If you refer to someone's tacit agreement or approval, you mean they are agreeing to something or approving it without actually saying so, often because they are unwilling to admit to doing so.

Cleanup over sign-off As discussed in Sid's interview on iteration, waiting for approval can slow things down. We can prevent this with automation (e.g. tests of database migration performance) or clean-up after the fact (refactor a Pajamas if something was added that isn't coherent), but we try to ensure people don't need to wait for signoff.

Make two-way door decisions Most decisions are easy to reverse, have the directly responsible individual make them without approval. As Jeff Bezos describes only when you can't reverse them should there be a more thorough discussion.

the third level of education requires profound honesty. It asks that you become a person who can look at life objectively with honesty and consistency. You are not trying to be a wonderful person now; you are not trying to be a villain, either. You're not even trying "to be." You are freed from the attempt to be someone. This is the greatest freedom you can experience in life. In a way, the quest to be someone has to be relinquished before you can be someone. Knowledge does not require that you become exemplary according to your standards. You cannot say, "I am going to use Knowledge to get more of this or less of that," because Knowledge is the Master in your life. It is moving you. You have set sails, and God is now blowing you across the world.

You must stop valuing the inputs which bolster the ego and satisfy it. I mean by that, the actions that get approval. You must at this point value the marvelous fact that you are, at this instant, connecting with me from That of you which is Fourth-dimensional. It is a concrete demonstration of your Sanity—your presence of Mind—and therefore an illuminated experience of your Being, with no distortion present.
