Delivering a pile of files and leaving is the surest way for the design system to die within six months.
The team can operate independently without a handover session, but thanks to a system designed to function autonomously from the start. Three things must accompany the system: living documents that can be used directly, a clear change approval process, and a person or group responsible for maintaining the system. Missing any of the three will cause the system to dilute over time, no matter how well it was initially built.
The value of a design system only becomes apparent when product teams truly use it to develop features, not when the library is launched. In other words, successful delivery is not measured by a grand launch event, but by a much simpler question: three months later, can your team add new components on their own, can they look up documentation independently, can they approve changes without assistance?
Most failed handovers are not due to a poorly built system. They fail because the handover only transfers files, not operational capabilities. For the team to truly stand on its own, three factors must accompany the system from the beginning, not added later.
If you’re not sure what type the team belongs to, ask directly: "Has anyone on the team ever added a new component to a standard library?" If the answer is no, consider pairing them up.
One often-overlooked issue during handover is that designs in Figma and the actual code can drift apart. The development team looks at the Figma file, guesses the parameters, and gradually the two sides go in different directions. Figma Code Connect serves as a bridge so that when developers look at a component in Figma, they immediately see the corresponding code they need to use, without guessing. This significantly reduces the need for back-and-forth questions between design and technical teams.
Maintaining the system is a continuous task. Someone must treat the system as a living product and care for it regularly; otherwise, the system will gradually dilute over time.

In all three phases of work, Sinh Vũ aims for a single goal: for the client team to be self-sufficient after Sinh Vũ withdraws. The development phase has Storybook and Figma Code Connect to keep documentation alive alongside the code. The implementation phase includes an RFC management process and a set of metrics to track actual application levels. After handover, Sinh Vũ stays on for the first three months to help the team get accustomed to adding components, proposing changes, and self-approving according to the process, before truly becoming fully independent.
What Sinh Vũ observes most is that teams fail not due to a lack of talent, but because they are not provided with sufficient tools and processes to make decisions. A good design system, delivered correctly, will reduce dependence on any individual, even the one who built it.

There is no absolute number, as it depends on the team's experience. For a team taking over a design system for the first time, Sinh Vũ typically conducts about 3 to 5 direct pairing sessions, focusing on how to properly add new components and how to use Storybook daily. More important than the number of sessions is that the team must be able to make at least one real change before Sinh Vũ steps back.
Storybook is currently the most popular tool because it allows developers to view, test, and retrieve code directly in the browser without needing to ask the designer. If the team already has other documentation infrastructure running well, it is more important to ensure that this documentation is continuously updated and that the team truly references it, not just leaving it aside.
RFC (Request for Comments, meaning change proposal) is a process that allows anyone on the team to propose additions or modifications to a component without altering the source standard. It doesn't need to be complicated. A simple proposal template along with an approval step from the system owner is enough to prevent everyone from making changes in different ways, leading to a broken system without anyone knowing the cause.
