做技术方案别只画架构图

我以前做方案时吃过亏,图画得很好看,客户也点头,真正交付时才发现接口限流、数据归属、账号体系、旧系统字段这些问题都没谈清楚。架构图只能说明你想怎么连,不能说明这个方案能不能落地。 现在我写方案会先问几个土问题:谁负责维护,数据从哪里来,失败了谁重试,日志谁能看,权限怎么给,费用怎么算,旧流程怎么退回去。尤其是系统集成项目,最麻烦的经常不是技术栈,而是双方对"完成"的理解不一样。 原型也要尽早做,不要等合同都签完才发现 API 文档和真实返回不一样。能用一周把登录、数据同步、错误处理跑一遍,就不要花三周写一份没人会按原样执行的方案。技术方案最后拼的是细节和交接,不是图上有多少框。
