Every time a self-predicting program is run, the product deviates from the design, and often no one knows until it is too late.
A smooth handover means programming without guessing any important details: distance, color, behavior, screen state, or content. A complete handover includes clear specifications, ready-to-use assets, dynamic behavior descriptions, and final content. If any part is missing, programming will fill in the gaps in their own way, not the designer's.
Delivering design is a transfer of responsibility, not the end point of the design process. If this step is unclear, programmers will fill in every ambiguous spot based on their judgment, and the result often does not match the original design. Programmers are not wrong; they simply do not have enough information to do it right.
Design and programming are two professions that think in two different languages. Design is visual, feeling proportions, and judging space. Programming requires numbers: pixels, color codes, line heights, font weights. A beautiful Figma file cannot express those numbers on its own. Looking at a static file, programmers can hardly know the exact pixel measurements of each element, so they have to guess.
Modern handover is not about piling on redline documents (annotating specifications on design files) and static specs (detailed technical description tables). It is about creating a living system where design and programming speak the same language through tokens (shared design variables), conventions, and common tools.
Sinh Vũ considers a deliverable complete when the programming does not need to ask about any of the following:
Delivering the interface for the client's technical team to program: Must include complete specs and tokens as Sinh Vũ does not oversee the building process. There is a higher risk if the technical team is not familiar with reading Figma or lacks established token conventions.
Sinh Vũ offers complete design and programming: Internal delivery is lighter on procedures. However, a final content version and sufficient screen states are still needed to build correctly from the start.
Collaborating with the client's existing technical team: It is necessary to agree on tokens and naming conventions with their current system before the official handover. This is a step many parties overlook and pay for later.
Sinh Vũ understands "smooth" in this sense: both parties read the same language, and neither side has to guess what is important. Delivery does not end at the moment of handing over the file; it ends when the programming is complete and the product matches the design at a level you can accept.
Therefore, in every scope, even when only designing the interface for the client’s team to program, Sinh Vũ provides operational guidelines so that the client’s team understands and can run it themselves. It’s not just about receiving a bunch of files and guessing how to use them.
Modern handover is about creating a living system where design and programming speak the same language through tokens, conventions, and common tools, rather than just adding static technical documentation.

Figma Inspect helps developers read the properties of each element, but it cannot replace a dynamic behavior description, a list of screen states, or the final content. If the design does not prepare enough screen states, Inspect has nothing to read. It is a supporting tool, but cannot fill in the gaps on its own.
It is not necessary to create a lengthy document. What matters is having all the components: specifications, assets, status, behavior, content, and a point of contact for any questions. The format can be annotations directly in Figma, a note page attached, or a live walkthrough, depending on the project's scale.
You need to sit down and agree before handover: how the design tokens map to the programming team's tokens. For example, which primary color in Figma corresponds to which variable in their codebase. This step takes little time but prevents many discrepancies later.
