Design systems have become one of the most talked about deliverables in the industry over the last several years. Every agency pitches them, every in-house team wants one, and a significant number of them end up as beautiful, comprehensive, completely unused documents sitting in a shared drive somewhere. The problem is not that design systems are a bad idea — they are an extraordinarily good idea. The problem is that most of them are built the wrong way, for the wrong reasons, with the wrong priorities. A design system that gets used is not the most comprehensive one. It is the most useful one. And useful and comprehensive are not the same thing.
Start With What Actually Gets Built
The most common mistake teams make when building a design system is starting with everything rather than starting with what matters most right now. They spend months documenting every possible component, every edge case, every variant — and by the time the system is ready to use, the product has already moved on and half the documentation is already out of date. A better approach is to start with the components that are actually being built today. What are the five or six elements that appear on every page of your product? Start there. Build those components thoroughly, document them clearly, get them into the hands of the people who will use them, and iterate from there. A small system that gets used is infinitely more valuable than a comprehensive one that does not.
Documentation Is The Product
One of the most underappreciated truths about design systems is that the documentation is as important as the components themselves. A beautifully built component with no documentation is nearly useless to anyone who did not build it. They do not know when to use it, how to use it, what variants are available, what the rules are around spacing and colour, or what happens in edge cases. Good documentation answers all of these questions before they are asked. It shows the component in context, explains the decisions behind it and gives clear guidance on when it should and should not be used. Writing this documentation takes time — often more time than building the component itself. But it is what transforms a collection of components into a system that a whole team can use confidently and independently.
Governance Is What Makes It Last
Even the best designed and documented system will decay without governance. Governance is the set of processes and responsibilities that determine how the system evolves over time — who can propose changes, how those changes are reviewed and approved, how updates are communicated to the people using the system and how conflicts between the system and individual product needs are resolved. Without governance, design systems drift. Individual teams start making local exceptions that never make it back into the system. Components get duplicated and modified. The single source of truth becomes three sources of truth and then twelve. A lightweight governance model — even just a clear owner, a regular review cadence and a simple process for proposing changes — is enough to prevent most of this decay. It does not need to be complicated. It needs to be consistent.
A design system is not a project with an end date. It is a product that needs to be maintained, evolved and governed with the same care and intention as any other product your team ships. The studios and teams that understand this build systems that genuinely improve how they work over time. The ones that treat it as a one-time deliverable end up starting from scratch every eighteen months. At Glyph Co. we build design systems for clients as living tools — with clear documentation, sensible governance and a genuine commitment to making them useful rather than just comprehensive. That is the only kind of design system worth building.
