Objectives of the Research Paper The objective of this research is to demonstrate how Mashreq Bank has benefited from the adoption and implementation of Microsoft windows based platform in its core banking operations. The windows platform is becoming increasingly attractive to large banks. It is used to support their primary banking services that include ATM, Internet banking in addition to branch and call center operations. Overview and background for Mashreq Bank Mashreq bank is the largest private sector bank operating in the United Arab Emirates (UAE). The company has approximately USD $14 billion worth of assets. The bank offers financial services through its 60 branches in UAE and Qatar. Mashreq is regarded as a pioneer in banking in the UAE fully dedicated to offering full financial services both to its commercial and retail banking customers. It was the pioneer bank in the region to issue credit, and debit cards, implement a call center, 24-7 access to automated teller machine, and link its branches to a centralized online database. Before shifting to the windows based platform the company had significant performance challenges in meeting service levels on the Unisys (NCR) mainframe processor.
