Abstract

Productivity in making and moving things hasincreased at an annual rate of 3 to 4 percent compounded for the last 125 years -or a 45-fold expansion in overall productivity in the devel-oped countries. However, there has not been such a big improvement in knowledge worker's productivity. A knowledge worker is a profes-sional who applies ideas, concepts, and informa-tion to work rather than manual skills or brawn [4]. In some developed countries, knowledge workers represent approximately 80% of all employees and perform key roles in economic activities in an enterprise. Therefore, the produc-tivity of the newly dominant groups in the work force, i.e., knowledge workers, will be the big-gest and toughest challenge facing managers in the developed countries for decades to come. Also, some analysts forecast that the stagnation of productivity of knowledge workers will emerge as one of the obstacles to maintain an appropriate level of growth for the twenty first century
