Incremental innovations are process base innovations. These innovations happen while developing or processing of units due by the effect of Philosophy of Kaizen (always looking for improvement) such as reduce waste, scraps etc. Therefore, small series of step by step innovations mark the incremental innovations. Eg – 2G – 3G – 4G – 5G.
This section of innovation contributes large numbers of innovation. Though, most of these innovations are not visible in public because they are innovated under the boundary such as those innovations taking places inside the company. This is why, incremental innovations are still debatable.
While incremental innovations are going on, there comes many breakthrough innovations and again these breakthrough innovations would fall under incremental innovation. Because incremental innovations make suitable use of these breakthrough innovations. Otherwise they will end up at laboratories or experimental spots.
