What exactly needs to be checked before the design draft is delivered for development? The true UI QA should be completed before "Ready for Dev"

"Ask me if there are any problems during development" is not a design delivery process. Before truly entering Ready for Dev, designers should first ensure that the page structure, components, state, responsiveness, exception data and copywriting have reached a definite level that can be implemented; otherwise, most of the problems in the development stage will turn into rework.

01 Confirm the requirement status first instead of checking the pixels first

No matter how complete the page visuals are, if the product rules are still changing, it does not meet the "Ready for Dev" standard. First, confirm that the necessary decisions have been made regarding the scope, process, data, permissions and key copy.

Figma's current Dev Mode provides the Ready for dev status and change comparison precisely to make "implementiable" a definite state, rather than defaulting to development just because the file exists.

02 Check all key states, not just the normal success page

Loading, Empty, Error, Disabled, insufficient permissions, overly long content, zero data, maximum data, and network failure should all be designed or have clear rules.

If the developer asks, "What if there is no data?" and the designer is thinking about it for the first time, it indicates that QA has occurred too late.

03 Components need to confirm that they come from the correct library and version

The buttons that look the same on the page might be one from the Design System and the other a Frame temporarily drawn by the designer. Duplicate code will be generated during the development and implementation.

Before delivery, check component instances, variants, tokens, and deprecated components to ensure that the page uses a maintainable structure.

04 For the responsive type, the submission rules are required, not just two screenshots of the dimensions

How does the desktop 1440 change between the mobile phone 375? When to wrap lines, hide, fold, or change to two columns? All of these require rules.

Development should not fill in the layout of 1024, 768, and 430 through guesswork. Key breakpoints and behaviors should be clearly marked.

05 Real content and boundary data must be included in the design draft

Short examples like "User name" and "project name" cannot expose the problem. Test the longest product name, Chinese and English, blank fields, four-digit amount, and extremely long labels.

Content adaptation is part of the UI, not about modifying the CSS after going live.

06 The interaction effect should specify the trigger, duration and degradation

If only one screen recording is sent, the developer cannot know the easing, delay and trigger conditions. Figma 2026's Motion/Dev Mode already supports viewing some animation times and codes, but the team still needs to clearly define the behavioral norms.

At the same time, explain the alternative strategies for Reduced Motion, mobile devices and low-performance devices.

07 Basic items for accessibility should be checked during the design QA stage

Color contrast, Focus, touch size, semantic tags, form errors, and keyboard paths are not details that developers can handle conveniently.

The design should at least define the visual and interaction requirements, and then verify the implementation together with the development team.

08 Explain "Why" and special Rules with Annotations

Figma Dev Mode currently supports Annotations, Measurements, and version comparisons. For special spacings, status triggers, and data rules, they can be directly pasted near the corresponding designs.

Annotations should not repeat all visible dimensions to the naked eye, but should supplement behaviors and constraints that are not obvious in the design document itself.

09 Ready for Dev may still change, but the changes must be traceable

Real projects will not be completely frozen. The key is to notify the development team after the change, record the version, and explain the scope of impact.

Figma's Compare Changes and status notifications can facilitate collaboration, but the team still needs Jira/ task flow to define who confirms the changes to avoid the situation where "the designer secretly made changes but the developers didn't see them".

10 Ready for Dev should represent "complete achievable information", not "Designers no longer modify"

A page visual finalization that lacks Empty, Error, Loading, responsiveness, and motion effect descriptions is not truly Ready. Conversely, even after the development has begun, reasonable adjustments may still be made due to real technical constraints.

Mature delivery is more like a state threshold: key rules have been confirmed, unknown items have responsible persons, and changes can be traced, rather than freezing design documents into undiscussable pictures.

11 Design QA should occur at three levels: component, page, and actual build

The component layer checks the status and Token, the page layer checks the content and responsiveness, and the real build layer checks the font rendering, browser differences, motion performance and interaction behavior.

If Q&A is only conducted within Figma, many issues that truly affect the experience will not arise until the code environment. It is still necessary for designers to participate in the front-end acceptance.

Frequently Asked Questions

When can the design draft be marked as "Ready for Dev"?

When requirements, main processes, statuses, responsiveness and components reach an implementable level and have undergone design self-checks and necessary reviews.

Do all dimensions need to be marked?

There is no need to repeatedly mark the values that the system can automatically Inspect. Focus on marking special rules, breakpoints, and behaviors.

Do designers need to conduct accessibility tests?

At least the contrast, focus, size and status that can be controlled by the design layer should be checked, and the final implementation test should be completed together with the development team.

Can the design still be modified after delivery?

Sure, but it must be managed through clear version and change notifications; silent overwriting is not allowed.

Can Figma Dev Mode solve all Handoff problems?

No. The tool can provide specifications and status, but the logic of requirements, content and communication responsibilities still need to be guaranteed by the team process.
