需求调研
多服务厅预约小程序：随着信息技术的快速发展和移动互联网的普及，越来越多的服务行业开始向线上转型, 传统的预约方式往往效率低下，用户需耗费大量时间进行电话预约或现场排队，服务厅预约小程序集多种服务于一体，可以提高服务效率、提升用户体验。 用户可以浏览不同服务厅的位置、服务项目和服务时间，用户可以选择日期、时间段和人数，然后进行预约。
功能设计
公告通知，用户预约，签到核销， 管理者可以自定义预约要填写的内容，比如姓名、性别、年龄、身份证、手机号等，后台预约管理，后台预约名单管理和导出Excel，后台设置预约时段和人数上线，后台管理最新通知公告，后台用户管理，后台服务厅管理，服务厅管理员设定等功能
