Case Study: UBS achieves scalable, high-volume mainframe software configuration control with Serena Software's ChangeMan ZMF

UBS Banks On Serena For Software Configuration Management

UBS, a global leader in wealth management and investment banking, needed to migrate core banking applications from Unisys to IBM zSeries and handle a massive, ongoing volume of software change while meeting strict audit and regulatory requirements. The IT team required a scalable, flexible configuration management solution to control the application lifecycle, enforce development processes, and improve confidence in testing across hundreds of thousands of daily users.

UBS implemented Serena ChangeMan ZMF (with Serena TeamTrack for process automation) to manage lifecycle handoffs and track changes. The solution streamlined development, reduced application errors, and supported unprecedented volumes—about 485,000 component builds submitted, 190,000 package promotions processed, and 800,000 component versions installed annually—used by over 2,000 developers across seven global locations.
