We had to fight some myths…!


“Kanban is decaf Scrum”!


“Kanban opens Pandora’s box”!


“WIP limits are impossible to fulfill here”!


“When something gets blocked, just start with something else”!


Here’s how we did it!


Here’s how we did it!


Start mapping your value stream!


Add columns accordingly!Selected Backlog Code Test Done! Design


Categorize demand!Selected Backlog Code Test Done! Design


Be sure there’s a prioritizing mechanism and a single entry point!

¿Your prediction?

Uuuh… Well, on average we make something like 75 scrum points per sprint. Guess we can commit on that as long as you keep the uncertainty level safe…

That means somewhere below 25 buffer points
