# How to determine sample volume

The concept of development, most often, is used as one of labor productivity indicators. The labor productivity characterizes degree of efficiency of work, its ability to make in unit of time a certain quantity of goods and services and also the amount of time spent on production of a unit of production.

## Instruction

1. Among performance indicators the norm and level of development are the most important. How to determine development level? For a start determine performance standard by a formula: Nv = Tr*ch/TnGde Tr - duration of the period for which the performance standard is established (in hours, minutes); h - the number of the workers who are taking part in work performance; Ton - norm of time for this work or one product (in man-hours).

2. The performance standard depending on a type of goods, works and services can be expressed in pieces, units of length, area, volume, weight, etc.

3. Specialists in rationing of work allocate several types of development: - average hour development – the production volume relation for the period to number of the hours worked all workers for this period; - average day development - the production volume relation for the period to number of the man-days worked all workers for this period; - average monthly development - the production volume relation for the period to the average number of workers in a month; - average annual development - the production volume relation for the period to the average number of workers in a year.

4. Having defined performance standard, find the development level as the relation of actually made goods, works or services to norm. Let's review an example: let's assume, the performance standard is 10 pieces of products an hour, the worker produced 9 pieces. Level of development is 90%. If the worker produced 11 pieces, respectively, the performance standard is 110%.
