The GM Nod

From the 2014 Valukas Report, the independent investigation (led by former federal prosecutor Anton Valukas) into General Motors’ decade-long failure to recall cars with a fatal ignition-switch defect. GM CEO Mary Barra told investigators about a habit she had watched inside her own company, one known there as the GM nod.

In the meeting, everyone speaks, and the word is yes; the plan dies the moment the room clears, because agreeing was the whole commitment and nobody walked out owning it. The report pairs the nod with the GM salute, arms crossed and fingers pointing outward to signal that the job belongs to someone else. Between them they describe a culture where a decision can be approved by everyone and owned by no one. And the nod was of a piece with a wider silence the same report documents: a reluctance to raise problems up the chain, and engineers trained to keep words like defect and dangerous off the page. Nodding in the room was how you avoided disagreeing; leaving was how you avoided owning it.
