An innovative initiative may draw on something existing and endeavour to explore all the possibilities for its improvement. In this respect, it is always possible to do better, faster, cheaper, stronger, easier to maintain or simply differently. Innovation can be in the continuity of a product or process: the improvement is incremental and concerns the profit margin; or it may introduce a breakthrough, in which case it is a radical innovation. From the point of view of the individual or the organisation, innovation can be the result of an initiative or be perceived as a necessity, an obligation.
