Apenwarr on Kanban

If your job is to work on a phase and there are no holes left for you to fill, then you literally have to stop work, or (if you’re flexible), go help with one of the downstream phases. And we enforce that by just not having enough physical space to paste your index cards. It’s kinda neat, as a mental trick, because the most primordial parts of your brain understand the idea that physical things take physical space and there’s no physical space left to put them in.⊕ (Pennarun 2017)
