- **Why Day 7 is high-value:** A callback request from the success team is an explicit buying signal — the lead is inviting direct sales contact, which dramatically shortens the consideration cycle. // 主动要求成功团队回电是明确的购买信号，意味着客户愿意直接对接销售，显著缩短决策周期。 - **Why it stays in C Pool:** The behavior adds only +1 (10 → 11) against a C→B threshold of 60; a single intent signal, however strong, doesn't yet justify a pool upgrade given the low cumulative engagement base. // 该行为仅加1分（10→11），距离60分的升级门槛仍远；单次强意向不足以在低累计互动基础上触发升级。 - **Precise actions to trigger:** Route the callback to a named success/sales owner within 24h, log the request as an opportunity in CRM, and queue a tailored follow-up (capability deck + discovery call agenda) rather than a full proposal yet. // 24小时内指派专属成功/销售负责人回电，将请求登记为CRM商机，并推送定制跟进（能力介绍+需求访谈议程），暂不发送完整方案。 - **Path to the 100-unit inquiry:** Use the callback to qualify scale, audience, and timeline, then gate a formal B2B proposal (with 100-seat pricing) behind completed discovery — converting intent into a sized, proposal-ready deal. // 借回电确认规模、受众与时间表，再在需求明确后发送含100席位报价的正式方案，把意向转化为可报价的成单机会。 - **Business outcome:** Fast callback response lifts conversion probability on high-intent leads and protects pipeline quality, while keeping the lead in C Pool avoids premature sales effort until score and qualification justify escalation. // 快速回电提升高意向线索的转化率并保障管道质量；暂留C池可避免在评分与资质未达标前过度投入销售资源。
