How We Save You Money
Mainly by making labor more productive and efficient.
Labor is the highest cost factor in accomplishing the work of sanitizing and cleaning. Labor costs represents between 50% and 75% of the cost of cleaning and sanitizing. If you lower the cost of labor, you lower the cost of the cleaning/sanitizing budget. The labor cost is less because it takes less time to perform the work involved.
We are more productive because we can decrease the amount of work needed to accomplish each task. We do this by using simple Industrial Engineering principles.
First we break each job up into its elementary and most simple task.
Then we quantify the work done by using the scientific formula for work: work equals the force needed to move an object, times the distance through which the force acts. Quantification of the work is extremely important to this process. Once work is quantified, it can be compared, added, subtracted, etc. Since there are two elements, force and distance involved here, we study ways of decreasing both of these elements. The amount that we can decrease these elements determines the amount of work we can take out of the job. The more work we can take out of the job, the more savings we will be able to make.
Second, we increase productivity.
Productivity is the amount of work done in a unit of time. By decreasing the work, it takes less time to do it. Productivity is work divided by time. Productivity = Work/time.
The two main factors that determine productivity are the methods used to get the work done and the and the human factor. Of all the elements involved in productivity, the human factor is the largest, and it is larger than all other elements combined.
Third, we maximize productivity by studying the main elements.
After the human factor, the other main elements in productivity are the methods in using the equipment, tools and chemicals required in doing the work. These are the main elements we study in trying to maximize productivity.
The speed at which a person works is another factor and it is estimated using a scale which is “100% equals normal speed”. If a person is estimated at working 10% faster than normal, then he/she is working at 110%. If the speed is estimate to be 10% less than normal, that person is working at 90%. Most people work between 80% and 110%. If a person is estimated to be working at 110%, he/she will accomplish 10% more work than a person estimated at working at 100% assuming all other factors are the same.
The human factor is more important than all other factors.
Each person is “geared up” for his/her own personal speed. It is best to accept this speed and not try and increase or decrease it. If their speed is too slow, you may not want to hire them, although it must be remembered that the human factor is more important than all other factors.
For example, let’s say you have a good employee, using the most productive methods and equipment, working at 80%, who possesses a good work ethic. Most of the time this person would be far superior to an employee who is also using the most productive methods who does not possess a good a work ethic, working at 100% rate or even 110%.
An example of the calculations of this process would be the difference in someone physically moving a 100 lb. box 10 feet by physically pushing it using a 30lb.force. The calculations would equal this person doing 300 foot pounds of work.
How can some of the work be decreased in this task? The 100 lb. box could be placed on a dolly and rolled 10 feet. Further assume that it only takes 10 pounds of force to push the box on the dolly making the amount of work 100 foot pounds. When calculated, the work required to get the dolly and to put the box on the dolly must be added to the amount of work of pushing the box to the new location. We must also calculate the amount of work necessary to remove the box from the dolly and to replace the dolly.
Simply put, by using the dolly to move the box, two thirds of the moving work has been eliminated. If it took 20 seconds to slide the box 10 feet but after it was put on the dolly, it only took 10 seconds to roll it there, you have doubled the productivity.
If an actual job involved many tasks and you were successful enough to double the productivity on each task, you would cut the time needed to do the job in half. Think how much time you would save. To do the original job would take 8 hours. Now the total job would take only 4 hours. You have saved 50% of the time and therefore 50% of the cost of labor to get this job done.
You might be saying that this is not possible, but stop and think. The back pack vacuum cleaner increased the productivity rate from approximately 3,000 square feet per hour to approximately 10,000 square feet per hour. This is an increase of over 300%!
Work simplification involves much more than this little explanation, but the essence is to study each job and break it up into its elemental task and then study each task, quantify each task, simplify each task, and compare.
