Problem: Analyse how decision-making is applied at each stage of the problem solving process. Range: Analyse is to provide an in-depth examination of how decision-making is applied at each stage of the 6-stage problem solving process. How decision making is applied at each stage refers to the 6-stage problem solving process of the 6-stage model approach: 1) understand the situation, 2) identify problems, 3) identify potential solutions, 4) establish decision criteria, 5) select solution, 6) implement solution.
