It adopts Bahman Group Corp of the automobile industry in Iran as a case study. This paper aims to examine the effect of internal marketing (IM) on service innovation (SI) by the mediation effect of motivation (MO). It develops a theoretical hierarchical multi-component model and analyses through a two-step approach of higher-order model by using PLS on 171 clean data. This research uses a survey method to collect data from the employees of Bahman Group Corp. The results indicate that motivation (MO) has a partial mediation effect between internal marketing (IM) and service innovation (SI).

Moreover, this research highlights to the service-based organisation to pay more attention to enhance internal marketing dimensions, especially in terms of service innovation to improve competitiveness.
