Mastering Decision Matrices

Mastering Decision Matrices in Excel: Step-by-Step Walk-Through and Weighted Scoring Template Provided

Making decisions can often be overwhelming, especially when faced with multiple options or competing priorities. That’s where a decision matrix comes in handy. A decision matrix helps you evaluate and compare different choices based on specific criteria, allowing you to make more informed decisions. In this post, we will walk you through the process of creating a decision matrix using Excel and provide a weighted scoring template to simplify your next big decision. Once mastered you’ll use this time and time again for many options and decisions.

What is a Decision Matrix?

A decision matrix is a structured tool that allows you to organise and assess various options based on a set of predefined criteria. It quantifies subjective assessments, helping clarify which option tends to come out on top based on the criteria most important to you. By applying a weighted scoring system, you can ensure that more critical criteria (the ones you value more) bear more significance in your final evaluation.

Step-by-Step Walk-Through: Creating a Decision Matrix in Excel

Step 1: Define Your Options and Criteria

Begin by identifying the options you wish to evaluate. For instance, if you are choosing a new laptop, your options may include Option A, Option B, and Option C. Next, outline the criteria that are essential for your decision. Common criteria for laptop selection could be performance, battery life, price, and brand reputation.

Step 2: Set Up Your Excel Spreadsheet

Open Excel and create a new spreadsheet. Here’s how to set it up:

1. In Cell A1, type “Criteria”.
2. In Cells A2, A3, A4, A5, list your selected criteria (e.g., Performance, Battery Life, Price, Brand Reputation).
3. In Cell B1, type “Weight”. Under this heading (in Cells B2 to B5), assign weights to each criterion based on its importance (e.g., 0.4, 0.3, 0.2, 0.1). The weights should total 1.
4. In Cell C1, type “Option A”; in Cell D1, type “Option B”; in Cell E1, type “Option C”. 

Your spreadsheet should now look like this:

Step 3: Rate Each Option

In the respective cells under each option (C2 to E5), input scores based on how well each option meets the criteria, typically on a scale of 1 to 10 (1 being poor and 10 being excellent). 

Step 4: Calculate Weighted Scores

Now it’s time to calculate the weighted scores for each option. In the C6 cell, use the formula: 

=SUMPRODUCT($B$2:$B$5, C2:C5)

This formula multiplies the weights by the ratings for Option A and sums the results. Repeat this for Option B and Option C in D6 and E6 respectively.

Step 5: Analyse Results

Once you’ve calculated the total scores, the option with the highest score is generally considered the best choice. This quantitative approach offers clarity amid uncertainty.
