Conclusion: Miss

Boeing’s comms efforts were hobbled from the outset by a lack of information. One can’t help but wonder if Boeing couldn’t have voluntarily grounded the plane before Trump’s executive order.


1. Listen to your regulators. In Boeing’s case, this is easier said than done. But if DC fails to give comprehensive guidance, meet the issue with urgency and empathy.

2. Listen to the consumer, even if they’re not yours. When fliers began to worry, Boeing should’ve released a consumer-centric message.
