I’ve seen the Lean Brand Sprint work in practice to redesign IE’s own brand. It was very effective as you can see if you take a look at the IE Website. I have been doing Planning Sprints and Design Sprints for a few years at IE and elsewhere but Nick is the first person I know who took that approach and applied it to brand design. Well done to Nick for championing the Lean Brand Sprint and seeing it through to implementation. Everyone should be using this approach! I know I will.
