Meanwhile, managers are busy... managing 🙄.

What objectives should take priority?
What projects will yield more results?

These questions are hard; there's a lot of guessing involved. Developers are not helping if everything is answered with a: "it depends", "it's complicated", "we will see".

In order to do their job, managers need to abstract themselves from the complexity of execution. They need their GPS.

Specially when they are deciding over many different things at once.
