“On one level, then, Cadbury can be seen as a classic example of Victorian industrial paternalism, albeit carried to greater lengths than in most other companies of the day. On another level, however, the Cadbury system resulted in a very strong, highly flexible organisation which, thanks to the strong levels of employee commitment and participation, could draw on a large bank of experience and intelligence to solve problems and undertake what amounted to continuous improvement. The employee participation system in particular meant that Cadbury was constantly upgrading its processes and products. Herbert Casson regarded Cadbury in the 1920s as one of the best-run companies in Britain, if not the world, and summed up the key to its success very succinctly: ‘At Cadbury, everybody thinks.”
