神话般的人每月每个开发人员每天10行-大型项目有多近? [英] Mythical man month 10 lines per developer day - how close on large projects?

问题描述

每个人总是说他们可以击败神话人月"中的每个开发人员每天10条线"，并且开始一个项目，我通常一天可以得到几百条线.

Everybody always says that they can beat the "10 lines per developer per day" from the "Mythical Man Month", and starting a project, I can usually get a couple hundred lines in in a day.

但是在我以前的雇主那里，所有的开发人员都很敏锐，但这是一个大型项目，超过一百万行代码，具有非常繁琐的认证要求，并且与其他数百万行的项目接口.在某些时候，出于好奇心的考虑，我在小组中的运输产品中绘制了代码行(不算我们开发的工具)，并且可以肯定地，逐渐地，每个开发人员每天净增加约12行.不计算变更，测试代码或开发人员并非每天都在处理实际项目代码的事实.

But at my previous employer, all the developers were very sharp, but it was a large project, over a million lines of code, with very onerous certification requirements, and interfacing with other multiple-million line projects. At some point, as an exercise in curiosity, I plotted lines of code in the shipping product in my group (not counting tools we developed), and sure enough, incrementally, it came to around 12 lines net add per developer per day. Not counting changes, test code, or the fact that developers weren't working on the actual project code every day.

其他人的情况如何?您将面对什么样的要求(我想这是一个因素)?

How are other people doing? And what sort of requirements do you face (I imagine its a factor)?

推荐答案

我认为添加的行数高度依赖于项目的状态，添加到新项目的比率将大大高于项目的比率.一个开始的项目.

I think the number of lines added is highly dependent upon the state of the project, the rate of adding to a new project will be much higher than the rate of a starting project.

两者之间的工作是不同的-在大型项目中，您通常会花费大部分时间来确定零件之间的关系，而实际上只花费很少的时间来更改/添加零件.而在一个新项目中-您通常会写...直到它足够大并且速度降低.

The work is different between the two - at a large project you usually spend most of the time figuring the relationships between the parts, and only a small amount to actually changing/adding. whereas in a new project - you mostly write... until it's big enough and the rate decreases.
