Rational Decision Making Process Assignment Abroad


The Rational Decision Making Model is a model which emerges from Organizational Behavior. The process is one that is logical and follows the orderly path from problem identification through solution. It provides a structured and sequenced approach to decision making. Using such an approach can help to ensure discipline and consistency is built into your decision making process.

The Six-Step Rational Decision-Making Model

            Define the problem.

            Identify decision criteria

            Weight the criteria

            Generate alternatives

            Rate each alternative on each criterion

            Compute the optimal decision

1) Defining the problem

This is the initial step of the rational decision making process. First the problem is identied and then defined to get a clear view of the situation.

2) Identify decision criteria

Once a decision maker has defined the problem, he or she needs to identify the decision criteria that will be important in solving the problem. In this step, the decision maker is determining what’s relevant in making the decision.

This step brings the decision maker’s interests, values, and personal preferences into the process.

Identifying criteria is important because what one person thinks is relevant, another may not. Also keep in mind that any factors not identified in this step are considered as irrelevant to the decision maker.

3) Weight the criteria

The decision-maker weights the previously identified criteria in order to give them correct priority

in the decision.

4) Generate alternatives

The decision maker generates possible alternatives that could succeed in resolving the problem. No attempt is made in this step to appraise these alternatives, only to list them.

5) Rate each alternative on each criterion

The decision maker must critically analyze and evaluate each one. The strengths and weakness of each alternative become evident as they compared with the criteria and weights established in second and third steps.

6) Compute the optimal decision

Evaluating each alternative against the weighted criteria and selecting the alternative with the highest total score.


All managers face issues every day that need decisions; decisions about managing employees, resources and setting plans and strategies. And to do that, there are two ways to make a decision, Intuitive way and rational decision making way.

In last article (Effective decision making) we’ve discussed how to make Effective decisions, and in this article, we’ll discuss how to make rational decisions.

Rational decision making model definition:

Rational decision making is a multi-step and linear process, designed for problem-solving start from problem identification through solution, for making logically sound decisions.

The rational decision making model is a good model to make good decisions because it depends on rational way used for problems solving.

Rational decision making model steps:

If you want to make a good decision which helps you to achieve your goals; you should depend on the available facts to make a careful analysis to make a decision as we’ll explain in the following steps:

Step 1: Identify and define the problem:

The first step to make a rational decision is to identify and describe the problem by defining the current and desired states and defining the alternatives:

  • Keep in mind during identifying the problem to identify the cause of the problem, not the symptoms.
  • Define the gap between the current state and the desired state. And the gap must be enough to motivate the involved people to implement the decision.
  • Define all available options and don’t think about quick solutions.

Example: if your family is growing and you have a small house which doesn’t meet your needs. Let’s assume that your decision is buying a bigger house to overcome that issue.

Note that: buying a new house is a solution (not identifying the problem), and by this way you don’t think about the cause of the problem (space), the gap between the current and desired state and all alternative options.

The cause of the problem:

Buying a new house isn’t a problem, it’s a symptom. And the cause of the problem is the (Space).

The gap between the current and desired state:

In our example, you should mention the available space and the needed space.

All alternative options

Think about all alternatives:

  • If there is unneeded stuff in your house can be removed to free up space.
  • Having a space to build a new room in the house.
  • Buying a new house.

Step 2: Identify the decision criteria:

The second step in the rational decision making model is outlining all the criteria ahead of time because those criteria will be a good guide to make a decision

Example: let’s get back to our problem, space is our issue and we need to identify some criteria to measure all alternatives and determining if there is solution is better than others, in this example our criteria are (time and cost)

Time: we should think about:

  • When will we need that space?
  • When will solving the problem be critical?
  • And how long will each option take?

Cost: these criteria are important to know if there is some options cost more than others; so you should know:

  • How much will each option cost?
  • How much money do we have?

Note that: if our problem is buying a new house instead of solving a space issue, we would establish criteria a little differently; and we would likely focus on things like distances to activities, crime per capita, quality of schools, and some other factors.

Now we’ve identified the problem and the decision’s criteria, it’s the time to weigh those criteria:

Step3: weight established criteria:

We need to weigh those criteria because each criterion is unlikely to have the same level of importance; there are few ways you can use to accomplish this step:

1- Using an absolute comparison:

You can use this method which you commonly find costumers’ ratings; this comparison is helpful because it allows you to compare items side by side. So if you’re shopping for a product, you can look through customers’ reports and ratings and compare different types of the product in a specific category.

Those reports and ratings are accomplished by incorporating a ranking system where the user enters a value reflecting the importance of the criteria on a scale.

Example: let’s say that there is a scale starting from “1” and going to “10”. “1” indicates that the criteria has no importance to us and a score of “10” indicates that the item is very important. So we would go through each criteria and use this method to weigh their significance to us.

Since we are evaluating the criteria on their own metric and not in relation to another criteria so we can assign the same value to different criteria.

2- Using relative comparison

A relative comparison is made by comparing each criteria with another. So by using relative comparison; we can obtain what criteria are most important to us. This can be helpful when you attempt to weigh criteria that have similar ratings by using an absolute comparison.

So by comparing them against one another we firmly know which one is more important.

Step 4: Generate list of alternatives

Once we have identified a thorough list of criteria and weighed the importance of those criteria, now we can generate a list of alternatives.

During this step, our goal is generating many alternatives as possible. The more alternatives that we generate, the greater the likelihood is that we’ll come up with an effective solution to our problem.

Going back to our problem, we can generate a few alternatives, including buying new house, building another room, placing possessions in storage, or even placing a few kids up for adoption.

Keep in mind, in this stage we define all possible options, no matter they are good or bad solutions because we’ll think about that in the next stage.

Step 5: Evaluate the alternatives:

At this stage, we want to evaluate the alternatives that we’ve identified using the criteria that we’ve identified in step2. This step may be lengthy depending on the number of criteria and the number of alternatives.

Let’s go back to our Example: we’ll use a simple rank-order method to rank the alternatives in the criteria that we’ve identified. We’re also establishing weights to each criteria based on our findings from step 3. as shown in the following table:

 Long term-solution (0.6)Time (0.3)Cost (0.1)
Buying a new house144
placing possessions in storage411
Increase size of home232
Reduce family size323

Step 6: Determining the optimal decision

The sixth step in our rational decision making model is determining the optimal decision. In order to know the optimal decision, we’re going to multiply ranking for each alternative by that criteria’s respective weight.

 Long term-solution (0.6)Time (0.3)Cost (0.1)Total
Buying a new house1*0.6 = 0.64*0.3 = 1.24*0.1 = 0.40.6+1.2+0.4=2.2
placing possessions in storage4*0.6 = 2.41*0.3 = 0.31*0.1 = 0.12.8
Increase size of home2*0.6 = 1.23*0.3 = 0.92*0.1 = 0.22.5

Since each criteria has a different level of importance, we use these levels to assign more influence to the results in categories that have more importance.

And since we’ve already weighed the established criteria in step 3, we know exactly which criteria to give more importance to as we determine the optimal decision. As you can see, buying a new house appears to be the best solution based upon the evaluation.

As we end I want to leave you with a word of caution. Models, by the very nature, are clear, organized, and logical. Everything in the real world is not. So applying a model to an environment isn’t perfect but it’s a difficult task.

It is true that statistically, that who uses such a model will make more rational decisions, whether in his business or in personal lives. But money, time, and other constraints can affect a manager’s ability to use such a model as it was intended; because maybe you can’t evaluate every alternative and identify every possible option. But if your goal as a manager is to make more rational decisions, this is certainly a start.
