I like how Harold Jarche puts this:
All best practice case studies should have a warning label attached: Tacit Knowledge Not Included. Tacit knowledge is one of the few things that cannot be copied, and what makes creative non-standardized work so valuable. Tacit knowledge cannot be automated or outsourced. There are no best practices for tacit knowledge because it cannot be codified. Best practices can only help with lower value routine work. They can help refine your existing business processes, but they are not a source of innovation.
This is why I suspect the phrase “innovation process” is at best paradoxical, and the way it normally gets used, oxymoronic.
