Periodic KYC review for high-risk clients has three steps. First, requesting documents from the client takes about 4 days of waiting. Second, analyst review is 2 hours of actual work but sits in a queue for 3 days. Third, QC review is 30 minutes with a 1-day queue. On top of that, 30% of cases get kicked back by QC and redo both review and QC once. What is the average cycle time, how much of it is real work, and which step do you fix first?

高风险客户的 KYC 定期复审分三步。第一步向客户要材料，平均等 4 天。第二步分析师审核，实际干活 2 小时，但要排队 3 天。第三步 QC 复核半小时，排队 1 天。另外有 30% 的案子会被 QC 退回，重做一遍审核和复核。平均一个案子要多久？真正干活的时间占多少？你先改哪一步？
