How to Prioritize Usability Issues in Testing

Struggling to prioritize usability issues? Here’s how to tackle them effectively:

When usability testing reveals a flood of problems, it’s crucial to focus on what matters most. Not every issue has the same impact on user experience or business results. Start by identifying problems that disrupt key user tasks – like completing purchases or signing up – and rank them based on their importance and ease of resolution.

Key Takeaways:

Identify Issues: Use methods like moderated testing, session replays, or eye-tracking to spot where users face challenges.
Prioritize Smartly: Use tools like the Impact-Effort Matrix or a Desirability, Viability, and Feasibility (DVF) scorecard to rank issues objectively.
Document Everything: Record user struggles, feedback, and task completion rates for clarity and consistency.
Use the Right Tools: Platforms like Jira, Trello, or Asana help track and manage fixes efficiently.
Test Continuously: Regular iterations ensure improvements meet user needs and align with business goals.

By addressing high-impact, low-effort changes first, teams can improve usability while saving time and resources. A structured approach ensures you resolve critical issues, keeping users satisfied and business performance on track.

Prioritize UX Findings by Severity

Step 1: Finding Usability Issues

Before diving into solutions, it’s essential to pinpoint usability issues and gather detailed insights into how users interact with your website. This step is about observing real user behavior – not just relying on assumptions about how users should navigate your site.

"Usability testing is a research activity designed to evaluate the usability of a website or application by observing representatives from your key audience(s) as they try to perform a set of realistic tasks using your site or application." – Department of Energy ^[4]

Start with a strategic approach. Research shows that testing with just 3–5 users can uncover about 80% of usability problems ^[4]. The key is to choose the right testing methods and document everything thoroughly.

Testing Methods to Identify Problems

Different testing methods uncover different types of issues. For example:

Moderated testing is great for understanding the reasoning behind user actions.
Unmoderated testing works well for gathering data on specific behaviors or answering targeted questions ^[2].

Testing on a live website is particularly insightful. It helps catch design flaws, navigation issues, and even technical bugs. Product Designer Mariana Anjos highlights the value of this approach:

"Testing your live website for usability is highly beneficial. You get to gather user insights continuously and use them to boost customer satisfaction." ^[1]

In-person testing can capture subtle, non-verbal cues but tends to be more time-intensive and costly. On the other hand, remote testing offers flexibility, faster results, and access to a wider audience – perfect for teams on a budget or tight deadlines.

For open-ended feedback, explorative tests are useful, while comparative tests focus on helping users choose between specific solutions. If you’re trying to understand why users behave a certain way, qualitative testing is your go-to. Meanwhile, quantitative testing is all about collecting measurable data ^[3].

Here are some popular testing methods to consider:

Session replays: Watch recordings to see where users struggle.
Card sorting: Understand how users mentally organize content.
Observation and eye-tracking: Gain insights into user focus and behavior.
Guerrilla testing: Conduct quick tests with random participants for rapid feedback.
Online tools and platforms: Efficient for remote usability studies.

Skipping usability testing can be costly. One company learned this the hard way when it launched an app without proper testing, leading to technical failures and poor reviews. They had to relaunch the app two weeks later, incurring significant expenses ^[1].

Once you’ve identified the issues, the next step is documenting them clearly.

Recording Your Findings

Good documentation is the backbone of usability testing. It ensures that issues are understood and prioritized effectively. Don’t just note that "navigation is confusing." Instead, detail which elements caused confusion, what users were trying to achieve, and how they reacted.

Create test scenarios that reflect real user goals ^[1]. Record everything, including:

Specific tasks users struggled with
Direct user feedback and quotes
Context around the problem (e.g., what users were doing before and after the issue occurred)

Document both successes and failures. Even if users complete a task, any friction points along the way still matter. Include timestamps, user comments, and any workarounds they used to reach their goal.

Testing should be a regular process. By standardizing your documentation, you’ll build a reliable resource for identifying and prioritizing the issues that have the biggest impact.

Step 2: Methods for Ranking Usability Issues

Once you’ve identified usability problems, the next step is figuring out which ones to address first. Some issues might simply annoy users, while others could push potential customers away entirely. To prioritize effectively, it’s essential to rely on structured frameworks rather than subjective judgment. Here are three tried-and-true methods to help you turn a long list of issues into a clear action plan.

Using the Impact-Effort Matrix

The Impact-Effort Matrix is a straightforward visual tool that helps you evaluate usability problems based on their value to users and the effort needed to fix them. It divides tasks into four quadrants:

Quadrant	Effort	Impact	Action
Quick Wins	Low	High	Focus on these first
Big Bets	High	High	Plan carefully and prototype
Fill-Ins	Low	Low	Save for when you have extra capacity
Money Pits	High	Low	Avoid these altogether

Quick Wins are the sweet spot – issues that deliver high user value with minimal effort. For example, tweaking a confusing button label or fixing a small but frustrating form error might fall into this category.

Big Bets are high-impact but resource-intensive fixes, like redesigning your checkout process or reorganizing your navigation. These require careful planning and testing to ensure success.

Fill-Ins are low-priority tasks that can wait until your team has extra bandwidth, while Money Pits are resource-heavy fixes that don’t provide much value and should generally be avoided.

To apply this method, gather your team and assign scores for each usability issue through a voting process. A good rule of thumb is to allow each team member a number of votes equal to half the total number of items being prioritized. Define "impact" as the value the fix brings to users and "effort" as the resources and labor required to implement it. Once completed, the matrix becomes a handy reference for prioritization in future projects.

Using a Feasibility, Desirability, and Viability Scorecard

For a more comprehensive analysis, consider using the Desirability, Viability, and Feasibility (DVF) framework. Developed by IDEO, this method evaluates usability issues from three critical angles: user needs, business goals, and technical constraints.

"IDEO’s Desirability, Viability and Feasibility (DVF) framework is a powerful tool that helps teams create successful products by evaluating three key factors separately and bringing them together." ^[5]

Desirability: Does fixing the issue address real user needs? This assessment relies on data from user research, personas, and journey maps rather than assumptions ^[5].
Viability: Does the fix align with business goals and budgets? Consider market demand, pricing, implementation costs, and potential revenue impact ^[5].
Feasibility: Can the solution be realistically implemented? Factor in technical limitations, resource availability, timelines, and legal or regulatory requirements ^[5].

To use this scorecard, rate each issue on a scale from 1 to 5 for desirability, viability, and feasibility, then add up the scores. This numerical approach makes it easier to compare issues objectively and focus on the ones with the most potential. The DVF framework also promotes collaboration across teams, ensuring that solutions meet both user expectations and business objectives.

Tracking Data with a Task Completion Spreadsheet

Sometimes, the simplest tools are the most effective. A task completion spreadsheet provides a clear, data-driven way to track usability issues and their impact.

Create columns for tasks, completion rates, time to completion, user satisfaction scores, and the frequency of specific issues. Use color coding to make patterns easy to spot – for instance, red for critical issues, yellow for moderate ones, and green for tasks users complete successfully.

This method works particularly well when paired with usability testing data. For example, if users consistently struggle to complete a key task, the completion rate alone can highlight where your priorities should lie.

Step 3: Tools and Methods for Managing Usability Issues

Now that you’ve ranked your usability issues, it’s time to take action. Success hinges on using the right tools and setting up processes that keep improvements on track.

Project Management Tools

Project management software is essential for keeping usability efforts organized. It centralizes communication, tracks progress, and ensures nothing slips through the cracks.

Jira is a favorite among agile development teams. With a 4.4/5 rating on Capterra from over 15,000 users, it’s known for its robust ticketing system and customizable workflows. It simplifies issue management, from discovery to resolution, and automated notifications keep everyone in the loop as tasks move through stages.

For teams that thrive on visual organization, Trello offers a user-friendly Kanban board, making it a great fit for smaller teams.

Asana combines visual tools with detailed task lists, making it ideal for breaking down complex fixes. It organizes work into projects, subtasks, and to-do lists, and even facilitates direct communication within the platform. With a 4.5/5 Capterra rating from over 13,300 users, it’s a popular choice for teams aiming to streamline workflows.

When choosing a tool, think about factors like ease of use, scalability, integration with your existing systems, customization options, and cost. Many platforms offer free versions, so you can test them out before committing to a paid plan. The right tool should bring your team together and simplify processes without adding unnecessary complications.

Wrike stands out for cross-functional collaboration. It offers real-time analytics, customizable workflows, and a 4.3/5 Capterra rating from over 2,700 users. Wrike’s recent acquisition of Klaxoon has added features like digital whiteboards and brainstorming tools to its ecosystem.

"Time will be saved as we learn how to transform steps created using Klaxoon’s collaboration tools into actionable tasks and projects in Wrike. We will be able to see projects in their entirety, from brainstorming to completion, in one place!" – Kendra Ciszczon, Operational Excellence Analyst, Press Ganey Associates ^[6]

Once your tools are set up, the next step is to focus on continuous improvement through ongoing testing.

Repeated Testing and Continuous Improvement

Putting management tools in place is just the beginning. Continuous testing is the engine that drives usability improvements. Iterative testing involves making small, manageable changes and validating them in cycles, allowing you to refine your product step by step.

Each round of testing delivers insights into what’s working and what still needs attention. Before starting a test, set clear goals and hypotheses. Plan your approach carefully, selecting the right methods and defining the parameters you’ll measure. By testing incrementally, you can isolate variables and better understand their impact. Once the results are in, share your findings with the team and apply successful changes across the product.

Documentation plays a crucial role here. Keeping a record of changes and their outcomes creates a knowledge base that helps your team avoid repeating mistakes and builds a foundation for future improvements.

"We did tons of user research to determine what were the models, the messages, et cetera that we were going to go live with, but it was all about the testing and iterative approach that followed that got us to where we are today. So there is a moment where you almost have to take a leap of faith and have a very solid testing plan post-launch that takes you to where you ultimately want to be, which can look very different than what you originally thought." – Ryan Daly Gallardo, SVP of Consumer Products at Dow Jones (Wall Street Journal) ^[7]

Iterative testing isn’t a one-time task – it’s an ongoing mindset. From product discovery to development and post-launch tweaks, this approach ensures you can catch and resolve issues early, keeping your product aligned with user needs through continuous refinement.

Connecting Usability Issue Prioritization with Brand Strategy

When you tie usability improvements to your brand strategy, the results go beyond just fixing user problems – they create a unified user experience that supports business growth. At ChrisRubinCreativ (CRC), we see every usability enhancement as an opportunity to address user challenges while reinforcing your brand identity. By aligning usability fixes with your brand strategy, you amplify their impact, turning each improvement into a step toward broader business success.

Building Usability into the User-Centered Design Process

Incorporating usability into your design workflow requires foresight and teamwork. The secret lies in embedding your brand vision early in the UX design process instead of treating it as an afterthought.

Regularly schedule sync meetings and workshops where UX designers and brand stakeholders collaborate to update personas, journey maps, and style guides that align with current brand goals. Equip UX teams with up-to-date brand guidelines, including mission statements, value pillars, and strategic objectives. Early prototype reviews are essential to ensure they reflect your evolving brand vision. Tools like mood boards, style guides, and design systems tied to brand guidelines help maintain consistency throughout the design process. By measuring UX success through metrics like engagement rates in newly targeted demographics, you can ensure that your design efforts align with your brand’s growth objectives.

Matching Fixes with Brand Growth Goals

Every usability improvement is a chance to strengthen your brand identity and support business growth. The challenge? Identifying which fixes will have the most significant impact on both user experience and brand perception.

Start by mapping user goals to business objectives. Collect direct user feedback and test new UI elements early, tracking outcomes with metrics like Net Promoter Score (NPS) and customer retention. Interviews and focus groups can help uncover gaps between user perceptions and your brand aspirations. Use this insight to prototype and test UI elements that reflect your brand’s evolving vision, prioritizing fixes that align with these initiatives.

Monitor UX outcomes using metrics such as NPS, customer retention, and brand equity. Sentiment analysis tools can help you gauge how UX changes influence user reviews and social media discussions. Focus on developing features that align with new brand initiatives, delaying updates to legacy elements that no longer fit your strategy. Provide stakeholders with detailed reports that connect UX efforts to measurable brand outcomes. This approach ensures every usability fix not only resolves a problem but also strengthens your brand’s position in the market.

Finally, build adaptable UX frameworks that can evolve alongside your brand, ensuring long-term alignment and scalability.

Conclusion: Key Points for Better Usability Prioritization

Turning usability testing feedback into a clear plan for improvement is essential for creating better user experiences. A simple three-step process – identifying problems through testing, ranking them with structured methods, and resolving them using the right tools – lays the groundwork for meaningful changes that can also boost business performance.

Structured frameworks take the guesswork out of prioritizing fixes. They help you focus on quick wins – those changes that deliver big results with minimal effort. By using objective scoring systems, you can ensure transparency in decision-making and keep your team aligned on what matters most.

Collaboration across teams adds even more value. When designers, developers, and business stakeholders work together, you get a mix of insights that leads to smarter, more balanced decisions.

The financial upside of prioritizing usability is hard to ignore. Research shows that every $1 spent on UX can return anywhere from $2 to $100, depending on the project’s scope^[8]. Addressing usability issues early can also cut development costs by up to 50% by preventing expensive fixes after launch^[8]. These numbers highlight why usability should be a priority in your broader business strategy.

To stay effective, usability prioritization needs to evolve alongside user needs and business goals. Regularly reviewing your framework and tracking metrics like task completion rates, error rates, and conversion rates ensures you can measure the impact of your improvements. At ChrisRubinCreativ (CRC), we emphasize aligning usability efforts with your brand’s goals. Doing so not only solves user pain points but also strengthens your brand identity and drives measurable growth.
