项目经理和产品经理在项目开发过程中可能会有不同的观点和利益冲突，但他们通常是合作关系，而不是打架关系。他们的职责和角色不同，项目经理负责项目的整体管理和执行，产品经理负责产品的规划和设计。他们需要相互协作，共同推动项目的成功。

当项目经理和产品经理产生分歧时，他们应该通过沟通和协商来解决问题，而不是采取暴力冲突的方式。他们可以通过开会讨论、提出建议、寻求共识等方式来解决分歧，以达到项目目标和产品需求的平衡。

如果项目经理和产品经理之间存在严重的冲突无法解决，可以寻求上级领导或相关部门的介入，以寻求更好的解决方案。最重要的是，项目经理和产品经理应该保持专业和尊重，以确保项目的顺利进行。

It is important for project managers and product managers to have effective communication and collaboration skills to avoid conflicts and work together towards the success of the project. Here are some strategies they can use to resolve disagreements:

1. Active listening: Both project managers and product managers should actively listen to each other's perspectives and concerns. This helps in understanding each other's viewpoints and finding common ground.

2. Clear communication: They should clearly communicate their expectations, goals, and requirements to each other. This helps in avoiding misunderstandings and ensures that everyone is on the same page.

3. Compromise and negotiation: Both parties should be open to compromise and negotiate to find a solution that meets the project's objectives and satisfies the product requirements. This may involve finding a middle ground or prioritizing certain features or tasks.

4. Seek input from stakeholders: In case of disagreements, involving relevant stakeholders can provide additional insights and perspectives. This can help in making informed decisions and finding a resolution that aligns with the project's goals.

5. Escalate if necessary: If the conflict persists and cannot be resolved through discussions, it may be necessary to escalate the issue to higher management or seek mediation from a neutral third party. This can help in finding a fair and unbiased resolution.

Remember, the ultimate goal is to work together as a team and deliver a successful project. By maintaining open communication, mutual respect, and a focus on the project's objectives, project managers and product managers can overcome conflicts and achieve their goals.
