Zions Bancorporation (Zions) of Salt Lake City, UT, operates more than 480 full-service banking offices in Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah and Washington. This geographically dispersed company focuses on providing truly local management teams with community identities, supported by ferociously efficient IT services based at the head office.

Business need
As Zions Bancorporation thrived and grew, sheer volume of work threatened to overwhelm the company’s back-office, potentially damaging the bank’s reputation for outstanding customer service.

Accelerated key business processes up to 33 percent by migrating core banking applications to an IBM® zEnterprise® BC12, and readied the company for web and mobile apps in its next expansion phase.

Faster back-office processes enable the bank to deliver excellent front-line customer service, enhance its reputation and grow the business without the need to add technicians or raise operating costs.
