Many businesses skip high-fidelity prototyping because they consider it an unnecessary expense. However, a recent survey by Rollbar revealed otherwise. According to the survey, over a third of developers spend 25 to 50% of their time fixing software bugs.

Debugging causes project delays and increases production costs. In fact, out of the billions of dollars that go into global software production annually, debugging alone gobbles up about half.

You can avoid such costs and complications by prioritizing user testing during product development. However, without high-fidelity prototyping, you cannot conduct user testing during digital product development.

What is high-fidelity prototyping?

High-fidelity or hi-fi prototyping helps verify a digital product’s design and functionality are ready for the market. It involves building high-fidelity prototypes - preliminary, interactive prototypes that closely simulate a final product's look and functionality.

Hi-fi prototypes for digital products are typically computer-based mockups that support user interaction. The interactive prototype will have realistic graphics, animations, clickable buttons, menus, and other elements that will appear in the finished product.

Product developers allow stakeholders and users to test drive the prototype to identify if it delivers value. High-fidelity prototyping also facilitates identifying UX and UI design issues to fix before investing in building the final product.

Without hi-fi prototyping, you will have trouble collecting true human performance data regarding UI/UX design and functionality. Neglecting to gather and analyze such data will lead to a blind product development process. Such a process puts you at high risk of building a finished product with usability and aesthetic issues. Don’t forget that 88% of users are unlikely to return if a website or app has bad UX.

High fidelity prototyping versus low fidelity prototyping

The core difference between high fidelity and low fidelity prototypes comes down to the branding. Low fidelity prototypes are created in black and white so that the UX designer can focus on the user flows, withouth fussing with colors, the design of each element, the product logo, etc. 

Here’s an example of a low fidelity prototype:

After an initial round of user and stakeholder feedback, the UX designer will then bring the prototype to life with branded colors, fonts, and elements.

Why is high-fidelity prototyping important?

High-fidelity prototypes accurately represent how your final product’s user interface and user experience will look. Since the prototype looks and behaves like live software, users can interact with it normally and provide clear feedback about their experience. Their feedback will provide valuable insights into product design elements you should remove, keep, modify, or fix.

You can perform high-fidelity prototyping at various stages of product development. However, since it’s expensive and time-consuming, most design teams save hi-fi prototyping for the final stages of user testing before launch. If you can afford it, you can make hi-fi prototypes during the early stages of product development to test design concepts and user interface variations.

Benefits of high fidelity prototyping

There are tons of benefits to high fidelity prototyping, but at the end of the day, they ultimately come down to these essential competitive advantages:

  1. Reduce business risk - You can greatly reduce the risk that you will invest tens or even hundreds of thousands of dollars into a product that doesn’t work. 

  2. Increase the probability of success - By the same token, you’ll improve your chances of building a product that the market wants.

  3. Find product-market fit - You can gain a lot more clarity on your product-market fit by engaging with real users and different user segments during the testing phase.

Risks of not doing high-fidelity prototyping

If you do, you will save money during product development and feel like the smartest person in the room. However, down the road, you are likely to face the following problems, which will cost far more than you saved:

  1. Design flaws and usability issues: Skipping high-fidelity prototyping can lead to undetected design flaws and usability issues. Users will experience these issues after you release your finished product, resulting in low user satisfaction and a tarnished brand image. Not many brands, especially new ones, can recover from a bad product launch.

  2. Lost revenue: Instead of making money from your launched product, you could end up spending money fixing problems you could have spotted during high-fidelity prototyping. Investing in high-fidelity prototyping will reduce the risk of facing such a costly problem.

  3. Lack of user interest: High-fidelity prototyping will reveal if your product is something your target users want. It will help you avoid investing time and money to build a product you cannot sell.

In summary, skipping high-fidelity prototyping increases your likelihood of building a less effective, sellable, and user-friendly product. SaaS brands that make this mistake end up losing revenue and customer trust.

How does high-fidelity prototyping fit into the development process?

Product development processes typically vary between SaaS businesses and products. However, the process will still follow a general path, starting at ideation and ending with a product launch. Let’s look at the stages of SaaS product development, so you'll see where and how high-fidelity prototyping fits into the process.

How high-fidelity prototyping fits into the development process

1. Ideation

Ideation is production team members brainstorming what the product should be and how it should work and look. Besides brainstorming ideas with your team, you can get more ideas through target market research, such as customer interviews.

Your research will provide insights into the problems your target audience wants solved and how they want the solution to work. You can use the insights to come up with a product design that features the functionalities your target users desire.

2. Low-fidelity prototyping

After identifying promising ideas and eliminating unnecessary ones, you can start developing concepts for the product. Developing product concepts involves creating low-fidelity prototypes, such as simple wireframes and mockups that represent how your product will look.

Your wireframes and mockups can be as simple as a rough sketch paper prototype.

paper prototype

Alternatively, build your rough prototype with a low-fidelity prototyping tool like Balsamiq.

Low-fidelity prototyping provides a picture of how your proposed product will look so you can decide if your design ideas make sense. You can also use the prototype to test and refine basic design concepts. Once your low-fidelity prototype makes sense, you can transition to high-fidelity prototyping.

3. High-fidelity prototyping

Low-fidelity prototyping helps you avoid investing time, money, and resources into building a flawed high-fidelity prototype. Unlike low-fidelity prototypes, which are not interactive, high-fidelity prototypes are interactive, meaning you can click buttons and navigate the interface.

Since hi-fi prototyping requires more money and time, do not start it until lo-fi prototyping has given you a clear picture of how your UI/UX design should look. UI/UX design will include the visual design of your product and the layout and function of your product’s interactive elements. Once you have these details, you can build a high-fidelity prototype to test:

  • UI elements, color schemes, and copy

  • Transitions, animations, and effects

Share the prototype with users and stakeholders to see how users respond to the design and confirm if the product delivers value. After gathering user feedback with your first hi-fi prototype, you can make other iterations that incorporate the feedback.

4. Development

Once you have a high-fidelity prototype that effectively satisfies user needs and meets design requirements, you can start developing version one of your product. The development process will involve building and optimizing your product for the market.

After fully developing and testing the product, you can launch and monitor it. Monitoring the product’s performance in the hands of end users will help you identify opportunities for improvement and additional features.

10 questions to ask users about your high fidelity prototype

Make sure to give your testers time to explore your prototype on their own. Then ask them these questions to help you clarify whether or not your idea has wings.

Prototype user testing questions:

  1. What are you currently using to manage these sorts of tasks?

  2. Would you be willing to pay for this product?

  3. What features does the product need to have for you to pay for it?

  4. What would you be willing to pay for this product?

  5. How hard would it be to migrate from your current system or processes?

  6. What would prevent you from making the switch?

  7. Would using a product like this be a high, medium, or low priority?

  8. Does the prototype include any features that aren’t important?

  9. If you were to purchase the product, who at your company would use it?

  10. If you were to purchase the product, what outcomes or results would you need to achieve in order to get ROI from the purchase?

High-fidelity prototyping examples

If it’s your first time hearing about high-fidelity prototypes, you probably would like to know what they look like. Below are four screenshots from a high-fidelity prototype we created for a client. It’s a prototype of an app for managing coffee bean inventory and scheduling roasts.

Example 1

high-fidelity prototyping

The above screenshot shows the welcome page of the high-fidelity prototype. It resembles a finished product and is more detailed than the below low-fidelity prototype we made for the same product.

lo-fi prototype

The elements seen in the hi-fi prototype will all appear in the finished product. Unlike in a lo-fi fidelity prototype, these elements aren’t just for show. You can click on most of them to experience user flow within the app. For instance, clicking the Inventory tab will take you to our second example - the inventory page.

Example 2

high-fidelity prototyping example

The inventory page of the high-fidelity prototype clearly shows how users can monitor the amounts of green coffee beans remaining, roasting time left, and more. Also, you can filter the inventory page by selecting All, Green (unroasted coffee beans), or Roasted. The prototype page is interactive, allowing users to experience the system fully.

Example 3

high fidelity prototype example

This example shows what happens after clicking the Create Roast Schedule button. On this page, you can queue different coffee bean types and set the quantity to roast. The quantity you select will determine the Roast Time, and the system automatically updates the Roast Time as you adjust the quantity.

Another vital feature on this page is the Trend row. The row reveals if a specific bean type is currently in high or low demand. You can use this information to forecast how long your current stock for each bean type will last.

Example 4

hi-fi prototyping example

The final example shows the last page of the prototype app, which offers a summary of completed scheduled orders. The page will update as each order completes.

9 tips for high fidelity prototyping

To make your high fidelity prototypes more effective, follow these advanced tips. 

1. Use a collaborative, virtual prototyping tool

It’s a good idea to use a collaborative tool designed for creating UX prototypes. This way, you’ll have features like notes, comments, and real-time feedback and interactions to help you collaborate as a team. 

2. Incorporate strategic branding in your high fidelity prototype

Make sure that your UX design time goes all out when it comes to branding. Know what your target audience wants and cares about. 

Here are a few different design styles to consider for your software’s interface:

  • Minimalist

  • Corporate

  • Futuristic

  • Vintage

  • Grungy

  • Cartoonish

Especially for B2B products, your UX can make or break your business. If all of your competitors are going for a boring look, you can really stand out with something bold or whimsical.

3. Focus on the most critical user flows

You need to create a screen for every aspect of your planned product, but you should prioritize the most critical user flows, including signing up, logging in, and viewing your dashboard. Make sure to also create designs for your pillar features—these represent the user flows for important tasks like sharing a photo, reviewing a report, designing a GIF, etc. 

Your pillar features are the ones that help users achieve critical tasks. These features are your bread and butter and the key reasons why users engage with and pay for your product. 

If you’re not sure what your pillar features are, make sure to check out our guide on creating a product vision.

4. Maintain consistency in design elements

Make sure that you maintain as much consistency as possible in design elements. 

Throughout user flows, your fonts, colors, and styles should remain consistent for various elements. For example, all of your tooltips should use the same font color and size, while all of your “Next” or “Submit” buttons should have the same button shape, color, shadows, etc. 

5. Optimize for performance

Because they incorporate rich designs, high fidelity prototypes can be very resource-intensive. Make sure to optimize the images, animations, and other assets so when it comes time for user testing, the tester can engage with the prototype easily and not have to wait for items to load. 

6. Use realistic content

To make your user testing sessions as informative as possible, it’s important to use realistic placeholder content. If you just add a bunch of gobbledygook, the user will have a very hard time understanding the product and its value. 

For reports and analytics dashboards, incorporate data with realistic numbers. For design platforms, include images that reflect the skill level of your target audience. 

7. Incorporate microinteractions

It’s a good idea to add microinteractions to your user flows. Microinteractions refer to hover effects, button animations, and loading indicators. 

When there are interactive elements, users will get to experience the feeling of really using the product—even though they’re just clicking through the prototype screens. 

8. Record user testing sessions

Make sure to record user testing sessions using a platform like UserTesting. It offers features for recording both in-person and online sessions. You can also crowdsource testers that match your ideal user criteria. 

To host a successful session, share your prototype with the tester, and do not explain anything. Allow them to click through the screens and give their impressions without any guidance. Then, you can ask them questions to clarify any of their statements or dig into which features matter most. 

9. Continue to create prototypes for important new features

After you’ve validated your initial prototype, it’s time to build the MVP. Then, you’ll launch that to your beta users, reiterate, and launch it to your target audience at large.

But that doesn’t mean prototyping is done. You should continue to develop high fidelity prototypes for new products, important features, and additional user flows. If you’re adding new functionality (not just making a small to change to an existing user flow), then that means it’s time to create a new prototype and test it with users.
