Treat the handoff as a specification
A polished Figma file is a visual reference, not a complete build specification. Developers also need to know what happens when an input is invalid, when content exceeds the design, when a user has no permissions or when an animation should stop. Missing answers become assumptions, and assumptions create rework.
Start by outlining each user task. Link the screen designs to those tasks and keep a short decision log for anything that might affect behavior.
Document components and their states
For a navigation component, define desktop hover and keyboard behavior, touch navigation, active states, submenus and what happens when the viewport is narrow. For buttons, define disabled, loading, hover, focus and success conditions. For forms, specify required fields, validation rules, inline errors and how input is preserved after a failed submission.
Use reusable components and tokens for color, spacing, typography and border radii. Developers need to know which variants are intentional so the build remains coherent across pages.
Responsive behavior deserves its own review
Do not simply shrink the desktop composition into a mobile frame. Decide when a layout stacks, when a table becomes horizontally scrollable, whether a hero illustration changes crop and how sticky controls behave with a mobile keyboard open.
Supply real-world content. A page title in German may be longer than its English version, a client name may wrap, and a project screenshot can have the wrong aspect ratio. Responsive design should accommodate these variations rather than depending on placeholder text.
Plan accessibility as product behavior
Capture heading hierarchy, meaningful alternative text, input labels, error announcements and keyboard focus. Use accessible color contrast and make interactions usable without relying on hover. Respect reduced-motion preferences and avoid transitions that obscure instructions or delay navigation.
Accessibility checks should cover implementation, not only the mockups. Schedule a review in the browser with semantic HTML, keyboard navigation and an appropriate automated audit.
Deliver assets and decision rules
Export graphics in suitable formats: SVG for interface icons and marks, appropriately sized WebP or AVIF for photographs when supported, and fallback formats where necessary. Specify whether an illustration can be cropped, how images should load and which media comes from the CMS.
Agree on typography licenses and font-loading behavior. Prefer a small number of type styles with well-defined use cases over many visually similar font sizes.
Interaction decisions that deserve documentation
A design handoff should include the first-load state, loading state, error state and success state for every important transaction. Consider a project enquiry form: does an invalid email receive inline feedback, does a failed network request preserve the entered text, does the submit button indicate progress, and is success announced accessibly? These choices shape trust more than a decorative animation.
For a portfolio, specify how a visitor changes filters, how project imagery opens, and whether an unavailable project link is clearly labelled. Make sure interactions work on devices without hover, including touchscreen laptops.
How to review implementation against the Figma system
Use a short list of meaningful checkpoints rather than trying to pixel-match every screenshot. Verify type hierarchy, layout alignment, mobile breakpoints, spacing rhythm, focus treatment, image crop and content wrapping. Compare responsive states using real article titles and lengthy client names.
Ask developers to identify where browser behavior differs from the mockup for a good reason. Sometimes a semantic form element or a native control serves users better than an exact visual imitation. Record intentional differences so reviewers do not reopen settled decisions.
A handoff checklist that reduces revisions
- Pages, components and interaction states mapped to user tasks
- Responsive layout rules for desktop, tablet and mobile
- Realistic content examples and empty/error cases
- Typography, spacing and color tokens
- Accessibility and keyboard requirements
- Animation durations and reduced-motion alternatives
- Exported icons and image specifications
- QA owners and acceptance criteria

Try a focused pilot before the main commitment
Pick a complex interface element such as a checkout form, mega menu or responsive table. Compare its resting state, focused state, error state, loading state and empty state in Figma and code. If any are unspecified, the development team is being asked to invent product behavior.
Information to include in the handover
Maintain a component inventory, supported breakpoints, font licenses, spacing tokens, design source file, interaction videos where useful, long-label behavior and named reviewers. Identify which illustrated effects are decorative and what users should experience with reduced motion.
How to review the result
Review the implemented component with keyboard and touch input as well as a screenshot comparison. A visually exact implementation can still fail if opening a dropdown moves focus unpredictably or blocks a screen reader.
A useful acceptance meeting should include the future content or operations owner, not only the person who commissioned the design. Ask participants to demonstrate the normal task and an awkward edge case, then record fixes, responsible owners and unresolved risks. Store those decisions somewhere the next developer or editor can actually find them.
Before publishing, confirm current technology versions and any local regulatory assumptions with authoritative sources. These planning exercises are suggestions, not evidence of a completed AppsBrain client project.
A practical release sign-off
Before anyone calls the change complete, record the current state and choose at least three real tasks that matter to customers or editors. Assign an owner for reviewing each task and keep private data out of screenshots shared for review. Test the expected successful path, an incorrect or missing-input path, and the behavior when a dependency such as email or a third-party provider fails. Retain the earlier working version until the new one is accepted, with a documented procedure for reversing the release. After launch, schedule a short review of feedback and support questions; unexpected operational friction is often visible there before it appears in an analytics dashboard.
