Overseeing IT at a small or midsize business is a lot more challenging than overseeing IT at a Fortune 1,000 firm. Here are some secrets to success:1. Look outside the enterprise to outsourcing providers and vendors for help with complicated projects.2. Don’t be afraid to get your feet wet and jump in to handle “emergency” situations.3. Work hard at managing up and maintaining good communications with top executives, whether or not you report to them.4. Recruit and retain staffers with an attractive mix of flexibility and independent projects.5. Make a case for IT investments based on how they will help your company comply with federal regulations such as the Sarbanes-Oxley Act.
