Deliver as 'One Arm'

Understand the connections and complexities beyond your function. Collaboration isn't always consensus.

Back to the universal principles

Calibration

Under, just right, over.

Situation	Under	Just Right	Over
A decision that touches another team	Decides inside the function and tells the other team after it has shipped.	Learns how the decision lands on them, then makes the call without waiting for every vote.	Will not decide until every adjacent team has agreed, and the week is gone.
A dependency you do not own	Treats the other team's queue as none of your business until you are blocked.	Says what you need, what they are carrying, and a smaller slice that unblocks both sides.	Takes over their work so you do not have to depend on them.
A meeting of only your function	Solves a cross-team problem with the people who already share your view.	Brings in the person who will live with the result, hears them, and still leaves with a decision.	Invites so many functions that the meeting cannot decide anything.
Collaboration versus consensus	Equates disagreement with a failed collaboration and forces a watered-down middle.	Understands the other view, states the disagreement, and decides.	Calls a solo decision collaboration because you sent a note afterward.
Connections you have not mapped	Optimizes the function and is surprised by what breaks downstream.	Draws the two or three connections that matter for this decision and checks them.	Maps the whole company before a local call that only one other team feels.
Backing a cross-team call	Agrees in the meeting and undoes it back inside the function.	Carries the decision back, including the part your own team did not prefer.	Polices the other team all week to prove you are collaborating.
