This online assessment tool designed specifically for organizations seeking to improve their Green IT capabilities, performance and ROI. The tool, which utilizes Aberdeen's primary research in Green IT and Sustainability, helps companies of all sizes identify potential areas for improvement, including server and data center virtualization, energy efficiency, end-user collaboration, and recommends steps that companies should take to address these capabilities and achieve ROI from their Green IT investments. The tool automatically compares companies of a similar size. Large companies are compared with other large companies while midsize firms are compared with companies that have about the same number of employees. The assessment helps companies determine their Green IT posture by benchmarking against Best-in-Class organizations, as identified through Aberdeen's PACE™ (Pressures, Actions, Capabilities & Enablers) research model.
