So how can you tell the difference between an Ice Cream Glove and a Snuggie? You can’t. Only your customers can. There is literally no exercise at the whiteboard you can use to find this out ahead of time. A lot of startups - and a lot of technologists - make this mistake. I know I have. We're so used to attacking problems on the whiteboard, we often forget about the one of the biggest problems of all: when to turn off the computer and shut down the whiteboard. Can lead to very expensive mistakes.
