Escalate to a shared north star or a senior stakeholder who can weigh the tradeoff, quantify the impact on both sides, and reach a decision with explicit data rather than opinion.

Example: the ads team wants more ad inventory (hurts user experience metric owned by the product team). Resolution: quantify the revenue gain vs retention cost, check which direction the company-level north star moves, and escalate if the local tradeoff is ambiguous. Document the decision and its reasoning so it does not need to be relitigated. Preventing recurring disputes requires clearer metric ownership and cross-team OKRs.
