🏛️ RTT Facilities — Design System Governance
Clarity Before Aesthetics
DESIGN IS A GOVERNANCE SURFACE#
Every visual decision communicates meaning.
Every component shapes understanding.
Every inconsistency erodes trust.
Design is not decoration —
it is infrastructure for decision‑making.
WHAT THIS DESIGN SYSTEM EXISTS TO DO#
The RTT Facilities design system exists to:
- Preserve semantic clarity
- Support infrastructure governance
- Scale across domains and audiences
- Remain coherent over time
If a design choice does not support these goals, it does not belong.
CORE PRINCIPLES#
🧠 Semantic First#
Meaning precedes appearance.
Names, structure, and intent matter more than style.
🏛️ Governance Aligned#
Design must clarify decisions, risk, and accountability.
👥 Audience Aware#
Complexity is gated.
Executives, operators, and the public see what they need — no more, no less.
🔍 Explainable#
Every visual should be explainable in plain language.
🧱 Durable#
Design must survive redesigns, tools, and contributors.
COMPONENTS ARE CONTRACTS#
Every component must:
- Represent a Facilities concept
- Map to the Global Index Schema
- Follow the Naming Convention
- Pass the Creation Checklist
- Be reviewed before inclusion
Undocumented or ad‑hoc components are prohibited.
STRUCTURE IS MEANING#
- Folder structure encodes governance concepts
- Naming encodes function and ownership
- Variants gate audience and context
- State is never hidden in style
If meaning is unclear, structure has failed.
STEWARDSHIP MODEL#
A Design System Steward is responsible for:
- Reviewing component proposals
- Enforcing naming and structure
- Preventing duplication and drift
- Approving canonical changes
- Preserving documentation integrity
Stewardship is curation, not gatekeeping.
CHANGE IS A GOVERNANCE EVENT#
- Canonical changes require rationale
- Breaking changes are documented
- Exceptions are explicit and time‑bound
- Silent drift is prohibited
Design evolves — but never invisibly.
ACCESSIBILITY IS NON‑NEGOTIABLE#
Accessibility failures are governance failures.
All design must:
- Meet contrast standards
- Avoid color‑only signaling
- Support assistive technologies
- Minimize non‑essential motion
WHAT THIS SYSTEM IS NOT#
- Not a style guide
- Not a branding exercise
- Not a UI trend collection
- Not a playground for experimentation
Exploration happens outside the canonical system.
THE TEST#
Before shipping any design artifact, ask:
Does this make infrastructure risk, readiness, or governance clearer?
If the answer is no — revise.
CANONICAL STATUS#
This poster reflects binding design‑system governance.
All RTT Facilities design work must align with it.
