Today I was very confused by two different terms with almost the same meanings. Process or model? Lots of authors replace “decision making model” term with the “decision making process”. I can assume that they have something in common, for example the decision making cycle. Starting both with determine the requirements for the decision (time, amount of support, its importance), they then switch on the participants (all members provide the input or request more information). Later the alternatives have to be defined with their pros and cons. Check if the group come to some agreement or not. Identify the criteria for making decision and then choose the methodology with its tools that can be applied. Finally, by gathering and analyzing information group will come to a certain decision.
To my mind, these two terms have lots of other similarities. However, “the model” involves the approach which sometimes changes the whole “process of decision making”. The approach can be also known as a “philosophy” it can sets the clock and define how group will come to a certain decision. Thus, I think, model involves the process, and its term is more broader then “the process” term.
