One advantage of this is the fact that the index does not depend on who collected the data or when it was collected. Evaluation and measurement Measurement is the methodology of establishing the amount of wok involved in a work function. Evaluation is using measurements that are not strictly quantitative. Efficiency Efficiency as a concept assumes an ability to identify a change in the productivity ratio. Managers want to compare with their competitors and assess the possible scope on productivity improvement. Efficiency gathers this productivity factor into account and compares it to some known potential. In it, direct adjustments for quality are excluded as well as raw materials. This is because the result is knowledge. Here, productivity is calculated using simple O/I algorithms. It presents eight levels of work units, from the lowest-motion up to highest-results-achieved because of outputs. Sassone (1991) The technique used by Sassone is simple to implement. If production costs do not exceed productivity increase, there is a possibility of a price fall or stability. It is also conducive to lower inflation. In other countries, productivity has grown. In rich countries, GDP soared mainly because of the increase in productivity. The poorest countries in the world are typically with a low productivity increase. These services can combine voice, email, IM, fax, collaboration, conferencing, file sharing and more to have completely integrated communication. Goals Unified communications sets to increase the efficiency of business communications. Information that can be received in various forms can now be responded to with more immediacy than information passed through only one form. Worker enhancement programs are built on ways on how to motivate workers to optimize productivity. Some organizations offer their workers sports and recreational activities, fitness and leisure activities and some family-oriented programs. This comprehensive approach in enhancing worker performance may capitalize on quality measures like value, TQM (total quality management), quality circles, innovations and performance standards (profitability, efficiency, customer satisfaction, on-time delivery) and carries a wide range of personal and team rewards and incentives.
