Resolve a team conflict decisively

Tell me about a time you resolved a significant conflict within a team under time pressure. Include: 1) the root causes (interests, incentives, communication, resources) and evidence you gathered; 2) the options you considered and why you chose one; 3) how you secured buy-in from disagreeing parties; 4) how you enforced decisions and protected delivery timelines; 5) the measurable outcome and post-mortem learnings; 6) what you would do differently if the conflict involved a power imbalance or a remote team.
