Use when someone is building or running a new product (C-end or small-B SaaS, 0→1 / 1→10) and needs to know which stage it is at, whether it has passed the current gate, or what to do next. Symptoms include "should I start advertising / scaling now", "users love it on first try — is this PMF", "DAU is growing so we're good", "我做了访谈接下来做什么", confusing activation with retention, jumping stages, judging progress by feelings/口头反馈 instead of behavioral data, or needing to decide whether this staged-validation framework even applies (vs contract/compliance/internal-tool/mature/creative projects). Keywords: AARRR, Demo, MVP, PMF, GTM, MTU, 激活率, 留存曲线, Sean Ellis, LTV/CAC, 通关, 阶段评审, 止损.

把产品按 Demo → MVP → PMF → GTM → MTU 五关推进:每关只回答一个核心问题、验一个核心假设、看一个核心指标;前一关没过不许进下一关。核心是把"感觉做对了"换成"数据证明通关了"。
