What I was taught in school and in the early days of my career:
analyze – plan – budget – convene – write fancy document – present – get approvals – get buy-in – hold some more meetings – adjust budget – communicate and roll out the plan.
How it really works:
sense – dare – dream – share your dream with a few people you trust – get the resources – ask for permission later
The challenge is, you can’t get good at the second approach if you’re spending all your time working on the first one.
