Write the kill rule before you look at the numbers

Описание и применение

Установите заранее правила прекращения работы канала, чтобы избежать преждевременного закрытия хороших каналов и продолжения работы неэффективных.

Задача

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

Результат

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

Рабочий процесс

• 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.
