Which step is described as 'implement & evaluate the solution chosen' in the rational decision-making model?

• A. Implement & Evaluate the solution chosen
• B. Identify the problem
• C. Evaluate alternatives
• D. Think up alternative solutions

Answer: (A)

In the rational decision-making model, the phase of implementing and evaluating the solution chosen comes after you’ve identified the problem, generated alternatives, and selected the best option. Implementation is about putting the plan into action—mobilizing resources, assigning responsibilities, setting timelines, and executing the chosen course. Evaluation then checks how well the results align with the objectives and predefined criteria, collecting data, comparing actual outcomes to expected ones, and determining whether the problem is resolved or if adjustments are needed. This step closes the loop by testing the decision in real conditions and providing feedback that can lead to refining the solution or revisiting earlier steps if necessary.
