NHIS Syndrom, the "Not Invented Here Syndrome", as defined by Developer.Com, is a slightly tongue-in-cheek name for the tendency of both individual developers and entire organizations to reject suitable external solutions to software development problems in favor of internally-developed solutions. Closely related to the "let's re-invent the wheel" syndrome, NIHS can be seen in intensities ranging from a mild reluctance to accept new ideas all the way up to a raging software xenophobia. NIHS can be defined as a situation where an external solution is rejected only because it was not internally developed - in other words, there are no other factors that dictate an internally developed solution would be superior.

Be honest, never seen NHIS in your live ?
