Speed Wins: Mastering Product Design with Rapid Iterative Testing

7 min read


Let’s discuss a simple yet powerful way to improve digital products: quickly testing and tweaking as we go. This technique isn’t just any technique – it’s one that companies like Yahoo! and Google use to succeed. It’s called the RITE Method, which stands for Rapid Iterative Testing and Evaluation. It’s all about making fast changes based on what works and what doesn’t.

Imagine this: you’ve got an idea, a prototype, and a burning desire to create something users will love. But there’s a snag. Traditional testing methods are like molasses on a cold day—slow and sticky. Enter rapid iterative testing, a method as dynamic as your ideas, ensuring user feedback propels your product forward faster.

What’s the Big Deal with Rapid Iterative Testing?

Here’s the lowdown: The RITE method is about making swift, smart changes as soon as a usability hiccup pops up. Developed by the sharp minds at Microsoft Game Studios, including Michael Medlock and his colleagues, this method was born out of the need for speed in game development, where waiting isn’t an option.

But rapid iterative testing is not just for games. With it, any product can be a star. Luke Wroblewski, a respected product designer and innovator who has worked at Yahoo! and Google, swears by it. His teams have sprinted through product design sprints using RITE to gain a profound understanding of their projects and the landscapes they’re navigating.


Many Benefits to Drive Your Product, Research, and Team Forward

Rapid iterative testing, or RITE, offers many benefits that can significantly improve product development and user experience (UX) design. Here’s why it’s become a go-to method for companies looking to stay agile and innovative:

Product Benefits

  • Faster Feedback Loop: The hallmark of RITE is the ability to test and modify quickly. This means you’re constantly in tune with user feedback and can implement changes immediately, leading to a more refined product in less time.
  • Improved Product Quality: Continuous feedback and immediate adjustments result in a higher-quality end product. Each iteration homes the usability and appeal of the product, ensuring that the final version resonates well with the target audience.
  • Risk Mitigation: By identifying and addressing issues early in the process, you mitigate the risk of costly overhauls or major changes later in the development cycle, when they can significantly impact time and budget.

Research Benefits

  • Increased Efficiency: You save time and resources by not waiting to complete an entire testing cycle before making changes. This approach maximizes your team’s productivity, allowing for more development within the same timeframe.
  • User-Centric Design: RITE places the user at the heart of the development process. As users uncover issues and provide insights, the design evolves to meet better their needs and preferences, which is vital for user satisfaction and adoption.
  • More Effective Use of Research: With RITE, test data isn’t just collected; it’s actively used to drive decisions. This real-time application of insights ensures that data serves its primary purpose—to inform and improve design choices.

Organizational Benefits

  • Enhanced Team Collaboration: RITE’s iterative nature encourages better team communication. As changes are made, team members from various disciplines are brought together to discuss, troubleshoot, and innovate, fostering a collaborative environment.
  • Better Learning Curve for Teams: Teams learn faster because they immediately see the consequences of their design decisions. This rapid learning cycle leads to more experienced, knowledgeable teams adept at predicting user needs and behavior.
  • Stakeholder Engagement: Stakeholders can see progress in real time and understand the rationale behind changes, which keeps them engaged and informed throughout the product development lifecycle.

By leveraging the benefits of rapid iterative testing, companies can not only improve their products but also foster a culture of continuous improvement and user-centric design that can be a significant competitive advantage in the marketplace.

Why Rapid Iterative Testing is Your New Best Friend

Picture this: you’ve just conducted a test, and bam, you’ve got a pile of feedback that’s fresher than morning bread. No need to wait for a full study to wrap up; you jump right in and start fine-tuning your prototype. It’s like conversing with your users, where they point out what’s not working, and you can say, “Got it, let me fix that,” in real-time.

And here’s a kicker that’ll knock your socks off. Teams using platforms like Helio can skyrocket their usability feedback within hours. Why? Because Helio has rolled out the red carpet for rapid iterative testing with the following:

  • Pre-gathered targeted audiences (like having a focus group on speed dial),
  • Usability tools baked right into the surveys (think of it as your Swiss Army knife for testing),
  • Super simple test question setups (it’s so easy, a caveman could do it).

How Rapid Iterative Testing with Helio Makes Products Shine

Let’s take a real-world gander at how this plays out. You’ve got a feature in your app that you think is the bee’s knees. But when you put it to the test, users are scratching their heads. With rapid iterative testing, you don’t have to wait for all the results before making changes. You tweak, adjust, and refine, then test again. Each round of feedback is a gold nugget that brings you closer to a user experience that’s as intuitive as flipping a light switch.

For instance, an ad campaign management company named Advent (based on a real customer) planned to introduce a new component to their platform, an audience page. This new Audience page provides ad campaign managers a full view of the types of people they’re currently reaching and who they’re trying to reach.

Let’s dive into the iterative testing

Since this was a new concept on their platform, Advent wanted to involve testing in their creative process of building the Audience page. Over three weeks, Advent met with their Helio support team to discuss the current state of the designs, share signals the testing results had unearthed, and plan improvements for the next round of testing:

The testing started with a prototype of Advent’s Audience page in a wireframe stage, without any elaborate visuals and displaying minimal information on the page, shown in the screenshot below.

To conduct their tests, Advent used the Gravity Score Method to establish a customer usability score as a baseline to compare future iterations against. The Helio Gravity Score Method is based on the System Usability Score (SUS) method of testing, in which participants who have just experienced a product answer a series of 10 questions to gauge their reaction to the product.

In Helio, participants were presented with click directives—prompts asking them to take action on the page based on their goals.

Once the participants are taken through the most important actions on the page, the series of 10 Likert scale questions begins.

The questions alternate between positive and negative inquiries, gauging how successful the product was at establishing good emotions and avoiding user pain points. The data output from these 10 questions is placed into the same formula used for the tried-and-tested SUS method.

Using the Gravity Score

The Gravity Score method produces a single data point to compare future iterations against, such as the 66 achieved in the first round of testing on the Audience page.

the first prototype received a gravity score of 66 from the first round of rapid iterative testing

The average Helio Gravity Score stands at 68. This indicates that this page’s initial iteration fell short of the team’s and participants’ expectations. Specifically, within the individual columns, where a high average number is desired for each question, questions 8 and 10 emerged as the most detrimental to the overall score.

Consequently, this signified a consensus among participants who strongly felt that the platform is cumbersome and demands significant upfront learning before it can be effectively utilized.

Over the next week, Advent changed its Audiences page design to increase the fidelity, target those two culprits, and reran the same Gravity Score test. Below is a screenshot of the updated prototype.

The new score of 69 confirmed the team’s direction on the Audience page. This allows them to move forward confidently toward the final iteration.

Advent completed their Audience page design with their wireframe layout set in full visual fidelity over the next week. They tested the page once more to validate their decisions.

In each round of rapid iterative testing, the prototype's gravity score improved.


The Gravity Score steadily rose to 71. The Advent team completed their Audience page designs. Backed by user data, they presented confidently to stakeholders.
