Over time the original reason for the way you are working now will have changed. The initial problem you had might be solved, or the context might have changed sufficiently for current policies or solutions to become less effective.
This presentation will go into closing the feedback loop on your initial design decisions and policies and get the focus back on why Kanban was adopted in the first place. It revisits the first Kanban principle "Start with what you do now".
In this talk will be the some experiences from the field on how to keep the focus on why certain policies where implemented in the first place and validate if they are still an effective way of solving problems. Both from my own experience as well as from other people.
