Professional IT ... Roles of IT Professionals

1.  ROLES OF IT
PROFESSIONAL
As IT professionals we live in exciting times. The IT profession is coming of age and the role of
the IT professional is changing rapidly. The traditional IT Department, as a support function
dedicated to providing technical solutions to problems defined by ‘the business’, is set to
disappear. The reality today is that IT doesn’t just support business, it powers business and the
future for the IT profession is all about the development of business-focused professionals with a
much wider range of skills and capabilities than in the past. Information technology can, and in
many instances does, deliver very substantial business and social benefits. It enables
organizations to make dramatic leaps in productivity and governments to deliver greatly
enhanced service levels that their citizens now expect. But successful IT enabled business change
often remains elusive. If we are to realize the full potential of IT the function must move from
being viewed as a technical solution provider to be seen as a full transformation partner.
IT teams are responsible for the computers, networks, and software applications that manage a
company’s operations, track financial transactions, and enable people to communicate and
collaborate throughout the company. Without a smooth flow of information through a company’s
IT systems, operations would not be efficient or even possible in some cases.
