- **Day 7 survey = explicit intent signal**: Completing a post-video survey is active engagement, not passive viewing — it's the strongest early indicator of interest short of a direct inquiry. - 第7天完成问卷是主动行为，不是被动观看，属于除直接询盘外最强的早期兴趣信号。 - **Score math keeps them in C**: 21 vs. the 60 threshold — the behavior added +1 predictive point, but cumulative evidence (10 → 20 → 21) is still too thin for B. C Pool = early-stage nurture, not sales-ready. - 21分距60分门槛仍远，行为只带来+1预测分，累计证据不足；留在C池属于早期培育，尚未到销售跟进阶段。 - **Trigger low-friction, value-adding touches — not a proposal**: Send a thank-you with survey insights, a tailored case study (e.g., 100-seat corporate training rollout), and an invite to a deeper content asset. No B2B proposal or sales task yet — that would be premature and waste sales capacity. - 应触发低压力、增值型动作：感谢信+调研洞察、定制案例（如百人企业培训项目）、深度内容邀请；暂不生成方案或销售任务，避免过早消耗销售资源。 - **Build the 100-unit path gradually**: Each touch should probe scope signals (team size, budget owner, timeline) — a 100-unit inquiry needs proof of organizational need before it surfaces. Log survey answers as qualification data. - 每次触达都应试探规模信号（团队人数、预算决策人、时间线）；百人级询盘需要先积累组织需求证据，将问卷答案沉淀为资格数据。 - **Business outcome**: Higher pipeline quality at B/A entry, shorter sales cycles, and better conversion on large-unit deals — nurturing rigor upstream protects sales efficiency downstream. - 业务结果：进入B/A池时线索质量更高、销售周期更短、大单转化更好——前端培育的严谨性直接保障后端销售效率。
