This guidance describes how to quickly assign tasks in a project without getting bogged down in details.
At the start of a project, there are usually discussions about who is going to do what by when. Those discussions turn to what are the tasks and in what order do we do them and what are their exact order. This is ineffective. It's better to start with some rough estimates, and then refine details once you start.
[Ed Note: This guidance references principles in our earlier guidance, "Horstman's Law of Project Management." It's not necessary to read/listen to it, but we encourage the reader to do so when time permits. -H]
