Develop a timeline that identifies the approximate times at which the various stages of the Change Management Continuum Model should occur for the implementation of a major enterprise system. Assume that the project will last 18 months and has these key milestones:
• Systems definition complete at 3 months
• System design complete at 7 months
• System construction complete at 12 months
• System testing complete at 16 months
• System cutover starts at 18 months
