Working with Cross-Functional Partners

Engineers Speak One Language; Everyone Else Speaks Differently (工程师说一种话；其他人说另一种)

The engineer who only knows how to talk to other engineers caps out at mid-level. Senior+ work requires fluently translating between engineering, product, design, data, sales, support, and leadership. Each function has its own vocabulary, priorities, and unwritten rules.

只会和工程师说话的工程师卡在中级。资深以上的工作需要在工程、产品、设计、数据、销售、客服、领导层之间流畅翻译。每个职能有自己的词汇、优先级、潜规则。

The principle 原则: Speak in their metric, not yours. Sales cares about deals; PMs care about user value; engineers care about systems. Translate.

用对方的指标说话，不是你的。销售在意 deal；PM 在意用户价值；工程师在意系统。翻译。

Translating Between Functions (跨职能翻译)

The senior+ skill: translate the same fact for different audiences.

资深以上的技能：翻译同一事实给不同受众。

Phrases to Avoid (要避免的表达)

Cultural Notes (文化提示)

Each function has its own status game (每个职能有自己的地位博弈)

In some companies engineering is king; in others product is. In sales-led orgs, sales is. Read the org's power structure and don't assume your function's power transfers.

有的公司工程为王；有的产品为王。销售导向的组织里销售为王。读懂组织的权力结构，不要以为你职能的权力可以迁移。

Build allies in every function (每个职能都建盟友)

Senior+ engineers are known by name to PMs, designers, and even sales/finance leads. Build those relationships before you need favors.

资深以上的工程师在 PM、设计、甚至销售/财务 leads 那都有名。在需要帮忙之前就建立这些关系。

Translate, don't condescend (翻译，但不要俯视)

Translating is not "dumbing it down." It's framing the same idea in their world. PMs and execs are often very smart — they just have different metrics in their head.

翻译不是"降智"。是用他们的世界框定同一个想法。PM 和高管经常很聪明——只是脑子里的指标不同。

Don't slag on other functions (不要诋毁其他职能)

"Sales over-promises again." "Designers don't understand constraints." "PMs just push features." These are common venting and career-limiting. Other functions hear it eventually.

"销售又乱承诺。" "设计不懂限制。" "PM 只会催功能。" 这些常见的吐槽会限制职业。其他职能最终会听到。

Tips (小贴士)

• Learn each function's metrics — What do they actually get measured on? 学每个职能的考核指标。
• Spend 1 day shadowing other functions in your first 6 months — 30 min with sales, support, design. ROI is huge. 影子跟踪。
• Write for your audience — Same content, different framing. 同内容不同包装。
• Don't be the engineer who only talks to engineers — Senior+ requires range. 不要只会跟工程师说话。
• Assume good intent, always — Other functions aren't obstacles, they're partners. 假设善意。
