Forrester's recent network and telecom survey of buyers identified a troubling trend: Some early adopters of unified communications (UC) solutions are not deriving the benefits they expected for key stakeholders within the business. Unified communications adoption is nearing a turning point, but adoption won't be sustainable if buyers don't see measurable results. Vendors must be crisp and ensure business value is present in collateral, establish clear linkages to industry case studies, and — in these stark economic times — provide a tangible return on investment (ROI) model that can provide payback, usually within 12 months.
