Sources and measures of innovation

There are two main sources of innovation. The traditionally recognized source is manufacturer innovation. This is where an agent (person or business) innovates in order to sell the innovation. The other source of innovation, only now becoming widely recognized, is end-user innovation. This is where an agent (person or company) develops an innovation for their own (personal or in-house) use because existing products do not meet their needs. Eric von Hippel has identified end-user innovation as, by far, the most important and critical in his classic book on the subject, Sources of Innovation.[1]

Innovation by businesses is achieved in many ways, with much attention now given to formal research and development for "breakthrough innovations." But innovations may be developed by less formal on-the-job modifications of practice, through exchange and combination of professional experience and by many other routes. The more radical and revolutionary innovations tend to emerge from R&D, while more incremental innovations may emerge from practice - but there are many exceptions to each of these trends.

Regarding user innovation, rarely user innovators may become entrepreneurs, selling their product, or more often they may choose to trade their innovation in exchange for other innovations. Nowadays, they may also choose to freely reveal their innovations, using methods like open source. In such networks of innovation the creativity of the users or communities of users can further develop technologies and their use.

Whether innovation is mainly supply-pushed (based on new technological possibilities) or demand-led (based on social needs and market requirements) has been a hotly debated topic. Similarly, what exactly drives innovation in organizations and economies remains an open question.
