JSE_V3_N3_A1 Sunil Kumar Singh Kumar Rajnish Kamal K. Mehta Journal on Software Engineering 2230 – 7168 3 3 1 5 Object-Oriented, Inheritance Tree, Metrics, Classes, Class Hierarchy Various Object-Oriented (OO) inheritance metrics have been proposed and their reviews are available in the literature. This paper presents the empirical approach to OO inheritance tree metric proposed by Rajnish and Bhattacherje and an attempt has been made to define an empirical relation between software development times with respect to its dependence upon inheritance tree metric values. An attempt has also been made to analyze the various dependencies of development time of a program upon its inheritance tree metric values. A statistical analysis was done and focus was on how closely the inheritance tree metrics were correlated to the development time of various C++ class hierarchies.
