In our design thinking series, we’ve covered the first three phases: Empathise, Define, and Ideate. These stages are all about understanding the user, identifying their needs, and coming up with a variety of ideas to solve the problem.
Now, let’s move to the fourth phase: Prototyping, where we bring ideas to life in a way that we can test, improve, and eventually make ready for actual use.
What Is Prototyping?
Prototyping is the process of creating a simple, physical model or version of your idea. It doesn’t need to be perfect or fully functional; its purpose is to learn, explore, and see how the idea might look or work in real life.
By making a physical or digital representation of the idea, you can test it, find out what works and what doesn’t, and make improvements. Prototyping allows you to take risks and experiment because you know this model is just a starting point, not the final product.
Prototyping is also a flexible and iterative process, meaning you can create multiple versions, improving the idea with each version. James Dyson, the inventor of the famous Dyson vacuum, is a perfect example of perseverance in prototyping.
Before creating his groundbreaking product, Dyson went through over 5,000 prototypes—5,126 to be exact. Each prototype taught him something new, and with every failure, he was one step closer to success. His journey shows how essential the prototyping phase is in turning ideas into revolutionary products.
Why Prototyping Is Important
Prototyping is essential in design thinking for startups, entrepreneurs, and makers.
It allows you to spot problems and make changes quickly, minimising risk by identifying and addressing potential issues before committing to full-scale production.
Rather than investing lots of time and money in a final product right away, you can also use a prototype to see if the idea actually meets the needs of the users. Through user testing, you can gather real feedback, refining the product to better meet market needs and reduce errors.
Importantly, prototyping helps make abstract ideas tangible, so you can see, touch, and experience them. That way, you can showcase your vision to investors, giving them a clear understanding of the product and increasing the likelihood of securing funding.
This iterative process not only saves time and resources but also boosts confidence in the final product, ensuring it’s as effective and user-friendly as possible. Prototyping ultimately turns ideas into actionable insights, making it a powerful tool for anyone looking to innovate and succeed.
Types of Prototyping: Low Fidelity vs. High Fidelity
-
Low-Fidelity Prototyping
Low-fidelity prototypes are simple and basic models. They’re quick and inexpensive to make and usually use materials like paper, cardboard, or simple crafting supplies. These prototypes don’t have all the details or functions of the final product; they just capture the main idea of the physical product. This kind of prototype helps you understand the shape, size, and basic structure without worrying about details like materials or strength.
For example, if you’re designing a new chair, a low-fidelity prototype might be a rough model made of cardboard or clay.
Low-fidelity prototypes are useful because they are easy to create and modify. If you find out an idea isn’t working, you can change it without much cost or effort.
-
High-Fidelity Prototyping
High-fidelity prototypes are much closer to the final product. They are detailed, use realistic materials, and may include functional parts. High-fidelity prototypes can be created with materials closer to what the final product would use, such as wood, metal, or plastic. These prototypes are useful for testing the feel, usability, and appearance of the product in a realistic way.
Continuing with our new chair example, a high-fidelity prototype might be built using real wood and metal fasteners to see how sturdy it is and how it looks in real life.
High-fidelity prototypes allow users to experience the product in a way that’s very close to reality. This type of prototype is used in later stages, where specific details matter.
In this article, we explored the essential role of prototyping in bringing ideas to life, particularly in distinguishing between the early stages of a concept and the final product. Understanding the value of both low-fidelity and high-fidelity prototypes is key to refining designs and meeting user needs.
In our next article, we’ll dive deeper into the differences between low-fidelity and high-fidelity prototyping, exploring specific methods and how they work in practice.
