  Real-world factors affecting Maintenance Cost
  
  1. The standard age of any software is considered up to 10 to 15 years.
  
  2. Softwares, which were meant to work on slow machines with less memory and storage capacity cannot keep themselves challenging against newly coming enhanced softwares on modern hardware.
  
  3. It becomes costly to maintain old software as technology improves.
  
  4. Most maintenance engineers are freshers and use trial and error method to rectify problem.
  
  5. The changes that can be made easily hurt the original structure of the software, making it hard for any subsequent changes.
  
  6. Changes are often left undocumented which may cause more conflicts in future.
