Information-technology expert Charles Nault, founder and chairman of Atrion Networking Corp., of Warwick, says in his new book, Risk-Free Technology: How Small to Medium Businesses Can Stem Huge Losses From Poorly Performing IT Systems, that hiring the right information-technology manager is crucial for business success. Unfortunately, in a typical company, the IT department “doesn’t understand your business, thinks it is doing a better job than everyone else in your company thinks it is doing, does not like to communicate with you and when it does it tends to talk in language you can’t understand — and then tends to make you feel inferior for not understanding,” he writes. Look for an IT manager who has a passionate desire and ability to understand your business, your strategy and your value to your customers; an understanding of the economic engine that drives the profitability of your business; humility; integrity; vision; and an ability to communicate effectively both verbally and in writing, he advises.
