Software Maintenance

At A2GSoft technologies, we offer maintenance services for software applications as well as websites based on the below mentioned four primary areas of software application maintenance that are important for long term stability, sustainability, and maintenance of a software product.

Software Maintenance is categorized in four different classes mentioned below:

  • Corrective Software Maintenance for fixing issues or defects reported by users

  • Preventive Software Maintenance for finding and correcting problems or potential problems before they are noticed by users

  • Perfective Software Maintenance for improving performance and stability of software applications

  • Adaptive Software Maintenance for keeping products usable in a changing environment

The survey showed that around 75% of the maintenance effort was on the first two types, and error correction consumed about 21%. Many subsequent studies suggest a similar magnitude of the problem. Studies show that contribution of end user is crucial during the new requirement data gathering and analysis. And this is the main cause of any problem during software evolution and maintenance. 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.
