Responsibility for running a mainframe does not always lie with the IT department, according to a study of large IBM mainframe users by Market Clarity.
Once the preserve of datacentre managers, control of the mainframe could lie with a business unit or an outsourcing specialist.
Overall responsibility for the mainframe within business divisions was found to reside with directors, head office, planning personnel, enterprise managers, and strategy managers.
Within IT, control resides with central data departments, IT directors, architecture and design experts, mainframe teams and internal technical services.
Of the 21 organisations surveyed, responsibility for mainframe integration budgets was split equally between business units, central IT, or a combination of the two.
Stephen Martin, managing director of Market Clarity, said, "In the past the mainframe would have been owned by finance people. Now mainframes are acting as vast repositories for data, things have changed.
"If you are a finance organisation, the finance department may still own it. If the company believes IT is a key part of its business, it is likely to be an IT person who manages the mainframe. In companies where marketing and sales lead, it will be a combination of the two."
Compuware enterprise solutions director Ian Clarke said, "The more you see your mainframe as core to your business, the more it moves into the network and architecture side of your business."
