I don’t agree with everything on this list of how to send progress updates, but these two points are especially important and worth remembering:

Acknowledge changes explicitly. If you said a the last time and b this time, and b conflicts with a, you need to explain the inconsistency. People perceive acknowledged inconsistencies as cost of doing business, but unacknowledged inconsistencies as broken promises.

I name this section “challenges and requests” in my updates, but the underlying principle is the same:

Add a dedicated section for worries and failures. Be honest, have good plans, and don’t panic. People are drawn to conscientiousness and vulnerability but repelled from haplessness and histrionics.
