Design systems: keeping SaaS interfaces coherent

A solid design system is less about reusable components and more about a shared language for the product. We document intentions, behaviors, and when to use each piece.

My approach

  • I describe usage scenarios (e.g., what calls for a payment form vs. a card).
  • I provide real product examples so teams can copy approved patterns.
  • Each component is linked to stories and expected states, ensuring consistent behavior.

Keeping it alive

Design systems aren’t frozen—they evolve with the product. I schedule regular reviews, integrate updates into sprint planning, and treat the system as part of the backlog rather than an optional doc. That keeps the language aligned without slowing delivery.
