The method

Time-box the next investment

Continued investment should become a bounded test of a remaining important assumption.

When to use it

  • Iteration has not improved retention, growth, or core outcomes.

Ask yourself

  • The product is not improving. Should we persist?

Put it into action

  • Rank experiments that could change the trajectory, set review dates and measures, then decide to continue, narrow, or stop.

Keep these limits in mind

  • Do not copy a fixed number of experiments or deadlines. Account for feedback cycles and obligations to users, employees, and partners when exiting.
