Which option is the clearest success criterion: “Does not leak” or “Leaks less than 1 drop in 1 minute”?
Which option is the clearest success criterion: “Does not leak” or “Leaks less than 1 drop in 1 minute”?
Tap to reveal answer
Leaks less than 1 drop in 1 minute. Quantifying leaks allows objective pass/fail testing.

Find the success criterion: “Must be safe and use only tape; should protect an egg from 30 cm.”
Find the success criterion: “Must be safe and use only tape; should protect an egg from 30 cm.”
