Visualize the work
Cards on a board, columns for workflow states (Backlog → In Progress → Blocked → Done is the most common starter setup). You can't manage flow you can't see — the board IS the process visible.
Limit work-in-progress (WIP)
The defining practice. Each column has a cap. New work enters only when capacity opens up. WIP limits force you to finish before you start — a system with too much WIP gets slower, not faster, because each item competes for attention.
Stop starting; start finishing.
— Donald Reinertsen, paraphrased
Manage flow
Track cycle time (how long from In Progress → Done) and look for variance. A long cycle time means work is getting stuck somewhere. A high-variance cycle time means the system is unpredictable — your forecasts won't hold.
