16:56min You’ve taken your temperature, and you realise that you’re not happy. You’re frustrated with how things are going. Let’s make a change. Let’s do what I learned from Jim Womack and people at the Lean Enterprise Institute. Let’s do an experiment. Let’s try something different. If you just keep doing the same things that you’ve done. If you’re on a one year job or a ten-year job, it doesn’t matter. If you maintain the same inputs and outputs and processes, you’re going to be in the same state of chaos all the way until the end. So, you’ve got to what’s called the safe to fail experiment.
