A generic cold-reading statement that applies to basically anyone in any organization:

"I mean I'm optimistic the official plan will work, but... there sure are a lot of challenges!"

A statement that is safe, and also always true, and somewhat subversive.

It allows the other person to glom on the additional challenges they see too.

When used in a private, candid environment, it's a magnet for disconfirming evidence, giving others permission to point out challenges they see.
