By integrating big data analytics, companies can improve their strategies. Big data analytics can effectively help operations improve efficiency. This helps to increase the company’s profits along with performance. Forming the base of Resource Based View in developing Dynamic Capabilities the theory will subsequently extend to form the shape of Service Analytics Capabilities and its impact on firm performance, however this research has examined the potential mediating role of talent capability in reshaping SAC to improve firm performance. In addition to it, the Moderating role of Top Management Attitude (toward adoption of analytics) between BDA and Firm Performance has been evaluated. The model is tested on data analysts working at Telecom sectors of Telenor, Ufone and Mobilink (located at the headquarters of Islamabad in Pakistan) . A questioner was recorded from 100 respondents and the data was analyzed using PLS smart software. The technique is applied to find the relationship between independent and dependent variables with the help of moderating and mediating effect. Our findings suggest that Dynamic Talent Capability mediate the role of Dynamic Information and Dynamic Technology capability with Firm Performance in Big Data Analysis (BDA) and Top Management Attitude toward adoption of analytics have significant impact to moderate the association between Service Analytics Capability and Firm Performance in BDA Environment. On the other hand dynamic information, dynamic talent and dynamic technology capability have an insufficient effect on firm performance. Supervisor:- Dr. Nadeem Ahmed Khan
