W6_S.Algheilani_ using Decision Matrix Analysis in Decision Making

1. Problem Recognition

I decided to buy a new 4×4 car for my outdoors activities. There are many options in the market to choose from. Each one of them been promoted by a special features that will make off-roading a pleasant and reliable experience. The car is supposed to be driven into a sandy and rocky road.

1. Development the Feasible Alternative

The following are the final refined list that the car will be chosen from:

• Jeep wrangler sport with two doors.
• Toyota Tundra
• Ford F-150
• Dodge Ram 1500
1. Development of the Outcome for Alternative

The following criteria to be considered while selecting the car which matches needs and expectation:

• Exterior & Interior design: To bring all weather capability that testifies to its off-road power.
• Performance: the performance must comply with the hard and difficult weather conditions in Oman.
• Cost: The cost should be reasonable in order for me to consider the car.
• Popularity: Popularity usually reflects the durability and the reliability of the car and also might reflect the after sale service that is provided by the dealer is satisfactory.
• Resale Value: Resale Value is another important element in deciding the car to be purchase. Cars can vary considerable in term of resale price.
1. Selection of Criteria

In this blog, am going to use an analytic matrix that will help in making the decisions and comparing the different aspects of comparison such as cost, performance and Resale value. One of the most popular and easy to apply method to apply is Decision Matrix Analysis. Decision Matrix Analysis is a useful technique to use for making a decision. It’s particularly powerful where you have a number of good alternatives to choose from, and many different factors to take into account. This makes it a great technique to use in almost any important decision where there isn’t a clear and obvious preferred option.

Being able to use Decision Matrix Analysis means that you can take decisions confidently and rationally, at a time when other people might be struggling to make a decision [1].

1. Analysis and Comparison of the Alternative

These are the steps in order to use the decisions using the Decision Matrix:

• Step 1: List options as rows
• Step 2: Determine important attributes and add/remove columns, as appropriate
• Step 3: Assign relative weights to each attribute in row 9 (i.e. an 8 would be twice as important as a 4)
• Step 4: Assign objective 0-100 scores for how option satisfies each attribute (best to do this on an attribute-by-attribute basis)
• Step 5: Options with the highest scores should be considered

For each attribute, assign a relative weight that is greater than zero. In this decision matrix, the range of numbers doesn’t matter; it’s the relationship between those numbers that matters. For example, if Cost is assigned a weight of 8 and Performance is assigned a 4, you’re saying that Cost is twice as important as performance in your decision. Naturally, lower weights are less important than higher weights, and it’s okay if multiple attributes share the same weight. In that case, you’re saying that those attributes will be treated equally. In group situations, the discussion about the relative importance of these attributes can be very enlightening, and it’s a fantastic way to build consensus.

Applying these steps and using the inputs from the dealers and costumers the following table illustrate the comparison between the 5 options:

Table1. Decisions Matrix Analysis [2]

1. Selection of the Preferred Alternative

From Table.1 it is clear that the Jeep Wrangler is scoring the highest score with 88% and 8% more than the closet competitors. This might easily explain by the popularity of the car in Oman. Where the costumers preferred the car based on its inexpensive price which is affordable by most of the young drivers who are looking for an affordable car which will fulfil their adventurous activities throughout the country.

1. Performance and Evaluation of Result

This might easily explain by the popularity of the car in Oman. Where the costumers preferred the car based on its inexpensive price which is affordable by most of the young drivers who are looking for an affordable car which will fulfil their adventurous activities throughout the country.
