I think the flowchart is of value more as awareness of all the elements that
could be involved in a successful launch.
You don't actually have to get bogged down at each step like an agency doing 3rd party work might. Nevertheless I personally have a two step plan after learning from my
"failures":
1. build a great product
2. build as real of a marketing plan as possible especially for week one of your launch
"Great" in this case is about my gut instinct; I think we all know at some level when we've made something just average, good or great.
