By now you've probably heard the phrase "enterprise architect." People in the know are hard-pressed to describe exactly what an enterprise architect is, but they say one thing is clear: the relatively new job title represents a growing and lucrative field for IT pros. An enterprise architect is sort of like a city planner, says Allen Brown, president and CEO of the Open Group, a standards organization. Rather than tinkering with individual pieces of hardware and software, the architect attempts to ensure proper integration of all the infrastructure and applications throughout an organization, Brown says. A global bank is likely to have 400 architects, but the profession is still in its infancy, he says.
