Focus on outcomes over outputs
Communicating on engineering activity is hard, especially with a non-technical audience. It is tempting, for a lack of better option, to fall into the trap of sharing output metrics which say little about success (e.g., number of changes, time to review).
Echoes reports are devoid of engineering jargon and focus on the "why" over the "how". This makes them appropriate to use with your boss, as well as your CEO, CFO, or partners in other functions.
