My colleague and I keep reopening decisions we already made. How do we stop?
Your colleague needs the plan written down;
you’re happy to adjust as you go.
So when you revisit a call, they hear “the plan is gone”, and you hear “they won’t budge”.
You both say things straight,
so use it: end each decision with one written line, what, who and when you’ll look at it again, and only reopen it on that date.
