- **Day 7 behavior = deliberate buying intent.** Requesting a callback is a self-initiated, high-cost action—stronger than passive views or video watches; it usually signals active evaluation and near-term decision. - 第7天的行为代表明确的购买意图。主动预约回电比浏览或看视频成本更高，通常意味着客户已进入实际评估、接近决策阶段。 - **AI score jumps because intent outweighs volume.** Cumulative behavior built the score to 56; the callback adds a high-weight intent signal, pushing the predicted score to 84 and crossing the C→B threshold of 60. - AI评分跃升是因为“意图”比“数量”更重要。前6天累积到56分，回电请求属于高权重意图信号，使预测分升至84，越过C→B的60分门槛。 - **Pool upgrade = prioritization, not closing.** C→B means the lead is now sales-ready and should get structured, resource-backed nurturing; it is still 36 points from A (120), so it needs qualification before heavy investment. - 升级到B池意味着优先跟进，而不是直接成交。客户已具备销售跟进条件，但距离A池120分还差36分，需要先做需求确认再投入更多资源。 - **Trigger precise actions: proposal + sales follow-up.** System should: (a) alert success/sales team to call back within 24h, (b) send a tailored B2B training proposal, (c) schedule a discovery/needs-analysis call, (d) auto-create a follow-up task with 3–5 day cadence. - 触发动作应精准：24小时内安排回电、发送定制化B2B培训方案、安排需求诊断会议，并自动创建3–5天节奏的跟进任务。 - **Business outcome: higher conversion on 100-unit inquiry.** Faster, relevant follow-up raises response rate and shortens sales cycle, turning a mid-funnel lead into a qualified 100-unit distribution opportunity—improving pipeline quality and sales efficiency. - 业务结果是提高100套分销询盘的转化率。更快、更相关的跟进能提升响应率、缩短销售周期，把中漏斗线索转化为合格的100套分销机会，从而提升商机质量和销售效率。
