The productivity frontier is constantly shifting outward as new technologies and management approached are developed and as new inputs become available. Laptop computers, mobile communications, the internet, and software such as lotus notes, for example, have redefined the productivity frontier for sales-force operations and created rich possibilities for linking sales with activities as order processing and after-sales support. Similarly, lean production, which involves a family of activities, has allowed substantial improvements in manufacturing productivity and asset utilization.
For at least the past decade, managers have been preoccupied with improving operational effectiveness. Through programs such as TQM, time-based competition, and benchmarking, they have changed how they perform activities in order to eliminate inefficiencies, improve customer satisfaction, and achieve best practice. Hoping to keep up with shifts in the productivity frontier, managers have embraced continuous improvement, empowerment, change management, and the so-called learning organization. The popularity of outsourcing and the virtual corporation reflect the growing recognition that it is difficult to perform all activities as productively as specialists.
