前言
好多职场小白第一次做需求岗的时候，往往不知道该做哪些工作，其实在我看来需求岗一个是要客户沟通需求，制作原型图，另外一个工作是写需求规格说明书，规格说明书的目的一个是给客户看，看客户的要求有没有遗漏，另一个是给程序员看，让程序员了解系统需要做哪些功能。
规格说明书还是蛮重要的，因为它是项目管理的起点，规格说明书要梳理清楚功能点，需要有经验的程序员依据功能点来估算工作量，而工作量的估算又是项目预算的重要来源，也是后续项目排期的重要依据。
项目概述
项目背景
本次实战项目来源于笔者对日常生活的观察，笔者的姐姐开了一家海鲜店，日常依靠微信的工具开展营销工作，她将顾客组建了微信群进行日常的销售推广，对于货品的介绍主要依托于朋友圈的推送，如果下个定义的话那么她就是微商。
建设目标
依托于微信小程序的功能，给笔者的姐姐搭建一套线上的商城，方便她宣传产品，也方便顾客进行在线选购。
建设内容
首页：要有活动的推荐，顾客可以按照类别浏览商品，可以将热销商品在首页上展示；
分类：顾客可以按照类别快速的选购商品；
购物车：顾客可以浏览购物车里已经选购的商品，可以下订单；
我的：方便顾客实时查看订单的情况，对于成为会员的顾客可以查看他的余额，可以在线充值。
需求概述
业务流程
业务流程比较简单，就是浏览商品-》选购-》下单
总体架构
这个我们就比较牛一点，因为对于传统架构其实没啥优势，但是我们这个是互联网应用还是比较有优势的
用户角色
顾客：购买商品的人
商家：发布商品的人
