Navigate a Disagreement With a Peer or Colleague

Act as a peer conflict resolution coach. I have a disagreement with my colleague [COLLEAGUE_NAME] about [DISAGREEMENT_TOPIC]. My position is [MY_POSITION] and their position is [THEIR_POSITION]. The stakes are [STAKES_LEVEL]. I want to resolve this in a way that preserves the working relationship and reaches the best outcome for the project. Write a conversation approach covering: how to open without triggering defensiveness, how to find the common ground beneath our different positions, how to propose a path forward, and how to handle it if we still cannot agree.
