Browse by method—each skill page covers outcome, steps, time, and difficulty. Add what you need in Hamster to guide your team from discovery to delivery.
Multiply Reach by Impact by Confidence (as a decimal), then divide by Effort in person-months. Only relative ranking matters—compare scores from the same session with the same units.
Map confidence to evidence—production data near 100%, strong qualitative signals lower, guesses much lower. Confidence multiplies through the score, so it should punish untested optimism.
Count users or events affected in a fixed period (usually a quarter). Use analytics where they exist; otherwise proxies like funnel volume, segment size, or support volume—and lower Confidence when you are guessing.
Multiply people by duration in months, include the roles you agreed count toward shipping, and use the same rules for every initiative. Round to sensible increments so the denominator stays comparable.
