- **Day 7 callback request signals active buying intent, not passive browsing.** In B2B training sales, asking a human to call back is a deliberate, high-friction action — it usually means budget, need, or timeline is real. **中文：** 主动要求回电属于高意向信号，不是随便看看；在B2B培训场景中，这通常意味着预算、需求或时间表已经相对明确。 - **Score rises 10 → 19, but stays far below the 60 C→B threshold.** One strong signal is not enough to reclassify a lead; AI needs sustained engagement (repeat visits, video watches, proposal opens) to confirm intent and reduce false positives. **中文：** 分数从10升到19，但仍远低于60的升级线；AI不会因单次强信号就升级，需要持续互动来验证意向，避免误判。 - **Trigger a sales-assisted follow-up, not an automated proposal yet.** Route to success team, set a 24-hour callback SLA, log call outcome, and schedule a needs-discovery session — human touch now, automation later. **中文：** 应先触发销售/成功团队跟进，而不是直接自动发方案；设置24小时回电SLA、记录通话结果，并安排需求诊断会——先人工，后自动化。 - **Use the callback to qualify the 100-unit distribution inquiry.** Confirm learner volume, delivery format, timeline, and decision-makers; if qualified, then generate a tailored B2B proposal and move toward B-pool nurturing. **中文：** 用这次回电去验证100套分发询盘的真实性：确认学员规模、交付形式、时间表和决策人；若确认合格，再输出定制B2B方案，并推动进入B池培育。 - **Business outcome: protect pipeline quality and shorten sales cycle.** Precise triggering converts a warm signal into a qualified opportunity without over-nurturing low-score leads — improving conversion rate and sales efficiency. **中文：** 业务结果是保护管道质量、缩短成交周期；精准触发能把热度转化为合格商机，同时避免对低分线索过度培育，从而提升转化率和销售效率。
