Set practical rules for proposing, reviewing, documenting, and releasing reusable website components.

A component library can become a second backlog when nobody knows whether to reuse, adapt, or create. A short contribution guide gives an outsourced design team a route from a page need to an approved reusable component without quietly multiplying variants.

Define the decision before the file format

Start with three choices: reuse an existing component, extend an approved variant, or propose a new pattern. Name the client-side person who makes that call. Give the team examples of changes that belong in page composition rather than in the shared library.

Require a useful proposal

  • Link the page and user need that exposed the gap.
  • Show the closest existing component and why it falls short.
  • Include default, hover, focus, error, empty, and loading states where relevant.
  • Record content limits, responsive behavior, and accessibility notes.
  • Identify the designer, developer, reviewer, and release owner.
  • Review with real content

    Test the proposed component with short and long headings, missing optional fields, narrow screens, keyboard input, and realistic image crops. A polished ideal-state mockup does not prove the pattern can survive daily publishing.

    Close the loop after release

    Add the accepted pattern to the client-owned library, document its intended use, and link the implemented example. Retire superseded variants deliberately. The vendor may prepare the evidence, but the client should retain naming and governance authority.

    Frequently asked questions

    Does every page variation need a component?

    No. Prefer composition when the difference is page-specific and unlikely to repeat.

    Who approves a new shared pattern?

    Assign one client-side system owner and a named backup so approvals do not disappear into group feedback.
