An IT expert has claimed that internal IT support departments are "ineffective" and too expensive.

IT Computer Support of New York said companies could benefit from outsourcing their IT services to another provider as they would have access to professionals who are experts in computer support.

According to the technology specialist, doing so could also lower firms' IT management expenses.

"Companies have cut their IT costs, improved their IT performance and gained competitive advantage through wise selection and use of technology by outsourcingIT support to specialists," the company continued.

It explained that expenses associated with internal IT departments, such as taxes and benefits, workspace, training and equipment, could be cut by using an external provider.

The National Federation of Independent Business says that although the strategy of outsourcing IT departments may result in cost-savings, it can mean that the IT team no longer has intimate knowledge of an organisation.
