A customer wants to raise their daily ATM withdrawal limit at a branch. Today the teller fills out a paper form, scans it and emails it to the back office. The back office updates the card system the next day and texts the customer, so it takes about two days end to end. You just joined the project and need to map this current-state process. How do you go about it, and what goes on the map?

客户想在网点把借记卡每日取现额度调高。现在的做法是柜员填纸质表、扫描后用邮件发给后台，后台第二天在卡系统里改完，再发短信通知客户，前后平均要 2 天。你刚进项目组，要先把这个现状流程画出来，你会怎么做？图上要标出哪些东西？
