The "Not Invented Here Syndrome"

In programming, it is also common to refer to the “NIH syndrome” as the tendency towards reinventing the wheel (reimplementing something that is already available) based on the belief that in-house developments are inherently better suited, more secure, more controlled, quicker to develop, and incur lower overall cost (including maintenance cost) than using existing implementations. In-house developments are often collaborative with each other. When two in-house developments come together, it is informally known as “computer incest.”


Found when I was looking for a dependency-free XML-to-JSON parser wherein the author notes the “fine NIH tradition of JavaScript developers everywhere.” Reminded me of this
