Invented here and not invented here are equal signatures of crappy developers, in my opinion. I'll admit there's some skill involved, sometimes, in the engineering efforts of the NIH minded developer. But I've also seen NIH developers insist on building things like CI servers, company wikis, and message queues. And none of them have even been tangentially better than the alternatives. They're both mindsets that speak to immaturity and lack of judgement, but man, I've seen way more of NIH than IH, and in a lot more business-destructive senses
