How to use these cases

Read the prompt, answer out loud for ten minutes, then compare. Each case uses one of the module's two methods:

  • The Value Moment method for choosing metrics, setting goals and making trade-off calls: name the value, find the moment, make it a number, stress-test it, guard it.
  • The Change Drill for any metric that moved, including experiment results: check it's real, size it, slice it, line up suspects, settle it.

All products are fictional and all numbers are invented, rounded for easy arithmetic.
