ABSTRACT

The maintainability of the software system is becoming a very important characteristic due to growth in demand of quality software system. Software maintainability means the ease with which a software system or component can be modified to correct faults, improve performance or other attributes or adapt to a changed environment. The selection of best maintainability model is prime concern for developing quality software system. Every software maintainability model has some sub-characteristics which impact on maintainability directly or indirectly. This paper presents different maintainability models from various standards and quality models define its sub-characteristics and then perform analytical comparison of these sub-characteristics.
