redefining Work in the Lean Manufacturing Process
What does it mean when someone says that work creates electricity? The definition given in physics is work is energy transfer from a source to an end or by some kind of physical displacement from some state to another. In its most simple form, it can be simply represented as the resultant of a force and displacement. If we take the common electrical example, you would find that if you cut a light wire, the voltage would change. The amount of the voltage would depend on the length of the wire. The longer the wire, the smaller the voltage change, and the harder it would be for the wire to get back to its original state.
Another example would be the movement of water through a pipe. Water molecules can easily be replaced by any other kind of molecule, and you might assume that all the work done by the pipe’s flow would be equal to the total force of water molecules. To see how this works you would need to know how many joules are required to go from one point to another. And since the total force of the water flow is equal to the total joules, we can conclude that there is work done to produce the displaced location.
Now, since your average household electric meter only measures the voltage produced, you won’t get a true picture of how much work is being done. The only way to do this is to use a kilo watt meter that measures the energy produced, and which also measures the voltage. You would then divide the actual work done by the total energy produced, to get the kilo watt meter’s level of efficiency. This would mean that if you measured your home’s electricity usage, and found that most of it was for just the production of energy, then you would understand why the meter says that there is little work being done. The fact that there is little work done means that the kilo watt meter is not giving you a true depiction of how much actual work is being done.
To get a more accurate reading, you need to measure the work that is being done with the displacement device. The method for measuring work using displacement is known as the dynamic displacement measurement. To perform this type of measurement, you attach a spring-like device on a part of the object that is moving, such as a leaf falling on a table. Then, you will apply a constant force on the object, which will make it stick fast to the surface it is attached to. You can calculate the amount of work done by connecting the output force to the spring’s displacement. This can be compared to the level of your household’s electric usage to get a good idea of how much electric power is being used in your house.
The second factor that must be measured is the value creation factor. Since the main goal of measuring efficiency is value creation, the best way to do this is to calculate the number of hours or work hours per dollar. You have to compare how many hours are actually used to the number of hours that are supposedly spent for work purposes. For example, if you are doing an estimate for new cabinets, you should include the cost of labor hours in the value creation calculation. This will help you determine how many new cabinets can be created per dollar if your company creates them 20 times as many times as the amount of labor hours that are being used in the process.
Finally, you should make sure that the value creation and redefining work are both accurate. In measuring the value creation, you should focus on all the factors that can contribute to the value creation, such as the quality of the raw materials and the cost of the labor in doing the work. If the value creation is inaccurate, the economy will suffer because the money spent on creating new goods and services will not be worth the investment. In redefining work, you should focus on the routine tasks that have no effect on the economy in general. However, it should still be included in the evaluation so that companies will know if their business can benefit from these routines or not.
