降低软件维护预算的趋势？ [英] A Trend Towards Lower Software Maintenance Budgets?
问题描述
软件维护是软件开发的重要组成部分
活动，但它的讨论也较少。最近的民意调查显示，b
显示软件开发预算中的部分维护费用已经下降。为什么？
问题：您的软件开发预算的百分比是多少？b $ b用于维护。维护被定义为
纠正，增强和优化已部署软件的过程。
预算的25％或更少......... ..37％
26％至50％的预算............ 27％
51％至75％的预算............ 24％
超过预算的75％......... 12％
参与人数：433
美国的年度维护费用估计超过70美元。根据上一个b
世纪产生的不同研究，维护费用应占总寿命的66％至90％b / b $ b $周期成本。我们在调查中可以看到，大部分
参与者估计他们的维护预算低于50％
的门槛。如果我们接受这些数字代表
修改的情况，可以用很多假设来解释它。

Software maintenance is an important part of the software development
activity, but it is also the less discussed. A recent poll seems to
show that the part of maintenance in software development budget is
going down. Why?
Question: what percentage of your software development budget is
devoted to maintenance. Maintenance is defined as process of
correcting, enhancing and optimising deployed software.
25% or less of the budget ...........37%
26% to 50% of the budget ............27%
51% to 75% of the budget ............24%
more than 75% of the budget .........12%
Number of participants: 433
The annual maintenance costs in the US are estimated at over $ 70
billion. According to the different studies produced in the last
century, maintenance should cost between 66% and 90% of the total life
cycle costs. We can see in our survey that the majority of the
participants estimate their maintenance budget below the 50%
threshold. If we accept that these numbers are representative of a
modified situation, many hypothesis can be made to explain it.
