This study has taken a step toward developing and testing a psychometric scale to measure the practices of Open Source Software Development (OSSD) within industries in India, thereby addressing the absence of context-specific instruments designed for emerging economies. The study employed an empirical design consisting essentially of two phases, each tied to an established scale for the OSSD in the Indian context. In the first phase, Exploratory factor analysis (EFA) was used to analyse 480 respondents from organizations, while Confirmatory factor analysis (CFA) scientifically tested the two-factor, ten-item scale, which eventually appeared to have a strong model fit, doing justice to both the Product Speed and Product Quality dimensions of OSSD. In the second phase, this model was interval dated with external constructs Product Development Time (PDT) and Customer Satisfaction (CS) using a fresh test sample of 300 organizations. A very satisfying internal consistency and strong positive connection between each of the two dimensions difficulty and concerned performance outcomes are established, the total model variance being explained with 51% as noted on a PDT scale. This model draws the scope and construct validity, let alone the reliability of the instrument-that could measure OSSD. The model does not cast a very broad category to the generic innovation scale; whereas, this kind of measure is exclusively to do with "open-source" developments such as objectives with distribution of activities, plan-to-make a development, and verily a community-implemented quality assurance. Thus, the present scale validation becomes significant being the very first in the setup of the OSSD universe in India for the purpose of offering a solid guide to researchers, policymakers, and practitioners on evaluating and supplementing OSSD performance within emerging market settings
