem.
  • Design which deals with the generation of alternative solutions to the problem at hand.
  • Choice which is selecting the ‘best’ solution from amongst the alternative solutions using some criterion. 
• ​The figure given below depicts Simon’s decision-making model clearly:

Based on the above points, we can conclude that 'Reaction' step does not find place in Simon's Decision Making Model.​
