Fill in skills shortages with mainframe outsourcing

A qualified personnel shortage is putting pressure on mainframe deployments.

As mainframe usage declines, the pool of qualified IT workers who program and service big iron systems is aging and declining in size as well. Businesses are finding it harder to hire and retain staff with mainframe skills. This hinders every aspect of operation from timely software updates to effective hardware service and troubleshooting, to integrating the mainframe with outside systems and applications, along with security, storage anddisaster recovery.

Four strategies mitigate mainframe support problems.

This is a difficult goal because applications and data stores will need to be revised, converted or reverse-engineered to accommodate the new platforms. The real concern is cost; is the cost of such migration less than the cost of continuing reliance on the mainframe and qualified staffing?

A second alternative is mainframe outsourcing — essentially divesting the in-house system and staff, and allowing another business to run those workloads for you. You must rely on their business competence and IT expertise. Outsourcing is typically considered a risky alternative because mainframes invariably host mission-critical tasks, and disruptions to the service provider are catastrophic for a business that outsources. And there is still migration work required for the outside provider to host your applications.

A third alternative is filling any mainframe skills gap with outside consultants or contract employees. Temporary employees are usually less-than-ideal alternatives to on-staff mainframe support because of the time it takes to learn your applications and systems. Any knowhow acquired along the way — and funded by your business — will disappear when the engagement ends. Contractors can be an effective stopgap measure for relatively straightforward tasks where learning curves are small.

The fourth strategy is developing and expanding in-house mainframe training initiatives and encouraging retention of experts. Try mentoring, computer-based training, vendor-specific training in mainframe systems and management tools, attendance at mainframe conferences and other tactics.

None of these alternatives immediately resolve mainframe knowledge shortfalls. In many cases, IT shops apply app migration, outsourcing, contracting and training in varying combinations to address urgent needs while fostering long-term skill building. For example, a company outsources some of the most easily migrated workloads while engaging a mainframe contractor to handle routine tasks. This frees the retiring in-house mainframe support staff to spend time training designated employees the skills to take over mainframe management for another 10, 20 or 50 years.
