商业案例的ReSharper [英] Business Case for ReSharper

问题描述

我们正努力让ReSharper的介绍我们的公司，但它必须为所有的开发人员。管理要我们证明成本与商业案例。

我知道如何去获得证明ReSharper的将有利于业务。你可以从它那里得到什么样的统计数据？

解决方案

  

我知道如何去获得证明ReSharper的将惠及企业。

如果他们要求一个商业案例，他们没有要求的证明，只是某种他们的投资可能收益的事实为依据的估计。

因此​​，例如： 牌照费（说）$ 250元的开发者，开发成本（说）每年$ 50,000。 与ReSharper的开发人员的成本比没有ReSharper的开发人员更0.5％。

这是给你一个基本的财务模型 - 如果你得到超过0.5％，生产率提高，那么它是值得的，如果你少了，其实不然。一些公司债券申请投资回报（ROI）系数最低回报 - 因此，如果系数为1.2，那么你就必须表现出0.7％的利益得到批准。的因素是非常不太可能超过3

您可以调整该模型 - 德preciate 3年以上的牌照，包括采购成本，改变资金等成本，但一个简单的，保守的模式很可能拥有最广泛的吸引力。

然后，所有你需要的是一些证据，你获得超过0.5％的生产率的提高。你可以运行一个基准，或与少数开发商为这个试点。挑选一些典型的任务，有和没有ReSharper的计时他们。有提供30天的试用版本，所以你可能在你需要购买之前运行试点。

在ReSharper的主页上的PDF声称35％的生产力增长 - 你可以采取与少许盐，但除非多数民众赞成夸大了70倍，它仍然是一个有价值的投资。在网络上的建议，和开发商声称用自己的钱购买它的数字表明，它是不是野生的夸张。

在present业务的情况下，你可能想说明这一比例为一美元的价值了。

开发只花一天的一部分，在他们的IDE，那么你或许应该调整，因为向下的预期收益。的实数大概是在20％和80％，但该范围的下端可能不是一个政治上可接受的编号，以present。你对什么感兴趣，输出的比例是受投资。

我没有与Jetbrains的任何联系 - 我回答如何使一个商业案例，不会出售许可证的问题！从我工作的传闻是，谁使用ReSharper的开发商只有好的东西说些什么。在一些非常特殊的情况下，它通过自动必须应用在很多文件机械任务保存几个星期或几个月。时间很难衡量，但由于开发者使用的时候它所有的休息，所以一定要得到一些真正的价值出来。

有一个质量的说法太 - 你可以衡量这是一个生产率的提高，或节约成本，或者只是一个额外的参数 - 视质量问题是如何在你的公司认为在管理水平

。

祝您的商业案例。

We are trying to get ReSharper introduced to our company but it would have to be for all developers. Management want us to justify the cost with a business case.

I am unsure how to go about getting proof that ReSharper will benefit the business. What kind of statistics can you get from it?

解决方案

I am unsure how to go about getting proof that Resharper will benefit the business.

If they asked for a business case, they're not asking for proof, just some kind of fact-based estimate of the likely return on their investment.

So, for example: A license costs (say) $250 per developer, a developer costs (say) $50,000 per year. A developer with Resharper costs 0.5% more than a developer without Resharper.

That gives you a basic financial model - if you get more than a 0.5% productivity gain, then it's worth it, if you get less, it isn't. Some corporates apply a minimum return on investment (ROI) factor - so if the factor is 1.2, then you would have to show a 0.7% benefit to get approval. The factor is very unlikely to be more than 3.

You could tweak that model - depreciate the license over 3 years, include the procurement costs, changing cost of capital, etc., but a simple, conservative model is likely to have the broadest appeal.

Then all you need is some evidence that you get more than a 0.5% productivity improvement. You could run a benchmark, or a pilot with a small number of developers for this. Pick some typical tasks and time them with and without Resharper. There is a 30 day trial version available so you could run a pilot before you have to purchase.

The PDF on the Resharper home page claims a 35% productivity increase - you can take that with a pinch of salt, but unless that's exaggerated by a factor of 70, it's still a worthwhile investment. The number of recommendations on the web, and developers claiming to buy it with their own money suggest that it isn't a wild exaggeration.

When you present the business case, you might like to illustrate that percentage as a dollar value too.

Developers only spend part of their day in their IDE, so you should probably adjust the expected returns downwards because of that. The real number is probably between 20% and 80%, but the lower end of the range might not be a politically acceptable number to present. You're interested in what proportion of the output is affected by the investment.

I don't have any connection with Jetbrains - and I'm answering a question about how to make a business case, not selling licenses! The anecdotal evidence from where I work is that the developers who have used Resharper have only good things to say about it. In some very specific cases it has saved weeks or months by automating mechanical tasks that have to be applied over a lot of files. The rest of the time it's hard to measure, but since the developers use it all of the time, they must be getting some real value out of it.

There's a quality argument too - you could measure this as a productivity increase, or a cost saving, or just an additional argument - depending on how quality issues are perceived at management level in your company.

Good luck with your business case.
