    关于进度


    今天一个朋友偶尔问了一个关于进度的问题,就把脑袋里的想法写了下来,作为存档
     
    已知代码 写完需要7天,说明文档3天,代码之后开始作文档,一共10天完成,完成权重按代码7:文档3
    1.如果代码完成90%,文档完成90% 那么说应用程序全部完成90%
    2.如果代码全的完成,文档做了两天,还差1/3每完成,也可以说应用程序完成了90%
    3.如果代码做了6天,完成6/7, 文档全完成,也是90%
    如果给领导看,他们看到的是一样的。
    但是如果代码和文档是两个不同的人写的呢,如果这两个人工资是不同的呢?
    如果代码的人是12000/月,写文档那个是6000/月
    那么整个应用程序,投资人需要看到他投入的12000/30*7+6000/30*3=3400块钱的产出。
    第一种情况,的话2800*90%+600*90%=3060=3400*90%
    第二种情况,2800+600*2/3=3200
    第三种情况,2800*6/7+600=3000
    同样看起来90%的进度,但是对投资人的结果其实是不一样的。
