Changeability has a direct relation to software maintainability and has a major role in providing high quality maintainable and trustworthy software. The concept of Changeability is a major factor when we design and develop software and its constituents. Developing programs and its constituent components with good changeability continually improves and simplifies test operations and maintenance during and after implementation. It encourages and supports improvement in software quality at design stage in the development of software. The research here highlights the importance of changeability broadly and also as an important aspect of software quality.

In this paper a correlation between the major attributes of object oriented design and changeability has been ascertained. A changeability evaluation model using multiple linear regression has been proposed for object oriented design. The validation of the proposed changeability evaluation model is made known by means of experimental tests and the results show that the model is highly significant.
