Not Invented Here Syndrome is a typical
scourge of poor managers. Everyone who has worked long enough has run into someone suffering from NIH Syndrome; no idea is any good unless the
manager can take credit for it, i.e., invents it.
A typical case runs like this: John Doe makes a suggestion to improve widget. Doe's manager shoots idea down out of hand. Six months later, Doe's manager implements suggestion as his own idea - figuring no one will remember that he shot down Doe's very same suggestion.
Managers who suffer from Not Invented Here Syndrome are a detriment to any organization. Obviously their focus is only on making themselves look good - even at the expense of others and the good of their organization.
Not Invented Here Syndrome is the antithesis of employee empowerment.
