How do I push back on a colleague's idea without causing offense?

Question

Accepted Answer

Disagree with the reasoning rather than the person, and give the specific thing that changed your mind. English speakers read "I don't think that's right" as an attack far less than they read a vague, unexplained doubt, because the vague version leaves the listener guessing at the real objection. Name the constraint, then invite them to solve it with you.

I see it differently, because — The "because" is not optional. Without it this becomes a statement of position with nothing to discuss. Example: I see it differently, because the same change broke the importer last quarter.

What am I missing here? — Genuinely useful when you may be wrong, and it gives the other person a route to explain rather than defend. Do not use it when you are certain; it reads as sarcasm. Example: That would double the query cost as I read it — what am I missing here?

I'd want to be sure that — Raises a condition rather than an objection, which works well upwards. It leaves the decision with them while putting the risk on record. Example: I'd want to be sure that support has capacity before we bring the date forward.

Do not use the questioning forms when you have already been overruled and the decision is final. Continuing to ask "what am I missing?" after a call has been made reads as relitigating rather than clarifying. At that point say what you will do — and, if you think the risk is real, put it in writing once, plainly, and move on.
