Stands for: Not Invented Here
The bias toward building something yourself rather than adopting a perfectly good external solution.
NIH shows up as distrust of outside libraries, standards, or vendors, sometimes justified by control and sometimes just ego or unfamiliarity. It is the counterweight to reuse: occasionally the right call for a core competency, but often expensive reinvention of a solved problem.
Also known as: NIH, NIH syndrome
