We split our card customers into three groups: transactors who pay in full are 50% of accounts at 60 dollars annual profit each, revolvers are 30% at 200 dollars, and inactive accounts are 20% at minus 20 dollars. The budget only covers one group this year. Which group do you go after first, and what do you do?

我们把信用卡客户分成三群：全额还款的交易型占50%，单户年利润60美元；循环型占30%，年利润200美元；不活跃的占20%，年利润负20美元。老板说今年预算只够针对一群做动作，你先做哪一群、做什么？
