The perfect prototype is the one that’s imperfect. Time and time again, new founders will make excuses like, it's not ready yet”, or “I just want to add a few more things to it” to explain why they haven’t launched their prototype yet. This mentality has slowly suffocated many a startup.

The most frequent mistake people make when producing prototypes is over engineering it. Whether it's a SAAS product, a piece of software or a physical object, people tend to spend a lot of time and resources building and perfecting their first prototypes, despite knowing these prototypes are meant to be less than perfect. As a result, prototypes are sat on for months, often accruing upwards of tens of thousands of dollars in development costs. Oftentimes, project teams run out of resources or motivation before even releasing their first iteration.

I get it though. It's a natural instinct to avoid the potential embarrassment that comes from presenting someone with an ugly, unfinished or half-baked product. Many also wish to test as many different features as possible to give people a more 'complete' experience.

The Most Common Prototyping Error Lies in Striving For Perfection

However, over-engineering, over-thinking and hesitation kill an early prototype's effectiveness to fill its primary function - get market validation and validated customer learnings as quickly as possible. Prototypes are built 'for learning, not scaling', David J Bland writes, so it's important to get out of the mentality of 'building to build'. As Tim Brown says in Change By Design, "prototypes should command only as much time, effort, and investment as is necessary to generate useful feedback and drive an idea forward”. The more a founder or project lead has invested into it, the less likely they are to listen to and benefit from constructive feedback.

Prototypes are meant to be cheap, dirty and quick

Google is not a company lacking resources. When we ask people how long they think it took Google to prototype their (admittedly now shelved) Google Glass, the most common answer is a couple of months. But Tom Chi, head of Google X, revealed the team built a Google Glass prototype in only one day, using a coat hanger, a piece of plexiglass, and a pico projector connected to a laptop. The purpose of the prototype was to simply test what the experience of having digital information overlaid on the physical world, a la ‘minority report’ style. It wasn't particularly ergonomic, nor was it good looking, but it did the one job quickly and cheaply with bits and pieces lying around.

Here's a few ways you can build quick and dirty prototypes on the cheap.

1. Landing Pages

Landing pages are simple, usually one-page websites where visitors can find out more about your product or service, and leave their email as an expression of interest. They serve as great prototypes as it allows you to test whether people would be interested in your product, as well as onboarding them as your first potential customers.

There are a bunch of drag-and-drop landing page builders which take all the coding out of the website building, meaning it's easy to whip up a simple, good-looking and functional page in less than an hour. The fact a lot of these services don't cost money unless you want all the bells-and-whistles means these landing pages might only cost you some time.

One of the best examples of a landing page being used as a prototype is with social media scheduling tool, Buffer. Before a working version of Buffer was built, founder Joel Gascoigne built a landing page explaining in three lines what Buffer did, what the pricing would be, and an option to sign-up on the spot as if Buffer was live. In this instance, he was trying to test whether people would pay money for an automation software like his, and it was only after positive results, did he start building the product.

Look for Instapage, Unbounce and Launchrock!

2. Paper Prototypes

Paper prototypes are a great way to test apps and usability. Take a few sheets of paper, and draw how you imagine the app (or program) might look (think different screens, buttons and even some text). You can then take these pieces of paper and show people what the app might look like, ask them to interact with the 'screens' and show them what might happen when they 'press' on a button.

This is a great way for you to explain what your idea does, how it might work, and elicit feedback not only on the idea, but on the user experience as well.

Want to take that to the next level? Apps like Pop App allow you to take photos of your sketches and hotlink the buttons to relevant screens, allowing your testers to interact with your idea within a phone, giving an even more immersive experience. If you're looking for something even more realistic, you can use programs like Sketch to digitally design what the app looks like.

3. 3D Printing

3D Printing is an absolute boon for people looking to build a physical product. While it's not a medium for mass manufacturing or producing polished products (yet), it's perfect for rapid-prototyping and getting a first product into your customer's hands. Prints can give you customers a way to see what the product will look and feel like in their hands.

"But", I hear you say, "3D printing requires 3D CAD design, which I don't know how to do! And I don't have a 3D printer lying around at home!" That's ok too. Services like Tinkercad allow you to do simple 3D CAD renderings using an easy-to-use drag-and-drop interface. In terms of printing, there'll be often local services that can print 3D files off for you for cheap.
