Write the kill rule before you look at the numbers

说明与用途

提前设定终止规则，避免过早关闭有效渠道或长期保留无效渠道。

问题

Decisions about marketing channels are often made after seeing data, leading to premature termination of good channels or prolonged support of bad ones.

结果

Implementing pre‑registered thresholds reduces decision bias, ensures consistent evaluation, and improves resource allocation across marketing channels.

工作流

• 1. Identify the channel to evaluate.
• 2. Write a kill rule: "If fewer than N results after X units, the channel is out."
• 3. Write a keep rule with corresponding numbers.
• 4. Record the rules and the date to review results in a file.
• 5. Do not alter the rules until the review date.
• 6. On the review date, compare results to the thresholds and act accordingly.

证据

If fewer than N results after X units, the channel is out.

Both are the same error: deciding after seeing the data instead of before.
