Today, we are going to discuss the iterative prototype cycle: Build, Test, and Improve. This cycle allows us to create better designs by repeatedly refining our prototypes. Let's break down each step.
What exactly does 'Build' mean?
Good question! 'Build' means creating your initial prototype. Start simple with materials like paper, and then as you receive feedback, you can add more complexity. Always keep your focus on solving a specific problem.
Can you remind us what types of materials we can use?
Absolutely! You can start with low-fi materials like paper sketches or cardboard, and move to digital tools as you refine your prototype. Remember, the idea is to iterate quickly!
So, we keep upgrading the prototype after the feedback?
Exactly! And that leads us to the next step: Testing. It's where we seek feedback from users. Always ask, 'What works?' and 'What would you change?' Gathering insights is crucial.
What if people have conflicting feedback?
Great point! You will need to analyze the feedback for common patterns. Combine the insights, particularly looking at the 'warm' feedback and the constructive 'cool' critiques to identify what to improve. That takes us to the Improve step.
In summary, remember the iterative cycle: Build, Test, Improve. Each cycle brings us closer to a solution that is mindful of user experience.

Let's dive deeper into the 'Build' phase. What are some initial actions we should take when we start building a prototype?
I think we should start with brainstorming the problem first.
Exactly! Clarifying the problem is crucial. Then, you can make a simple model illustrating your idea.
Should we focus on details right away?
No, not at first! Focus on the core concept, and you can always refine details later. Use rapid materials for easier adjustments.
What if I want to go straight to a digital model?
You can do that, but remember, starting simple allows for easier feedback. Once you have clarity and confidence, moving to digital is great for high fidelity. You can use tools like Tinkercad for 3D elements or app mockup software.
Remember, the key here is iteration. Start simple, test ideas frequently, and iterate!
Step 2: Test

Now let's discuss the 'Test' phase. Why do you think it's important to gather feedback early?
So we can find out what users really think about our prototype?
That's correct! Gathering real feedback helps identify usability issues and areas for enhancement. Always ask friendly questions.
Is observing reactions important?
Yes! Observing both verbal and nonverbal reactions can reveal insights that words alone may not express. Note everything carefully.
What should we do if users are confused?
If users are confused, that's a sign that you may need to revise your prototype to make it clearer. Focus on their experiences and adjust accordingly.
In summary, during the testing phase, engaging users and observing their experiences allows you to gather valuable data we can use to enhance the prototype.
Step 3: Improve

Finally, let's talk about the 'Improve' phase of the cycle. What is the first thing you should do after collecting feedback?
We should look for patterns in the feedback?
Exactly! Analyzing feedback for common themes is crucial. You should combine positive feedback with constructive critiques to formulate a path forward.
How do we know what changes to make then?
You’ll want to focus on any structural issues raised, as well as visual or functional enhancements that need attention. Aim for clarity and improved user experience.
And once we make improvements, we start the cycle again?
Yes, exactly! This is an iterative cycle. Each round makes your prototype better, so always prepare for the next build and test phase. It’s continuous advancement!
To summarize, in this last phase, we focus on refining based on user insights, which leads us back to the next round of building and testing. This cycle ultimately hones our design.

Now, let’s visualize how we can implement this iterative cycle over a timeline in the classroom. Our project will develop over five days. What do you think we might do on Day 1?
Start with a paper sketch and role-play our ideas?
Exactly! Day 1 focuses on conceptualizing. Then, on Day 2, we collect feedback and improve that initial paper prototype, right?
Then we could make a digital or foam model for Day 3?
Yes! Followed by further testing. Day 4 is for developing a high-fidelity model, and finally, we'll reflect on our journey and improvements on Day 5.
After all of that, we can present our final designs!
Absolutely! Each step is crucial in learning how to iterate effectively through real feedback experiences. This is how we evolve our designs into something that truly works for users.
To conclude, remember that each prototype cycle builds on the previous one and helps refine designs until they meet user needs effectively.

Iterative Prototype Cycle: Build → Test → Improve
Prototyping is not a one-time event; rather, it is an ongoing, iterative process that involves three crucial steps: build, test, and improve. Each iteration strengthens the design, making it clearer and more user-friendly.
Step 1: Build
- Start with a simple prototype and gradually add complexity across iterations.
- It's essential to clarify the specific problem that the prototype aims to address.
- Utilize rapid materials for initial prototypes, beginning with paper and upgrading to more sophisticated options such as digital formats or plastics.
Step 2: Test
- Gather feedback from various stakeholders including classmates, teachers, and potential users.
- Use constructive and friendly questioning to identify what works, what is confusing, and what could be improved.
- Observing both verbal and nonverbal reactions can provide insights into user experience.
Step 3: Improve
- Analyze the feedback to identify patterns and combine positive reactions with areas for improvement.
- Make adjustments to the design based on feedback, which may involve structural changes, visual tweaks, or functional enhancements.
- Prepare for the next cycle of build and test, reinforcing the continuity of this iterative process.
Classroom Cycle Example
An effective application of this iterative cycle in the classroom can be mapped out across several days, including:
1. Creating a paper sketch and role-play on Day 1.
2. Collecting feedback and improving the prototyping on Day 2.
3. Developing a digital or foam prototype on Day 3 with additional testing.
4. Finalizing a high-fidelity prototype by Day 4, followed by reflection on the improvements made on Day 5.
Through this structured process, students learn to iterate thoughtfully based on real user experiences, ultimately leading to innovative and user-centered design solutions.

Chapter Content
● Start simple, then add complexity over rounds.
● Clarify what problem your prototype is trying to solve.
● Use rapid materials: start with paper, upgrade to digital or plastic.
Detailed Explanation
The first step in the iterative prototype cycle is to build your initial prototype. Begin with a simple version that addresses the primary problem you aim to solve. This could mean using basic materials like paper for sketches or cardboard for a model. The key is to create something quickly, so you can visualize your ideas without getting stuck on details. As you refine your prototype, you can gradually add complexity, incorporating features and materials that reflect your evolving understanding of the problem.
Examples & Analogies
Imagine you're building a model of a treehouse. First, you might sketch a rough outline on paper. Once you have that, you might use cardboard to create a basic structure, focusing on the overall shape rather than perfect details. Only after you see how everything fits together do you plan to add paint, decorations, or a rope ladder.

Chapter Content
● Gather feedback: classmates, teachers, potential users.
● Ask friendly questions: What works? What confuses? What would you change?
● Observe reactions and record feedback—both verbal and nonverbal.
Detailed Explanation
After building your prototype, the next crucial step is to test it. This involves sharing your prototype with others to gather valuable feedback. You can ask specific, friendly questions to guide the feedback, such as what works well, what is confusing, and what suggestions they have. It's also important to pay attention to nonverbal cues, like facial expressions and body language, as they can provide additional insights into how users are interacting with your prototype.
Examples & Analogies
Consider a chef who creates a new recipe. Before letting guests try it, they would taste it themselves and might ask friends what they think. Their friends might say, 'It's a bit too salty,' or 'I love the spice!' This feedback helps the chef improve the dish before serving it to a larger audience.
Step 3: Improve

Chapter Content
● Analyze feedback for patterns.
● Combine positive reactions (“warm”) with improvement notes (“cool”).
● Adjust design: structural changes, visual tweaks, or functional enhancements.
● Prepare for the next build → test cycle.
Detailed Explanation
Once you have collected feedback, the next step is to analyze it carefully. Look for patterns in the responses—what did most people say? It's important to distinguish between positive feedback ('warm') and suggestions for improvement ('cool'). Use this information to make informed adjustments to your prototype, whether that's changing the structure, altering visual designs, or enhancing functionality. Once you've implemented the improvements, you'll be ready to go through another cycle of building and testing.
Examples & Analogies
Think of a video game developer. After releasing a beta version, they collect player feedback. If many gamers love the story but find the controls confusing, the developers might revise the controls for clarity while keeping the beloved storyline intact. This process helps them improve the game before the final release.

Detailed Explanation
An effective iterative cycle in the classroom involves several days of activity focused on refining prototypes. On Day 1, students create a simple paper sketch accompanied by role-playing to visualize how users interact with their designs. On Day 2, they collect feedback and then improve their designs based on that input. Day 3 introduces higher fidelity by moving to digital or foam prototypes, followed by another round of testing. By Day 4, they work towards creating a high-fidelity version, like a detailed digital model or a 3D print. Finally, on Day 5, they reflect on the changes made throughout the week and share their final designs.
Examples & Analogies
Imagine a group of students designing a school fundraiser event. First, they brainstorm ideas (Day 1), gather thoughts from teachers and peers on what might work (Day 2), create a planned outline or digital flyer (Day 3), refine it into a polished presentation (Day 4), and finally present their ideas to the school board (Day 5). Each step helps them improve their concept based on feedback, ensuring a successful event.
