Thanks for sharing this Katie. Really brilliant example of building to learn. One thing I am particularly inspired by is the safety net you put in place while testing it out. Instead of just observing people using the prototype way finding (and potentially getting lost in an emergency situation), you participated. Not only is that more ethical, it probably also taught you and the team more about how it worked (or didn’t). Inspiring! There’s got to be a forest/trees pun in here..
