In many sectors, the disruptive changes now occurring are so major that they have been described as the "Fourth Industrial Revolution". In response, organisations are focusing on innovation - hackathons, innovation labs and design jams are popular. Unfortunately, many innovations do not make it through to implementation.

Many explanations are offered. One is change resistance, but this is oversimplified and usually inaccurate. A more nuanced view is that implementing innovations is much harder than thinking them up in the first place.
