- **High-value signal, not yet buying signal.** A post-video survey shows active engagement and gives us qualification data (role, training needs, budget hints). 完成视频后问卷是高价值互动，说明客户愿意投入时间并提供了资格信息，但还不等于购买意向。 - **Score math keeps them in C.** Day 1 = 14, Days 1–6 cumulative = 44, Day 7 predicted = 48 — still 12 points below the C→B threshold of 60. 分数从14到48仍未达到升级线60，差距12分，所以AI判定暂不升级，保持C池。 - **Trigger nurture, not sales handoff.** Send a personalized content follow-up (case study / short ROI guide) and a low-friction CTA; log survey answers to enrich the profile. 触发培育动作而非销售交接：推送个性化案例或ROI简析，设置低门槛CTA，并把问卷答案写入客户画像。 - **Pre-qualify the 100-unit inquiry.** Use the survey data to confirm team size and training scope; if 100+ seats are indicated, flag for B-pool review and route to inside sales for a scoping call. 用问卷信息确认团队规模和培训范围；若显示100+席位，标记进入B池复核并转给内销做需求确认电话。 - **Business outcome:** sustained nurturing improves pipeline quality and keeps sales effort focused where conversion probability is highest. 业务结果：持续培育提升商机质量，把销售精力集中在转化概率最高的客户上。
