I don't like the idea of gamification. At least the "do stuff -> get points" kind of gamification.

I find that it makes people do the right thing for the wrong reasons. I should work hard because it's what I'm supposed to do. It is the right thing to do! Not to say that these systems can be "gamed" (pun intended). It gets incredibly demoralising for a hard worker, doing stuff by the book, to see a colleague exploiting and cheating the system.

Imagine it with software development. You get points each bug solved. The hard worker will carefully correct it, the right way, with proper testing, acessing impacts, all that stuff. The "exploiter" will just thow around a quick hack so that it works correctly, in about 1/5 of the time. And he can use the remaining 4/5 of the time to solve more bugs, and earning more points!

TL;DR: It encourages people to do stuff for the wrong reasons and, in my opinion, that is bad and wrong.

I also dislike gamification, because it usually puts emphasis on arbitrary metrics that are not necessarily related to success.

Having said that, I want to note that the exploiter you're talking about exists in every organization, whether they use a scoring/ranking system or not. Gamification systems are abusable, but hardly any more abusable than any other human management system.
