In the field of psychology, he was very successful in science, and in 1949 he received a professor in Harvard at the Faculty of Public Relations.

Decision-making stages

Classically, five phases of the decision-making process are identified:

• Target setting. It's one of the most important steps. In fact, setting a target is the right question to be answered. This stage is very important because if we are to find a solution to the wrong task, the result will be lame.

• Modelling. At this stage, the objectives are set (why do we have to deal with the task?) and an indicative plan of action is being developed, that is, a model of how we will seek a response to the question.

• Validation of the model. The main question to be answered at this stage is whether all the substantive details of the real situation are incorporated into the model?

• Model application. Attempting the task through a model.

• Model renewal. Refining, clarifying the model. It's a very important phase, too.
