When you look at IT staff compensation by job functions, a few emerging categories top the list: wireless infrastructure, cloud computing, and Web security. (All those have low bases of respondents, so take the numbers with a grain of salt.) But notable are two stalwarts--ERP and enterprise app integration. These have been among the top functions for the decade-plus we've done our survey. While emerging skills around unstructured data analysis rise in importance, they aren't dimming the prospects for conventional software. ERP data is often the most reliable and trusted data companies have, so people who can help companies make sense of that data and share it, quickly, to make good decisions remain in high demand.
