“Choice of aim is clearly a matter of clarification of values, especially on the choice between possible options.” W. Edwards Deming
Once we have developed a list of alternatives, the next step in the decision making process is to rank them. The ranking process requires basic elements to keep it simple, yet effective. The first element required is developing a criterion list to assess all your possible alternatives against. Listed below, you see an example alternatives list I have created for the laptop example I mentioned yesterday. For this example I singled out what I felt were the most important factors. The same example can be adjusted for just about any decision. Whether you are assessing a new car, business idea, partner, employee or a potential investment opportunity. Develop a list of criterions against which you can assess all the available alternatives. It is important to rank all the alternatives against chosen criterions.
The next element that is required is, assigning weight ages according to your preferences. I used a 10 point scale for this example, however, there are other ranking scales, and I have personally used a 100 point scale as well. This depends entirely on the complexity of the decision, and the number of criterions being used to assess each alternative. The next aspect is to assign specific scores to each option, based on the criterion. I have used a 5 point scale for the assessment in the example below, 5 meaning, very satisfied and vice versa. After you grade each criterion, multiply the scale score with the assigned weight-ages. Finally, add each options total score, and you have a decision based on resulting total scores for each alternative.
A further complexity to the model above, particularly when making business decisions, is to add a risk component. I left this component out of the above example to make it easier to understand. Adding a risk component can help you weigh the risk-reward ratio of each alternative. This has been very helpful to me when assessing different business opportunities. The model described above, brings together all the factors we have spoken about in the last couple of days. It is important to understand the logic behind each of the components, and the manner we arrived at this stage. Once we have a total score, we are ready to move to the last stage of the decision making process.
