Minimization Vs Elimination

Is there a deference between minimization and elimination. For an example does minimization of waste sound defer from the elimination of waste. If your answer is yes, then you are correct. These two terms have very deferent meanings.

We will take waste as an example. Most of the industries talk about minimization of wastes. They will work towards this goal and will end up in making no or very little progress. This is because of the wrong thinking. When you think about minimizing of wastes, then you do a fundamental error. What is that? Let me explain

When you think about minimizing wastes, you accept two things. First you accept the fact that you have wastes in your system. This is fine. Your understanding is good. Secondly, you accept that your system will continue to have wastes. This is because even you minimize, the system will still have wastes in your system. What you have done is only reducing the quantity of wastes produced in the system. This is not good. You work in a system where there are wastes. You are also expecting to create a system which will have wastes, but in a lesser quantity.

Lean manufacturing conceptually differ here from the traditional manufacturing. Lean manufacturing focus on eliminating the wastes from the system. Lean manufacturing first identifies the wastes. Then the causes for these wastes are analyzed. Then lean manufacturing techniques are applied to remove the causes for these wastes. The result will be a system where there are no wastes.

Treating the cause will cure the problem permanently. Treating the symptom will only give temporary solutions.
