What is a Prototype?
💡 “A prototype is a test version of your product before full-scale manufacturing or development.”
Prototypes help in:
✅ Visualizing concepts before investing in production
✅ Testing functionality & usability at early stages
✅ Reducing costs by fixing design issues beforehand
📌 Two Major Types:
- Low-Fidelity (Lo-Fi): Quick & rough prototypes for early testing
- High-Fidelity (Hi-Fi): Detailed, functional prototypes closer to the final product

What is a Low-Fidelity Prototype?
📌 “Fast, cheap, and used for initial idea validation.”
✅ Made using: Sketches, paper models, cardboard, 3D-printed parts
✅ Best for: Brainstorming, concept testing, quick user feedback
✅ Cost: 💲 Very Low
✅ Speed: ⚡ Very Fast
🔍 Example:
Before developing the first iPhone, Apple created cardboard phone models to test screen sizes.

What is a High-Fidelity Prototype?
📌 “Closer to the final product, used for detailed testing.”
✅ Made using: CNC machining, injection-molded parts, functional electronics
✅ Best for: Usability testing, investor pitches, pre-production evaluation
✅ Cost: 💲💲💲 Higher
✅ Speed: ⏳ Slower but more accurate
🔍 Example:
Tesla’s early Model 3 prototype was a full-scale working vehicle to test aerodynamics and battery integration.

When to Use Each? (Comparison Table)
💡 “Not sure when to use Lo-Fi or Hi-Fi? Here’s a quick comparison.”
| Feature | Low-Fidelity | High-Fidelity |
|---|---|---|
| Purpose | Concept validation | Functional testing |
| Material | Paper, foam, 3D prints | Metal, plastic, electronics |
| Cost | 💲 Low | 💲💲💲 High |
| Speed | ⚡ Fast | ⏳ Slower |
| Best For | Early-stage design | Final-stage testing |

Choosing the Right Prototype
🛠 Use Lo-Fi When:
✅ You’re in early brainstorming & concept validation
✅ You need quick feedback from users & stakeholders
⚙️ Use Hi-Fi When:
✅ You need precise testing before mass production
✅ You’re presenting to investors or manufacturers
📌 Final Tip:
Start Lo-Fi, refine your design, then move to Hi-Fi for final validation.
