For me:

- the goal

- 5 dysfunctions of a team

- the first 90 days

A friend swears by:

- atomic habits

- seven habits of highly effective people

(Slightly different genre but quite close)

Oooooh! I forgot about Atomic Habits. It's not only one of the best "business books" I've ever read. It's the single best "self-help" book I've ever read.

I disagree on "Seven Habits" as its model of "effectiveness" is only applicable to (for lack of a better term) extroverted vocations.
