What is a Kanban?

“A Card (or traditionally, a Kanban), is a symbolic token representing a unit of effort, either to be completed or in the process of being completed.”

Future Past Present

Why Lord? Why?

Why Limit Your WIP?

WIP (work-in-progress) is the proverbial “balls in the air you are juggling.”

!e more balls in the air, the harder it is to

Challenges & Observations

Walk the Gemba > Walking up the inference ladder Make the board work for you & your team •  Start with your existing process •  !ere is no “One True Board!”

Keeping the value stream filled Pull is a mindset! Beware of “Infinite WIP” Recognize the true cost of context switching
