Re-engineering involves analyzing an entire organization to streamline or remove unnecessary processes to improve efficiency and customer satisfaction. Arthur Yeung provided a six-step model for HR reengineering that includes critically analyzing current conditions, creating models of current and desired future processes, defining target processes for reengineering, implementing and propagating changes, and measuring impacts. HR plays a key role in successful reengineering by implementing new team structures, empowering jobs, shifting from training to education, and focusing on results over activities.
