Changes to the hardware, operating system, software dependencies, and organizational business rules and policies are handled in adaptive maintenance. Software maintenance in software engineering is the modification of a software product after delivery to correct faults, to improve performance or other attributes. In a paper for the 27th International Conference on Software Quality Management in 2019[10], John Estdale introduced the term “maintenance debt” for maintenance needs generated by an implementation’s dependence on external IT factors such as libraries, platforms and tools, that have become obsolescent [11]. The maintainability index is calculated with certain formulae from lines-of-code measures, McCabe measures and Halstead complexity measures. Estdale defines "Maintenance Debt"[11] as: the gap between the current implementation state of an application and the ideal, using only functionality of external components that is fully maintained and supported.
