This white paper discusses the four stages of a unified communications (UC) journey: 1) individual productivity, 2) workgroup productivity, 3) communications-enabled business processes, and 4) enterprise transformation. It notes that UC can significantly improve productivity, reduce costs, and transform business processes and customer engagement. The paper provides examples of cost savings and productivity gains achieved at each stage. It argues that companies should view UC as an evolutionary journey that delivers ongoing benefits, and that now is the time to begin planning their UC strategy and implementation.
