The following numbers are invented to demonstrate the arithmetic. They are not benchmarks.
A five-step checklist is shown to 1,000 new accounts. Step one, import contacts: 820 complete. Step two, set up pipeline stages: 640. Step three, connect an email or messaging channel: 350. Step four, invite a colleague: 330. Step five, complete one real follow-up: 310.
Overall completion is 310 ÷ 1,000 = 31 percent. Measured per step against those who reached each one: 820 ÷ 1,000 = 82 percent, 640 ÷ 820 = 78 percent, 350 ÷ 640 = 55 percent, 330 ÷ 350 = 94 percent, 310 ÷ 330 = 94 percent.
Step three is losing forty-five percent of everyone who reaches it, while the two steps after it lose almost nobody. That is a single, specific, fixable problem, and it is invisible in the headline 31 percent. Note also the denominator used above is users who reached each step, not the original 1,000. Using the original cohort would report step five at 31 percent and imply a failure that is not there.
