The workers followed the old routine of bringing in the materials in the first floor, doing the sub-assembly at the second floor and the final assembly at the top floor. Over the years, the machines assembled got bigger and bigger and they were difficult to bring down from the top floor. Somebody finally suggested reversing everything: bring the materials to the top floor, do the sub-assembly at the second floor and the final assembly in the first floor. Their inclusion into the calculations makes them more difficult, makes them fuzzy, and dilutes the clarity of the measurements. Productivity Again, strictly speaking, measurements are numerical indexes. Productivity measurement is one. It is expected that the same inputs should produce the same outputs a number factor. Mobile phones Today, mobile phones are now capable of playing a big role in unified communications because you can use them to retrieve calls, exchange information, and being able to access the web and IM programs. Google and other web services With Google Voice, it is easy to archive and retrieve information from voice mail messages. Getting started Although self-assessment, for other people, can be a good start in building a positive attitude and outlook in life, this might not be applicable to all people especially to those who prefer to do things on their own. If you are one of these people who would rather do things on his or her own, then now is the time to realize how big self-assessment can contribute to your being productive. 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. The third system is designed to evaluate various productivity measures and decide which are the most important. It also allows the combining of dissimilar productivity measures. Other techniques There were other researchers who use the group technique. Bernard (1986) used project teams and stressed maximizing diversity with the premise that managers cannot be assumed to know what really is going on.
