Innovation has become such an abused word everywhere, that nowadays, i dont even look at these articles and books.
Secondly, there are people who say," you should do innovation the way I am telling you". They will typically back it up with post facto stories of someone did that and did this.
Having met many such self-professed guru's, I am already tired of their lessons learned and abstracted to create their methods of innovation.
When you ask them to - lets do it, they say "yes yes, you do it, we are with you".
It is rare that these people will take the plunge into change!
To my mind, people who preach and preach - loose authenticity and credibility.
Are you a preacher or an innovator?
