I once had to tell a new hire that 3 days of work were based on a decision we’d reversed 6 months earlier. The documentation still said the old version. Nobody had gone back to fix it.
That’s the problem with most design process documentation. Teams treat it like a deliverable. Write it once, ship it, move on to the next thing. Nobody revisits it until it’s wrong.
It helps to be clear about what kind of documentation this is. Design system documentation describes the what: your components, tokens, and patterns. It tells someone how to build the right button. Design process documentation describes the how and why: how decisions get made, who owns them, why one tradeoff was chosen over another. It’s the difference between a component library and the reasoning that got you there. Most teams invest heavily in the first and treat the second as an afterthought.
But if you treat it like a product instead, the whole approach changes.
A product has users. So does your documentation, whether you’re thinking about them or not. New hires trying to get oriented. Adjacent teams trying to understand a decision. Future you, 6 months from now, trying to remember why you made a call in the first place. If you don’t know who’s actually reading it, you can’t know what it needs to say.
A product gets maintained. Nobody ships a feature and walks away forever. Your process docs need the same discipline. When a decision changes, someone owns updating the doc. Set a cadence for this, quarterly reviews work well for most teams, and put it on a calendar instead of hoping someone remembers.
A product has a feedback loop. Ask the people using your documentation what’s missing, what’s outdated, what confused them the first time they opened it. You’ll find gaps you didn’t know were there.
A product earns its place. If nobody’s reading your documentation, that’s useful information. Maybe it’s buried in the wrong tool. Maybe it’s written for an audience that doesn’t exist. Or maybe the process just doesn’t need a doc yet, and that’s fine too.
The best design orgs I’ve worked with don’t have more documentation than everyone else. They have documentation people actually trust, because someone treats it with the same rigor they’d treat any product they’re responsible for.
What’s one piece of documentation on your team that’s overdue for a refresh?
