For many IT vendors, sales targets continue to increase every year at rates upward of 15% annually. In contrast, worldwide IT spending in the large enterprise segment is forecast to grow only by 4.2% in 2018. To achieve these numbers, IT vendors need to be better informed and sell smarter. Selling smarter means having a more intimate understanding of buyers, including their unique business challenges and objectives and, in particular, better market analytics focused on their overall IT purchasing behavior and priorities. IDC's Worldwide IT Wallet service provides an analysis of the regional IT spending strategies and budgets for more than 2,700 of the world's largest companies. The research is crafted to arm sales and marketing organizations with the specific information they need to incorporate into a smart selling strategy.
