ExplanationWorkload is measured in person-days (人日), the amount one standard worker does in a day (person-months when counted by month), found by multiplying headcount by days. A less productive worker is first counted as a fraction of a standard worker by multiplying by their productivity ratio. Members report progress and problems to the project manager, who pulls the reports together for decisions on the whole project.
AnalogyIt is like a singer in a choir. Instead of conducting, each singer rehearses and polishes their own part and carries one piece of the overall sound.
Memory hookMember comes from the Latin membrum, "limb", a part of the body. Set the limbs, each working its own post, against the head that directs the whole, and the difference in roles becomes clear.
