Dynamics it is accepted to call change of some indicator in time. The labor productivity can be calculated for the certain worker, the enterprise, the industry or economy in general. To calculate dynamics, you need to know several indicators calculated through certain periods.
It is required to you
- - labor productivity indicators;
- - calculator.
Instruction
1. Calculate labor productivity of the certain worker on a formula P=K/t where P — labor productivity, To — quantity of the developed products made by this worker, and t – the spent time. If the worker works not continuously, then in a denominator of fraction there will be not all duration of the working day, and the sum of intervals of time which the worker spends on production of details. That is the formula will look so P=K / ∑ t. The labor productivity on the shop or the enterprise in general is in the same way calculated.
2. Remove several such indicators at regular intervals. For example, it is possible to trace as the labor productivity of the worker within week or month changes. Make the table. For one worker it will consist of only two lines. The quantity of columns is equal to the number of measurements. In the first line write dates of calculations, to the second — the labor productivity indicators corresponding to these dates. When determining time, idle times and other breaks should not be considered.
3. Dynamics of labor productivity can be presented also in the schedule form. On abscissa axis divide into equal pieces. Designate dates. Postpone the indicators corresponding to each date for ordinate axes. Connect points the broken line.
4. At large enterprises the monthly, quarter or annual development, that is labor productivity of all collective for a certain period is usually calculated. It is calculated by the same formula, only in numerator of fraction costs total number of the products developed by the enterprise for this period, and in a denominator — total number of working hours. Indicators are entered in the table or are noted on graphics.
5. Dynamics of labor productivity can be expressed and as a percentage. Take the first period of time when you took measurements for 100%. Make a proportion of a type of K1/100= of K2/x. Find unknown size x, having increased K2 by 100 and having divided the received work into K1, that is x = K2*100/K2. The result will be in the form of percent. Find the difference between it and an initial indicator. It will also be dynamics of labor productivity expressed as a percentage for one period. Carry out similar calculations also for other periods.
