**Lead Nurturing Analysis: Day 7 Callback Request (C Pool, Score 18/60)** - **High-value behavior = explicit buying signal.** A callback request shifts the lead from passive browsing to active human contact, signaling budget, authority, or urgency. / 主动要求回电是明确的购买信号，代表客户已从被动浏览转为主动接触，通常意味着预算、决策权或紧迫需求。 - **Still C Pool: score gap too wide.** Day 7 predicted score is 18 vs. the C→B threshold of 60. One strong signal doesn't override six days of low engagement (cumulative 10). / 第7天预测分仅18分，距C升B的60分门槛差距过大；单次高价值行为无法弥补前6天累计仅10分的低互动。 - **Trigger: sales follow-up task, not full proposal yet.** Route to success team for a discovery call/SQL qualification; hold the formal B2B proposal until engagement depth justifies it. / 触发动作：生成销售跟进任务，由成功团队做需求挖掘与商机资格评估；暂缓正式B2B方案，避免资源错配。 - **Enrich lead profile during the call.** Capture training volume, timeline, and department scope to feed the AI model and accelerate future scoring. / 通话中补充培训规模、时间表和部门范围等画像信息，反哺AI模型，加速后续评分提升。 - **Path to 100-unit inquiry.** Sustained engagement post-callback (proposal views, repeat sessions, multi-stakeholder touches) is what pushes score past 60 → B upgrade → proposal + opportunity creation → scalable 100-unit distribution deal. / 回电后的持续互动（方案浏览、重复观看、多角色触达）才能推动评分突破60分→升级至B池→自动发方案并建商机→最终承接100套规模的分销询单。 **Net effect:** callback raises intent quality, but pool discipline prevents premature sales spend — protecting conversion rate and rep efficiency until the deal is truly qualified. / **核心逻辑：** 回电提升意向质量，但分池纪律避免过早投入销售资源，保障转化率与人效，直到商机真正成熟。
