is that baked into your covering off process?

here are some more phrases i've noticed being used around my office but which don't really mean anything.

cover off on v. cover. usage: "did we cover off on everything on our agenda? i don't want to skip anything." real words/phrases that could be used instead: "did we cover everything on our agenda? i don't want to skip anything."

buttoned up adj. calm under pressure. usage: "joe has so many projects going on but you'd never know because he is so buttoned up and everything gets done on time." real words/phrases that could be used instead: "joe has so many projects going on and never misses a beat; everything gets done on time."

baked in adj. included. usage: "don't worry about doing QA; that's baked into our processes here." real words/phrases that could be used instead: "don't worry about doing QA; that's included in our processes here."
