We're rebuilding the debit card dispute system. The department head's process map shows every dispute closed within 10 business days, but when you sit with the frontline team you see that about 30% of cases need data from three other systems and take 14 days on average. The head wants requirements written to that process map and scope frozen in two weeks. What do you do?

借记卡争议处理系统要重构，部门负责人给的流程图显示争议都在 10 个营业日内结案。但你旁听一线时发现，约 30% 的案件要切到另外三个系统查数据，平均要 14 天。负责人要求按这张流程图写需求，两周后冻结范围。你怎么办？
