Laws of Showrunning (2016) [pdf]
There are some well-worn ideas here expressed in I think fairly elegant terms:> To successfully define a path to success, you don't even have to 
know the exact hill to take. The grinding race that is television 
often means that you may not always know the next goal; but even 
if you articulate your order as "Help me figure out the next hill 
to take," or "Let me know what our resources are so that I can 
make an educated decision about where to attack next," that alone 
constitutes a directive with a defined outcome.
