# Product Market Fit (PMF)
在製造產品之前,必須要確認這是有市場的,我們稱之為Product-Market Fit(PMF)
你要思考什麼樣的人會買你的產品,他幾歲、男性女性、住哪裡做什麼工作、有什麼興趣或生活習慣等等資訊,越多細節越好,將這些資訊收集好後,製作「人物誌」(Buyer Persona)。
### Popular metrics
The 40% rule
---
One metric for product/market fit is if at least 40% percent of surveyed customers indicate that **they would be "very disappointed" if they no longer have access to a particular product or service**.
Analytics metrics
---
1. Bounce Rate
2. Time on Site
3. Pages per Visit
4. Returning Visitors
5. Customer Lifetime Value.
If these 5 metrics are **above average and your 40% rule is met**, you'll know you have a Product / Market Fit company.

- Take Away:
- 如果你的產品是被需要的話,使用者自然而來就會被吸引來使用,並且留下來。使用者**並不會因為你的註冊流程好或不好,而決定要不要使用**。
- **永遠都是先達到「PMF」再追求「成長」。**
