Teamwork, for competitive advantage, involving techno-socio-cultural aspects of organizations for engineering developments, is gaining importance rather rapidly due to advent of globalization. The purpose of this study is to identify the importance of teamwork culture for new product develop-ment (NPD) success through enriching the NPD team’s capability in Indian manufacturing industries. It accumulates the teamwork culture dynamics and practices, their interrelationships and their combined impact on NPD team’s capability in terms of technological developments for NPD success. This practical analysis collects primary data from 263 design and development experts from Indian engineering manufacturing companies. Structural equation modeling (SEM) approach is applied to investigate the interrelationship among associated variables of teamwork culture and NPD team’s capability for NPD success. Concurrent engineering team (CET), communication infrastruc-ture (CI), system integration (SI) and result orientation (RO) have been recognized as allied factors of teamwork culture. Successful adoption of associated variables ensures NPD success through influencing NPD team’s capability which in turn articulated by technological developments. The realization of combined impact of teamwork and its allied variables escalates technological developments which in turn enriches NPD team’s capability assuring organizational success. The result indicates that both CI and SI support CET for accelerating NPD team’s capability through technological developments. Besides, CET motivates innovation orientation most precisely referred as RO for escalating NPD team’s capability through technological developments for innovation.
