How do you handle disagreements within a team?

Situation: Disagreements often stem from misaligned success criteria or incomplete information. Task: Turn subjective debate into objective decision-making. Action: I restate each position and surface underlying goals. I propose measurable criteria (latency, cost, maintainability) and gather evidence—benchmarks, POCs, incident data. For technical choices, I suggest a time-boxed spike or A/B pilot. I use RACI to clarify who has final say; if consensus isn't possible, we escalate with a recommendation memo, not just opinions. I avoid ad hominem; I document the decision and rationale in an ADR so future teams understand the 'why.' Result: Disagreements resolve in days, not weeks. The team trusts the process and accepts outcomes even when they didn't win the argument.
