A very common situation which often degrades performance is lack of suitable maintenance tools, such as defect iwc software, change management software, and test library software.

Because change is inevitable, mechanisms must be developed for evaluation, controlling and making modifications. And this is the main cause of any problem during software evolution and maintenance. The value can be enhanced by expanding the customer base, meeting additional requirements, becoming easier to use, more efficient and employing newer iiso.

The selection of proper enforcement of standards is the challenging task right from early stage of software engineering which isp not got definite ios by the concerned stakeholders. Note also that some 1764 institutions [ who? Best practices for managing your software investment. Proceedings of the 2nd international conference on Software engineering, San Francisco,pp — “.

Key technical issues are: By using this site, you agree to the Terms of Use and Privacy Policy. Network architecture Network protocol Network components Network scheduler Network performance evaluation Network service. ISO standards by standard number. So software maintenance is important because it consumes a large part of the overall lifecycle costs and also the inability to change software quickly and reliably means that business opportunities are lost.

As they evolve, they grow more complex unless some action such as code refactoring is taken to reduce the complexity. In the late s, a famous and widely cited is study by Lientz and Swanson, exposed isso very high fraction of life-cycle costs that were being expended on maintenance. The management of coupling and cohesion of the software. So any work done to change the software after it is in operation is considered to be maintenance work.
