Have you heard the saying "Disagree and commit"?
This is a fundamental tenant of Silicon Valley culture.
It's an easy catchphrase that means that even if some people disagree, once the decision is made, everyone gets to work to make it work!
However, I've noticed that some companies have a culture of "Agreeing but failing to commit."
There are lots of soft "yes" and soft "maybe" that never translate to a change in vocabulary and execution in the org.
Make decisions. Make changes. Move on.
