New innovations are constantly in demand.
If you don't improve on your products, someone else will, and you will lose the edge. Product life cycles are shorter than ever, so it is important to be the one to come up with the innovation that will replace your current product. Time is a critical factor. As soon as a product is issued, you should be working on its successor. Someone else will come up with an improvement on your product and take your customer base.
