Today, we're diving into how to create meaningful recommendations from user testing insights. Can anyone explain why recommendations are essential?
I think recommendations help improve the design based on user needs.
Exactly! Recommendations bridge the gap between what users experience and how we can enhance their experience. What's a key component of a sound recommendation?
A problem statement that clearly defines the issue.
Right on! A problem statement sets the foundation for understanding the challenges users face.
Gathering Supporting Evidence

Let's talk about supporting evidenceβhow do we gather data to support our recommendations?
We can use metrics collected from usability tests.
That's correct! By analyzing metrics like average completion time or error rates, we provide a factual basis for our recommendations.
Can this evidence also include qualitative feedback?
Absolutely! Combining quantitative and qualitative data gives a fuller picture of user experiences.
Proposing Changes

What do we do after we gather our supporting evidence?
We suggest changes based on the evidence.
Yes! It's vital to propose realistic and specific changes that can be tested. What's a good example of this?
If users hesitate with an icon, we might suggest replacing it with a clearly labeled button.
Great example! It shows we are directly addressing user issues.
Expected Outcomes

Now, let's discuss the expected outcomes of our recommendations. Why is this an important step?
It helps gauge how effective the changes will be.
Exactly! By anticipating outcomes, we can prioritize which changes to implement based on expected benefits. Can anyone suggest an expected outcome for our earlier button example?
Maybe reducing the decision time by 20%?
Right! Estimating improvements like that helps us make informed design decisions.
Introduction & Overview

Quick Overview
Standard
In this section, the focus is on formulating evidence-based recommendations from usability testing data. Key steps include defining problem statements, supporting evidence, proposed changes, and expected outcomes, all aimed at improving design effectiveness and user satisfaction.
Detailed
Formulating Evidence-Based Recommendations
This section is pivotal in converting insights from usability tests into structured, actionable recommendations that enhance user experience with the design. It outlines a systematic approach for identifying issues, framing supporting evidence, proposing actionable changes, and predicting their impact.
Key Components:
- Problem Statement: Clearly articulate the recurring issues identified during usability testing. For instance, stating that users misinterpret a certain icon can clarify the root of user confusion.
- Supporting Evidence: Base your recommendations on solid data sourced from user interactions, such as average decision times or error rates encountered when using features. This lends credibility to your proposals.
- Proposed Changes: Suggest implementable revisions, such as redesigning an icon for clarity, while also considering testing alternatives for placement and design, which ensures flexibility in resolving usability challenges.
- Expected Outcome: Facilitate a predictive understanding of the effects of proposed changes. Estimating potential improvements in efficiency or user satisfaction can help prioritize changes based on impact.
This systematic approach ensures that feedback from real users is directly translated into design enhancements, solidifying the efficacy of each iterative leap in the design cycle.

Creating Problem Statements
Chapter 1 of 5

Chapter Content
- Problem Statement: βUsers consistently misinterpret the βhamburgerβ icon as menu access, leading to task delays.β
Detailed Explanation
A problem statement succinctly identifies an issue encountered by users, providing a clear focus for enhancements. In this example, the problem is that users are confused by the icon representing the menu. Highlighting the specific issue helps teams understand what needs fixing to improve user performance.
Examples & Analogies
Think of it as explaining a traffic jam on a highway. If the road signs are confusing, drivers might take the wrong exit, leading to delays. Identifying that confusing signage is the problem helps engineers focus on ways to improve that signage and streamline traffic flow.
Supporting Evidence

Chapter Content
- Supporting Evidence: βSeven out of ten participants paused for an average of 8 seconds before clicking the icon.β
Detailed Explanation
Supporting evidence provides quantifiable data to back up the problem statement. By collecting data from usability testing, you can illustrate the extent of the issue, making it more persuasive. Here, the metrics reveal that a significant number of users faced delays, reinforcing the need for change.
Examples & Analogies
Imagine a teacher grading a student's essay. If many students frequently pause to think about the meaning of a term used in the essay, the teacher knows to explain that term more clearly in future lessons. This evidence shows the problem isn't just isolated but is experienced by many.
Proposed Changes

Chapter Content
- Proposed Change: βReplace the icon with a labeled βMenuβ button and test alternative placements.β
Detailed Explanation
This chunk outlines a specific actionable resolution to the identified problem. It suggests changing the confusing icon to a more intuitive label, which users can quickly recognize and understand. Testing alternative placements ensures that the solution is effective in various contexts.
Examples & Analogies
Consider how a coach might adjust a team's play strategy after observing confusing performance. If players frequently misinterpret signals, the coach might decide to use clear signals insteadβthis change provides clarity, just like labeling the icon improves user experience.

- Expected Outcome: βAnticipate a reduction in decision time by at least 20%, improving overall task efficiency.β
Detailed Explanation
Expected outcomes project the potential impact of implementing the proposed changes. By estimating measurable improvements (such as a 20% reduction in decision time), the recommendation becomes more actionable and motivates stakeholders to support the change because they can see potential benefits.
Examples & Analogies
Think about switching from a slow internet service provider to a faster one. If the new provider guarantees improved speeds, you can expect to complete online tasks much quicker. Similarly, estimating outcomes helps stakeholders visualize the benefits of a change in design.
Impact-Effort Matrix

Chapter Content
Employ an impact-effort matrix to rate each recommendation: plot high-impact, low-effort items as top priority.
Detailed Explanation
An impact-effort matrix helps prioritize recommendations based on their potential benefits versus the amount of work needed to implement them. By identifying high-impact, low-effort changes, teams can make effective improvements quickly, maximizing resource use and increasing project efficiency.
Examples & Analogies
Itβs like organizing a chore list. If you can clean your small bathroom in 15 minutes, but vacuuming the big living room takes an hour, cleaning the bathroom may be a higher priority due to the low effort and significant impact on tidiness.
Key Concepts
-
Evidence-Based Recommendations: Proposals derived from user testing data.
-
Problem Statement: A clear definition of the user issues encountered.
-
Supporting Evidence: Data that supports the rationale for design changes.
-
Expected Outcome: Predicted effects of the proposed modifications.
Examples & Applications
A common problem statement might be 'Users take too long to find the payment options,' leading to a recommendation to simplify navigation.
Supporting evidence could show '80% of users reported confusion with the current design,' backing the recommendation to redesign specific elements.
