As templates for success case studies are failures.
It's possible some business types have not undergone a case study. But from the thousands that have it's time to ask, "What has been learned"? From failed businesses we learned what they did wrong; from those that succeeded what they did right. So it would seem that businesses would succeed if they avoided what the failures did and imitated what the successes did. But such is not the case. After thousands of case studies we find some companies succeed; most companies fail. Is failure caused by not reading the appropriate case study - possibly but not likely?
The cause lies in believing that case studies of successful businesses are templates for success. Case studies are not templates, they are summations of the output of talented people managed in an environment that attracts and holds talent.
A business manager with prolific case study knowledge should no more expect to duplicate a successful business than a sports team by like process should expect to duplicate a national champion. The talent and the environment in which it is managed are the nature and nurture of all organizations and these elements while identifiable are not inheritable.
In short, case studies have no genes.
Talent is the scarcest of all business resources and managing talent is the scarcest of all business skills. No case study to date has shown how the scarcity of these two elements can be made plentiful for distribution to all who desire them.
