Handoff designs to developers

Prepare the design package for handoff of the new onboarding flow to Rahul and the frontend team. Include component usage notes, interaction states, a mapping of which components are custom versus library, and a prioritized list of items that will need engineering decisions. Ask Rahul to sign off on the implementation plan by Tuesday noon.

Before I hand off onboarding, make it easy for developers to implement: surface the three components that require custom work up front, make the variant rules and props findable, and flag any animations or micro-interactions that will need engineering sign-off because they rely on timing or nonstandard behaviors.

I just completed the handoff and Rahul's team asked which component controls the onboarding modal behavior. They need to know if it is a library component to reuse or a custom one to reimplement. I do not know whether the behavior was prototyped inside a nested variant or a separate overlay. Should I inspect the component hierarchy, send a quick recorded walkthrough, or mark the component as custom and provide the implementation details? What will avoid blocked work overnight?

Over multiple handoffs I keep getting follow-up questions about which components are library-owned and which are one-off, causing rework and missed deadlines. I want a practice that clarifies ownership at handoff and reduces back-and-forth. What explicit ownership note, file structure convention, and quick verification step should I adopt so developers know what to reuse and what to rebuild?
