Today, we're going to start with how to write a usability test plan. What do you think a usability test plan should include?
Maybe the objectives we want to achieve?
Exactly! Objectives should be specific and measurable. For example, we might want to assess if users can log in within three tries. What else?
We need to know who our target users are, right?
Absolutely! Defining users helps tailor the test to their needs. Can anyone give me an example of the target demographic for our project?
Grade 8 students, since we're focusing on their app!
Great! Now let's summarize: a test plan includes objectives, target users, tasks, and metrics. Remember the acronym POTM: Purpose, Objective, Target Users, and Metrics; it will help you remember!

Now, let's dive into how to conduct think-aloud sessions. Why do you think it's important for users to verbalize their thoughts while using a prototype?
So we can understand their confusion and feelings better?
Right! Capturing their real-time reactions gives us deep insights. Can anyone suggest how we might prompt users if they go silent?
We could ask them what theyโre thinking!
Absolutely! Keeping the session neutral is key. Remember, you're testing the prototype, not the person. Let's go over the best practices for moderating these sessions.
Analyzing Findings

After our testing sessions, the next step is analyzing the feedback collected. What do you think we should look for?
We should categorize the issues based on how severe they are.
Exactly! We can classify issues as critical, major, or minor. How would we decide which to address first?
By looking at how often each issue occurs and how badly it affects the user!
Correct! The high-frequency and high-impact issues should take priority in our designs. Letโs explore how we can document these findings.
Building Digital Prototypes

Now that we have our analyzed data, the next step is building a digital prototype. Who can tell me why it's essential to create a prototype?
So we can test our changes and see if they really work!
Exactly! Prototyping enables us to implement improvements virtually. What types of metrics should we track during our tests?
We should measure success rates and gather satisfaction ratings!
Great insights! These metrics will help us compare results and assess whether our changes made a difference.
Reflective Prompts

Finally, letโs reflect on what weโve learned from our testing experiences. What was the most surprising assumption you discovered?
I thought users would find the highlight tool easy to use, but they struggled initially!
Interesting! Reflecting on user problem-solving helps us ground our designs in real needs. What do you think about the combination of quantitative and qualitative data?
The numbers show us success rates, but the comments reveal emotions and deeper understanding.
Precisely! Both data types are essential for guiding future design decisions. Letโs summarize how reflection helps shape our iterative processes.

- Write a usability test plan for one of your prototypes (objectives, participants, tasks, metrics).
- Conduct 5 think-aloud sessions, observing and recording.
- Analyze findings, categorize issues, and prioritize 3 top problems.
- Sketch improvements, noting which user feedback they address.
- Build a digital prototype and test with at least 6 participants.
- Compare results: Show improvement in success rates, time, satisfaction.
- Document changes: What changed, why, and what next.
Detailed Explanation
This chunk outlines a sequence of activities designed to guide you through user testing and evaluation of a prototype. Each point represents a step in the process:
1. Usability Test Plan: Start by drafting a usability test plan for your prototype. This plan should clearly define your testing objectives, the participants you'll involve, the tasks you want them to perform, and the metrics you'll use to evaluate success.
2. Conduct Sessions: Next, conduct five think-aloud sessions where participants will verbalize their thoughts as they interact with your design. Observing them in real-time helps gather valuable insights regarding their experiences.
3. Analyze Findings: After testing, analyze the data you've collected. Categorize the usability issues that emerged and prioritize the top three problems to focus on.
4. Sketch Improvements: As you identify problems, sketch out potential improvements. Be sure to note how each suggestion responds to user feedback.
5. Build and Test: With your improvements in mind, build a new digital prototype. Test this version with at least six participants to gather more feedback.
6. Compare Results: After testing the new prototype, compare the results to identify improvements in success rates, the time taken to complete tasks, and overall participant satisfaction.
7. Document Changes: Finally, document all changes made in response to testing. Explain what was changed, why it was necessary, and what the next steps will be.
Examples & Analogies
Imagine youโre preparing for a school science fair. You start by planning your experiment (your usability test plan) and writing down each step you will take. Then, you conduct the experiment (think-aloud sessions) and observe how things go. After you collect some data, you analyze what worked and what didnโt (analyze findings) and come up with ways to improve your project (sketch improvements). You then rebuild your project with the improvements and test it again with your friends or family (build and test), collecting their feedback to see if they notice any positive changes (compare results). Finally, you write a report explaining everything you did, why you made changes, and how you plan to present it on the day of the fair (document changes).

- In your first test, which assumption was most surprising?
- How did real usersโ problem-solving differ from your expectations?
- Describe how quantitative data (times, error rates) and qualitative feedback (comments) guided your design decisions.
- Why is it important to test low-, mid-, and high-fidelity prototypes through the cycle?
- How can documenting your iterations support future designers and stakeholders?
Detailed Explanation
Reflective prompts are questions designed to encourage critical thinking about the testing process. Each question targets a specific aspect:
1. Surprising Assumptions: Reflecting on which assumptions proved false or unexpected during your first test can help you understand biases or gaps in your initial planning.
2. User Problem-Solving: Observing how actual users approach problems can differ vastly from your design expectations. This insight can be crucial for future designs.
3. Role of Data: Both quantitative (measurable) data and qualitative (descriptive) feedback are valuable. Understanding how these informed your decisions helps you improve your design process.
4. Prototype Fidelity Importance: Testing low-, mid-, and high-fidelity prototypes is essential because it ensures that you gather feedback at various stages, from basic concepts to almost final designs.
5. Support Through Documentation: Documenting your iterations not only helps you track changes for your own reference but also serves as a useful resource for future designers and stakeholders who may work on similar projects later.
Examples & Analogies
Think of these reflective prompts like a post-game analysis after a sports match. After the game (testing), players and coaches might discuss what strategies worked and which didnโt (surprising assumptions), how the team adapted during the game (usersโ problem-solving), and how statistics like possession time and player performance shaped their training strategies (data guiding decisions). They also consider why itโs important to practice plays at different intensities and scenarios (prototype fidelity), and they might review game footage to inform their practice for the next match (documentation).
