**Day 7 Lead Nurturing Analysis – Global Skills** - **High-value signal but low score weight.** A callback request to the success team is a strong buying intent signal — the lead is proactively seeking human contact. However, one interaction (score +4, 10→14) does not offset the low engagement base. **中文：** 主动请求回电是高购买意向信号，代表客户主动寻求人工接触；但单次互动仅带来 4 分增量（10→14），无法抵消此前低互动基数的缺口。 - **Stay in C Pool: threshold logic.** Upgrade to B requires 60. At 14, the lead is still 46 points below threshold, so the AI correctly withholds upgrade to avoid false positives and wasted sales capacity. **中文：** 升级 B 池需 60 分，当前 14 分距阈值仍差 46 分；AI 据此不升级，避免误判和销售资源浪费。 - **Trigger precise low-cost nurturing actions.** Auto-schedule a success-team callback within 24h, send a tailored training solution one-pager, and log the callback into CRM as a warm signal for review. **中文：** 触发低成本精准动作：24 小时内安排成功团队回电、发送定制培训方案简介、并将回电记录写入 CRM 作为暖信号供复核。 - **Business impact: warm lead kept alive at low cost.** Keeping the lead in C with a timely callback preserves engagement without over-investing sales time, increasing the chance the lead progresses toward A and a 100-unit distribution inquiry. **中文：** 业务价值：以低成本维持暖线索活跃度，避免过度投入销售时间，从而提升其逐步升级至 A 池并转化为 100 套分销询盘的概率。 - **Path to 100-unit inquiry.** Each qualifying interaction (proposal view, meeting, repeat callback) accumulates score; once ≥60, C→B upgrade auto-triggers a B2B proposal and sales follow-up task — the standard gateway to large-volume distribution deals. **中文：** 通向 100 套询盘的路径：方案浏览、会议、重复回电等有效互动持续累积分数；一旦达到 60 分即自动 C→B 升级，触发 B2B 提案与销售跟进任务，这是大额分销订单的标准入口。
