There is not one way to start moving toward organizational excellence. Here is one approach to getting started.
Learn to look at your organization with new eyes. Where is the activity that does not add value to the product? The amount of activity that does not add value can be thousands of times of the amount of activity that does add value. Figure out how to eliminate activity that does not add value.
For example, transportation of material does not add value. Of course, product has to be moved from one operation to the next, but often we increase transportation by having unnecessary space between any two operations. Because we have the space, we don't move each piece to the next step immediately, we allow the product-in-process to accumulate in containers, to the point where it can no longer be moved by hand. Now we need a forklift to come and move the container.
