Notes
- Pull principle is a mechanism for controlling product development workflow.
- The upstream process isn't allowed to take more work unless it has capacity.
- A team only picks up the next piece of work from the previous stage when they have available capacity—they've completed other work, and their WIP won't exceed.
- The opposite is the push principle, in which team members finish their work and push along into the next processing step, ignoring capacity and WIP.
