Today, we will learn about the Filled Decision Matrix. It's a fantastic tool for evaluating different design concepts. Can anyone tell me why decision matrices can be useful?
Because they help organize our thoughts and compare options!
Exactly! They help us systematically weigh our options. Now, each criterion in our matrix has a weight. Can someone explain what that means?
It means we prioritize some criteria over others, right?
Yes! This way, we can focus on the most critical aspects of our design. Remember, the sum of weights should always equal 1. This helps balance priorities. Let's look at a filled example next!
Now let's dig deeper into criteria. Why do you think accessibility is so crucial in design?
Because we want our designs to be usable by everyone, including those with disabilities!
Correct! And we assign weights to emphasize accessibility, which in our case could be 0.25. This means it's one of our top priorities. How about performance – why might that matter?
If a design is slow, people won't use it, right? So it should also have a high weight!
Exactly! Each weight reflects how we feel about the relative importance of that criterion.
Let’s go through how we calculate the total scores for each concept using weighted scores. If Concept A has scores of 8, 6, and 9 for accessibility, performance, and user delight respectively, how do we calculate the total?
We multiply each score by its weight! For accessibility, it’s 8 times 0.25!
Correct! So, what does Concept A’s accessibility score become?
That would be 2.0.
Right! And we repeat this for each score to get the total for Concept A. This systematic approach really helps clarify our decisions.
Now, after calculating the scores, how do we decide which concept to go with?
We select the one with the highest total score, right?
Exactly! What if two concepts have very close scores?
Maybe we need to consider qualitative factors or do a sensitivity analysis to see how changes in weights affect outcomes?
Fantastic idea! Sensitivity analysis helps us understand the robustness of our decisions.
Can anyone think of a practical scenario where we could apply the Filled Decision Matrix?
Maybe when choosing features for an app?
Great example! Funding decisions in product development also apply this method. How about marketing choices?
Selecting which ads to run based on target audiences and costs!
Exactly! The matrix is flexible for various decision-making scenarios.
Represents the relative importance of each evaluation aspect.
The sum of all weighted scores, indicating the best-performing concepts.
A visual representation used to compare multiple alternatives against defined criteria.
A method to test how changes affect outcomes in decision making.
An example of a Filled Decision Matrix may involve three concepts evaluated based on accessibility, performance, and user delight, helping teams select the best option.
In a project to develop a new app, the team can use the Filled Decision Matrix to decide which features to prioritize based on weights assigned to key metrics.
In a matrix so fine, we weigh and combine, choices lined just right, making decisions bright!
Once there was a team trying to select the best app feature. They gathered around a matrix, weighing criteria like performance and delight until, at last, they uncovered the best choice!

A score obtained by multiplying the performance score of a criterion by its assigned weight.
Standards or benchmarks used to evaluate the alternatives in the decision matrix.
A technique used to determine how different values of an independent variable affect a particular dependent variable under a given set of assumptions.
The measure of how easily all users, including those with disabilities, can use a design or product.
The effectiveness of a design as determined by metrics such as speed and responsiveness.
The level of satisfaction and enjoyment that a user experiences when interacting with a design.
The Filled Decision Matrix uses a structured approach to prioritize design concepts based on weighted criteria.
This section describes the Filled Decision Matrix, a tool for systematically evaluating multiple design concepts against criteria like accessibility, performance, and user delight. By assigning weights and scores, this method helps select the most viable concept.
The Filled Decision Matrix is a strategic decision-making tool that enables designers to evaluate different concepts systematically. The method involves defining criteria that the concepts must meet, such as accessibility, performance, cost, user delight, and technical risk. Each criterion is assigned a weight according to its importance (ranging from 0 to 1), ensuring that decision-makers focus on what matters most.
By providing scores for each concept corresponding to each criterion, stakeholders can calculate a weighted score for each design. This score is obtained by multiplying the score from each criterion by the corresponding weight assigned to that criterion.
For example, if a concept scores 8 in Accessibility (weight of 0.25), it contributes 2.0 to the overall score (8 * 0.25). The decision matrix illustrates this process clearly, revealing which concepts best meet the desired criteria and facilitating informed decision-making.
The significance of using the Filled Decision Matrix lies in its systematic approach, reducing the likelihood of biases influencing decision-making while providing a clear, visual representation of the evaluation process.
