This document provides a four-step process for creating a business plan and roadmap for transforming a contact center to an IP/SIP environment. The four steps are: 1) Assess the current state of people, processes and technology; 2) Determine the ideal future state based on business strategies; 3) Analyze gaps between the current and ideal states; 4) Build a transformation roadmap that provides a phased plan and measurable goals to move from the current to ideal state. Developing an ROI-based business case is also important to obtain approval and funding for the transformation project.
