Abstract—The work presented in this paper measures the contribution of developers towards evolved structural design of software systems. Measuring the contribution of developers is useful for project managers who manage the development process. Project managers can empirically identify developers who made changes to the structural design and compare among them based on their contributions. The proposed measures help to understand the nature of developers’ code changes activities. The process of calculating the measures is based on the historical code changes committed by developers. Specifically, code changes that affect the corresponding UML class diagram representation of the source code. Both type and amount of previous changes to class elements are used to measure the design contributions. The proposed measures are helpful for open source projects where no detailed information is available about various developers involved in the development process. A tool has been developed to automatically measure the contributions based on archived historical code changes. The measures have been applied on two open source projects. Results showed that only small number of developers have the major design contributions.

Index Terms—Software development and design, software measurements, software evolution.
