The client

Our client is a hospital and medical research facility with a global reputation for outstanding patient care. The cornerstone of our client’s IT infrastructure is its mainframe, which supports a wide range of mission-critical applications including patient registration, admission and scheduling, billing and payroll.

The obstacles faced

Each year, millions of people from around the globe journey to America’s heartland in search of a medical miracle. Parents with children, families with loved ones make their quest to this world-renowned hospital and research facility, which focuses all of its resources on its noble mission: healing the broken, finding the cure, saving lives.

Many of this hospital’s mission-critical IT applications are run on its mainframe. When a staffing shortage for this essential business platform jeopardized the seamless delivery of key patient services, the hospital turned to an outside expert to manage this crucial component of its infrastructure.

The journey

The hospital made the strategic decision to transition mainframe operations to an outside expert, selecting Ensono because of its strong team of mainframe experts, competitive pricing and ability to address challenges beyond the engagement’s initial scope. Due to the short timeframe for moving operations, the medical center opted for a remote management solution.

The client-Ensono team fully transitioned operations in just 60 days. With Ensono managing the mainframe environment, the hospital has been able to allocate IT staff to a number of other key initiatives.

The outcomes achieved

Ensono has enabled the hospital to:

  • Continue delivering uninterrupted patient services including registration and admission, scheduling and billing
  • Optimize the mainframe environment, enabling it to add applications, including payroll for one-third of the hospital’s 64,000 employees that had been on a different HR system
  • Expand capacity, making room for a 15 percent increase in transactions with no hike in costs
  • Save $300,000 annually by identifying software no longer in use, enabling the hospital to cancel contracts and not renew licenses
  • Augment its mainframe security team

As the healthcare industry undergoes sweeping changes, Ensono and the medical center continue to identify new opportunities to optimize mainframe operations. The hospital’s IT team draws on Ensono’s expertise to improve staff and systems performance beyond mainframes, including security oversight. “Ensono makes us feel like we’re their only client,” says the hospital’s director of IT.

The organization is planning its next major step —migrating its mainframe operations to Ensono’s data centers. Moreover, Ensono is serving as an advisor as the hospital considers shifting its critical business applications from mainframes to other platforms. As we look to the future and our evolving role, we continue to help our client operate for today and optimize for tomorrow.

“Ensono makes us feel like we’re their only client.”
