What This Proposal Covers

1

The Challenge

Diagnose the client's design debt: inconsistent UI patterns, duplicated components, slow feature development, and poor accessibility across product surfaces.

2

The Vision

Describe a unified design system with documented components, design tokens, and usage guidelines that every team can adopt immediately.

3

Our Approach

Outline your design system process: component audit, token architecture, Figma library creation, React component development, documentation, and rollout plan.

4

Why Us

Share design system projects with adoption metrics: development speed improvements, reduced design inconsistencies, and faster onboarding for new team members.

5

Investment

Price the design system in layers: foundation (tokens, typography, color), core components, complex patterns, documentation site, and team training.

6

Next Steps

Describe the rollout plan: pilot team adoption, feedback collection, iteration cycle, and organization-wide launch with training sessions.

Key Features

  • Design token architecture and theming
  • Accessible React component library
  • Figma library with developer handoff specs
  • Living documentation site with usage examples

Frequently Asked Questions

How do I justify the cost of a design system?
Calculate time wasted rebuilding components across teams. A design system typically saves 30-50% of UI development time after the first quarter of adoption. Frame it as infrastructure investment.
Should a design system proposal include Figma and code?
Yes. A design system needs both a Figma library for designers and a coded component library for developers. Without both, adoption will stall on one side.
How long does it take to build a design system?
A foundational design system takes 8-16 weeks for tokens, 15-20 core components, and documentation. Plan for ongoing iteration as teams adopt it and request new patterns.
