Abstract

Individual contribution and performance assessment is a stan-dard practice conducted in organizations to measure the value addition by various contributors. Accurate measure-ment of individual contributions based on pre-defined ob-jectives, roles and Key Performance Indicators (KPIs) is a challenging task. In this paper, we propose a contribution and performance assessment framework (called as Samik-sha) in the context of Software Maintenance. The focus of the study presented in this paper is Software Maintenance Activities (such as bug fixing and feature enhancement) per-formed by bug reporters, bug triagers, bug fixers, software developers, quality assurance and project managers facili-tated by an Issue Tracking System. We present the result of a survey that we conducted to un-derstand practitioner’s perspective and experience (specifi-cally on the topic of contribution assessment for software maintenance professionals). We propose several performance metrics covering different aspects (such as number of bugs fixed weighted by priority and quality of bugs reported) and various roles (such as bug reporter and bug fixer). We con-duct a series of experiments on Google Chromium Project data (extracting data from the issue tracker for Google Chr-omium Project) and present results demonstrating the ef-fectiveness of our proposed framework.
