What is WIP Limit?
A WIP (Work in Progress) limit is a cap on how many tasks can be in a particular workflow stage at the same time. The idea is simple: by limiting how much you're actively working on, you finish things faster and reduce context switching.
Understanding WIP Limit
WIP limits come from lean manufacturing, where having too much inventory in progress creates waste, delays, and chaos on the factory floor. The same principle applies to knowledge work. When you have 15 tasks 'in progress,' you're not actually making progress on any of them — you're just context switching between half-finished work.
Research on multitasking consistently shows that humans are terrible at it. Every time you switch between tasks, there's a cognitive switching cost — it takes time to re-load the context of what you were doing. With a WIP limit of, say, 3 tasks, you force yourself to finish something before starting something new. The result: fewer open loops, less mental load, and faster completion.
You don't need a formal WIP limit rule to benefit from this concept. Even being aware that 'fewer active tasks equals faster progress' can change how you plan your day. Instead of starting five things and finishing none, start one or two, knock them out, and pull the next task forward.
How skift Uses WIP Limit
skift's Kanban board naturally encourages WIP awareness. When your 'In Progress' column starts getting crowded, it's visually obvious — you can see you've taken on too much at once. The board layout nudges you to finish active tasks before dragging new ones in, bringing the WIP limit philosophy to your daily planning without rigid rules.
