A Framework for the Management of Preventive Maintenance

软件在我们的日常生活中扮演着至关重要的角色，因为我们越来越多的活动涉及使用软件系统，从在线银行交易和电子政务服务到手机中的移动的应用程序。然而，软件系统必须不断更新，以满足新的客户需求，修复错误，提高性能和响应时间，并采用新的技术和基础设施。执行上述维护活动的成本在很大程度上取决于软件系统的基本设计质量。一般来说，设计不好的软件系统需要更多的时间和精力来进行更改，反之亦然。

Software plays a critical role in our everyday life as more and more of our activities involve the use of software systems from online bank transactions and e-government services to mobile applications in our phones. However, software systems must be constantly updated to address new customer needs, fix errors, improve the performance and response time, and adopt new technologies and infrastructures. The cost of performing the aforementioned maintenance activities highly depends on the underlying design quality of the software systems. In general, software systems that are not well-designed require much more time and effort to make changes, and vice versa.
