Advice 1: How to calculate labor hours

Effective work of any enterprise is impossible without planning. The plan of production or service, you need to know of such magnitude as the laborhour. At its core standardhour is a temporary standard for the performance of a particular production activities and reflects its complexity and, ultimately, has a direct impact on the cost of products or services. You can calculate it yourself.
How to calculate labor hours
Instruction
1
The total number of working hours is equal to the number of employees engaged in production, multiplied by the time that was spent on the production of a product of common efforts of these workers. It is really spent the hoursof am, which could serve as a standard. This is because in the production process every minute working time are not used with equal intensity.
2
Note that the hourt of time was used for rest breaks. Suppose you expect normo-hour, s for a production unit, which employs 10 people within 1 working week with a total duration of 40 hours. During the day they do two breaks of 10 minutes each. Thus, the total time that 10 workers had spent breaks during the five-day working week will be:
(10 min. * 2 * 5days) * 10 people = 1000 minutes or 16.7 hourss.
Therefore considering the time spent at the break, the total time for manufacture of the product were as follows:
10 * 40 hours – 16,7 = 383 hour.
3
So your calculations were more accurate, they should consider the days of temporary disability and absenteeism. This figure may vary depending on the time of year and public holidays falling at different times. As practice shows, the average for the year is 4%. Check the estimated values using this parameter, the number of wasted man-hours will be equal to:
383 – (383 * 0,04) = 367,7 man-hours.
4
This figure is too theoretical and needs to be clarified because productivity for one business day are also different. At the beginning of the work day need time to prepare for work, and in the end to go home. In addition, hourt of time can be lost due to lack of materials, tool breakage. Such losses usually do not represent more than 7% of the time. With this in mind, the potential number of man-hours will be equal to:
367,7 — (0,07 * 367,7) = 367,7 — 27,7 = 342 man-hourand practically available.
5
Now, calculate the laborhours. If the productivity of this working group is not higher than normal and equal to 100%, the number of normo-hours will be equal to 342, if the efficiency of labor in this group is higher and equal to 110%, then your order will be 342 * 1,10 = of 376.2 laborhour.
6
For these calculations you can see that if the group charging the purchase order, the estimated execution time of which 400 hourss, the workers will not have time to run it for a week. Keep this in mind and solve the problem by increasing the number of workers or transfer hourti of the order to another unit.

Advice 2 : How to determine the hour norm

The efficiency of each enterprise depends on the planning. If you need to plan the production or service, you need to know what is labor hour. This time standard, reflecting the complexity of an operation on the production. It is also worth noting that it directly affects the cost of products and services. Calculate labor hours by yourself.
How to determine the hour norm
Instruction
1
To calculate the total number of hours worked, multiply the number of people employed at the enterprise employees at the time that was spent on the production of the considered product their efforts. It is unlikely that it will be actually expended hours could be the norm. The reason is that every minutesand working time in the production process is used with varying degrees of intensity.
2
Don't forget about lunch breaks, rest. For example, the company consisted of 10 workers. Total working hours per week – 40 hours. The day they make two ten-minute break. The total time that was spent 10 workers on breaks: (10 minute * 2 * 5 days) * 10 workers = 1000 minutes, the clock will be equal to 16.7.
3
We can now calculate the total time spent on production, taking into account rest breaks: 40 hours * 10 – 16.7 hours = 383 man-hours.
4
For more accurate measurements, consider the truancy and days of temporary disability of workers. It all depends on the number of holidays that fall on a particular time of the year, and not only from this. If we take the average value of this indicator for the year, it equals 4%. Now make a recalculation of labor hours based on this indicator: 383 – (0,04 * 383) = 367,7 man-hours.
5
Although this, in turn, would also be helpful to clarify, because the productivity, if you take into account working day also varies. So, at the beginning workers spend time preparing to work, and closer to the end of the day many have off work and going home. And the tool, for example, can come into disrepair, which will also influence your workflow. Of course, to predict what will break when and how long each worker spends time preparing to work and home fees, it is impossible, but on average, these losses amount to 7% of the working time and more.
6
Considering the above, we obtain a formula: 367,7 – (0,07 * 367,7) = 342 man-hours actually available to the workers.
7
Calculate labor hours. If the efficiency of labor before the working group is 100%, without exceeding the norm, the number of labor hours we will be 342. But if the efficiency of labor will be equal to, say, 110%, at the disposal of the workers will already 342 * 1,10 = of 376.2 standard hour.
8
Judging from the above information, you can see that if a group of workers in 10 people charging the order with an estimated lead time of 400 hours, they will do it during the work week. Consider this to predict the failure to implement the works in time. You can increase the number of workers who will be involved in the order, or send part of the order to a different division.
