Find out what a prototype is; how it can save you time, money, and resources through feedback; and other benefits of prototypes.
A prototype is a physical or digital model of a proposed product.
The prototype offers several benefits, including the ability to save resources, gather useful feedback, and attract investors.
According to Merriam-Webster, “prototype” means creating a model you can use to pattern something based upon, with its prefix, proto-, coming from the Greek language [1].
Having a prototype means you can get immediate feedback after introducing it, and you can use that feedback to make changes before your project progresses to more extensive stages of the product development process.

A prototype is a model of a proposed product. It transforms the original concept into physical or digital form. It serves as a small-scale example of your product to confirm its feasibility and allows you to make the required tweaks to ensure it is viable before investing more time and resources. It can be as simple as a quick design or a few specific parts of a product created for early-stage testing.
A prototype is also a great tool for gathering feedback from potential users. This feedback can help designers make changes and fix manufacturing and development issues before moving forward in the product creation process.

According to Merriam-Webster Dictionary, a prototype refers to “an original model on which something is patterned.” The prefix prot- or proto- comes from the Greek language and means “first formed” or “first in time.” [1]
Developing a successful prototype has many benefits, including saving resources, inviting feedback, and attracting investors. A prototype is a sample rather than a complete product ready for trials, allowing you to detect design flaws and potential areas for improvement early, saving time and money. Consider these three key benefits when creating a prototype:
It is less expensive to discover flaws early in the process than when development begins, so creating a prototype can save costs as the project progresses to more expensive stages. A prototype can help you identify which areas of your product work so you can spend your time and focus your funds on them. You may find flaws otherwise hidden, such as differences in the way materials behave or stress points that you overlooked in the design process, and your prototype enables you to discover ways to optimize your product before it hits the market.
You may even discover that your prototype won’t work and decide to forgo the concept altogether. In this case, you can save time and work by scrapping your original concept and using what you've learned from the unsuccessful attempt to focus on a better solution or to move on to something else. Even in this case, the failed prototype can save you time by switching your focus to a different concept.
Gaining feedback on your prototype from potential clients or users can greatly enhance the final outcome of your product. When presenting a prototype to your target audience, ask for their thoughts on what works and on any areas where they think improvement is necessary. Working with an actual prototype allows users to give immediate feedback. Even if you choose not to implement their critiques, you can gain insight into potential areas of concern.
Using feedback from potential users can help you attract investors and build credibility with them, which is especially important for start-ups. Without seeing actual interest in a product and its ability to deliver, investors may not be able to properly measure your product’s feasibility in the market. With a prototype, investors can see the product’s potential.
