Welcome back to our "Design Decoded" series!
Today, we delve into the often overlooked but crucial task of reviewing design mockups. Whether you're a developer struggling with inconsistencies in mockups or a designer frustrated by the lack of clarity in feedback, this article is for you.
We'll explore why investing time in thoroughly reviewing mockups can save everyone time and headaches down the line.

We'll explore why investing time in thoroughly reviewing mockups can save everyone time and headaches down the line.

The Misconception of Mockup Reviews
At first glance, you might think that mockup reviews are just another unnecessary step in an already lengthy design process. After all, mockups are just preliminary versions of the final product, right? This misconception can lead to significant issues during the development phase.
Let's consider what usually happens when mockups aren't properly reviewed.
Designers hand off their creations, hoping that developers will understand their vision and translate it into a functioning application. Developers, on the other hand, are left to interpret these designs, often leading to a mismatch between the designer's intent and the final product. The most likely result will be a chaotic codebase with a lot of inconsistencies. The team will have to spend additional weeks fixing these issues, delaying the project and increasing costs. This gap in understanding will only result in wasted time, rework, and frustration on both sides.

The Role of Mockup Reviews in the Development Process
Mockup reviews serve as a critical bridge between the design and development stages of a project. Without them, designers and developers operate in silos, which can lead to miscommunications and errors. Here are some of the essential components of an effective mockup review process:
What happens if we take our time and review mockups before coding?
The team identifies potential issues early, clarifies ambiguous elements, and ensures that the design is consistent and functional across all devices. The development phase proceeds smoothly, with fewer revisions and a faster time to market.
- Consistency: Ensure that all elements follow the same design language. This includes colors, fonts, button styles, and spacing. Inconsistent elements can confuse users and detract from the overall user experience. I wrote a quite huge article on that topic here: Clik!
- Functionality: Verify that all interactive elements, such as buttons, inputs and links, are clearly marked and their intended behaviors are documented. This helps developers understand how the application should behave and prevents guesswork.
- Responsiveness: Check how the design adapts to different screen sizes. A mockup that looks great on a desktop might not work well on a mobile device. Ensuring that the design is responsive saves time during the coding phase. It was explained here: Click!
- Accessibility: Review the design for accessibility considerations. This includes color contrast, font size, and navigation elements. Accessible designs are not only ethically important but also often legally required. Check out more about accessibility here: Click!
- Clarity: Make sure that all annotations and specifications are clear and detailed. Ambiguities in the mockup can lead to incorrect implementations and additional rounds of revisions. So for example if the design team puts a number on a user's profile picture they should also add a comment about what that number means - is it a notification that the user got a message? Or maybe it’s a number of information that is missing on the user's profile?
- Edge cases: While creating mockups, especially ones that include forms, inputs make sure to cover all edge cases. If you only give short examples (name - Jane Doe, number - 123) there is a big chance that developers won’t add code to secure longer cases. See our article about responsive design: Click!
- Error handling: It’s very common that when developers first get mockups they only include “happy path” - I wrote about it here: Click!. If that’s the case, make sure to go back to the design team and ask them to include error and loading states. It speeds up the development process significantly.

The Benefits of Thorough Mockup Reviews
Investing time in reviewing mockups thoroughly can lead to several long-term benefits:

Happy coding/ Happy designing!
- Reduced Development Time: Clear, detailed mockups provide developers with all the information they need, reducing the time spent on clarifications and revisions.
- Improved Quality: Consistent, functional, and accessible designs lead to a better user experience, enhancing the overall quality of the application.
- Cost Savings: By identifying and addressing potential issues early in the design phase, you can avoid costly reworks and delays during development.
- Enhanced Collaboration: Regular mockup reviews foster better communication between designers and developers, promoting a collaborative environment where everyone's input is valued.
