To serve customers well, eBusiness executives need to hire the best technology partners: those that innovate well but have staying power as markets evolve. We studied 40 instances of the Forrester Wave™ to find patterns around the evolution of technology markets and the technology vendors within them. In this report, we explain the three market transitions all markets go through — pivot, havoc, and stability — and relate them to Forrester's TechRadar™ model. We provide advice for technology buyers navigating the predictable disruption and consolidation that every market experiences.
