人事の話。『適正人員の算出方法』〜これをやらずに、「マネジメントができている」なんて言えない！〜　＜坂本健＞

When a frontline manager complains, "We don't have enough people!" and you ask them, "So how many people do we need?", you usually won't get a reasonable answer. "Maybe we need two or three more people?" A manager who gives an answer like this can't be trusted to have optimally improved the work of their organization, so it raises the question, "Couldn't we actually get by with the current number of staff if we manage it a bit?" And so, at some point, the number of staff has come to be determined by the negotiating power of HR and the frontline, which is the reality for many Japanese companies. If we continue to do things this vague and careless, we won't be able to solve the problems of overtime and labor shortages. So today, I'll introduce you to a method for calculating the optimum number of staff.
