I really appreciate this post. A recurring thought while reading this steals from Horace Dediu's "what job was X hired to do" idea. The high level, obvious word to insert for X would be company name. Along with the "What, precisely, are you trying to do?" question mentioned, this additional question helps to reveal core themes or purpose, especially when inserting lower level examples for X, such as division, team, strategy, product or service, contract, etc.

This question is simple enough that the response often seems obvious or safely assumed. But, it serves as a filter, exposing critical information or reminders.
