Today we learned about Nodstrom Innovation Lab, a lean startup within the Fortune 500 company Nodstrom (fashion & apparel retail). 

In this video, you can see how the Nodstrom Innovation Lab team performs a so-called “Flash Build”; similar to a flash mob but in this case they arrive to a retail without prior notice, deploy their material and aim to build a working app within 5 days, constantly iterating with the customers.
