There can be a tendency to see invention and innovation as one and the same.
Inventions are new technologies that change the world - the satellite, the motorcar, television, the plough. Innovation can be world-changing too, if it’s transforming business models or offering novel services on the back of new technology - think Uber (GPS) or Facebook (the internet).
Most innovation is much more incremental though, building or improving on past forms or ideas that touch our daily lives in a much more frequent and personal ways. The key, therefore, to successful incremental innovation is making sure that those small changes are the right ones.
