Validated Learning

In The Lean Startup the concept of validated learning is the process of determining emperically that a team has discovered valuable truths of the startups present or future business prospects. You only have learned when you measured that your customers exposed different behavior

Combining this concept of validated learning in a Kanban@kanban board can be a great way to push a development team to design experiments that will enable them to learn if they make the right decisions in their product development. If the validation fails, the feature is removed from the product.
