While the market orientation (MO) is a significant predictor of new product development (NPD) performance in the previous studies, research reveals that adopting the MO is insufficient without a deeper grasp of other determinants. The study model is based on the resource-based view (RBV) to investigate the MO-NPD performance relationship through mediating marketing technical integration (MTI) in the Egyptian food industry. Primary data were acquired via a self-administered questionnaire from 243 executive managers of 74 food manufacturing companies in Egypt. The gathered data were analyzed using the SEM approach. The findings indicate that MO and MTI are positively associated with NPD performance and that MTI mediates the MO-NPD performance. Furthermore, the findings suggest that larger companies may be better at controlling NPD performance. In addition, environmental dynamism raises NPD performance.
