In recent years, Customer Relationship Management (CRM) has become a topic of major importance. However, the mobile medium as an element of CRM (i.e., mobile CRM) is rarely taken into consideration. This paper attempts to investigate the behavioural intention of sales executives of pharmaceutical sector to adopt this mobile technology. To examine this, an extended technology acceptance model (TAM) is used which has now become one of the most widely used models in information technology. This extended research model is tested against data obtained from 158 sales executives from top pharmaceutical companies covering the Odisha state. Correlation analysis, and multiple regression analysis were used to analyze these data. Our findings indicated that behavioural intention was sufficiently explained by perceived usefulness, perceived ease of use, perceived information quality and perceived system quality. Perceived Job Relevance also emerged as a strong predictor of behavioural intention to explain the adoption of mobile CRM. Contrary to our hypothesis, Perceived Reach ability did not exert sufficient effect on behavioural intention.
