**Lead Nurturing Brief — Global Skills (C → B Upgrade, Day 7)** **1. Day 7 behavior = high-intent signal, not passive traffic.** A callback request from the success team is a direct, sales-ready action; it converts anonymous interest into an identified buying conversation. / 请求成功团队回电是主动的销售意向行为，不是被动浏览；它把匿名兴趣变成有明确联系人的商机。 **2. Score jump (55 → 77) crosses the 60 threshold → automatic C → B upgrade.** AI weights active request behaviors heavily, so the predicted score gain (+22) is enough to move the lead into a higher-touch pool. / AI 对主动请求类行为权重很高，预测分上升 22 分越过 60 分阈值，因此自动从 C 池升到 B 池。 **3. Precise actions to trigger now:** - Assign an account owner and schedule the callback within 24h (SLA). - Send a tailored proposal with pricing tiers for volume training. - Create a follow-up task set: discovery call → needs assessment → quote. / 立即指派销售负责人并在 24 小时内回电；发送含批量培训阶梯报价的定制方案；建立“需求确认—方案—报价”的跟进任务链。 **4. Why it matters for the 100-unit distribution inquiry.** B Pool = qualified pipeline with higher conversion rate and larger deal size; structured follow-up protects the deal from stalling before a 100-unit quote is issued. / B 池代表合格商机，转化率与客单价更高；结构化跟进可避免商机在百套报价前流失。 **5. Next milestone: B → A at 120.** Recommended actions (live demo, stakeholder mapping, pilot proposal) can carry the lead from 77 toward 120 and into A Pool for enterprise-level handling. / 下一个里程碑是 120 分升入 A 池；通过演示、决策链梳理和试点方案，可将分数从 77 推向 120，进入大客户管理流程。
