Is perfectionism related to OCD? Is it right to say that a really strong attitude and stubbornness to do something is really similar to an obsession?

I'll try to explain better what I mean.

Let's take a really good developer or a really good scientist. Very often the reason which is leading him to be so good is the addiction to his work. 

For some guys, for example, the respect for the rule should be maniacal. 

So, is it possible to state that a strong perfectionism / addiction is often readable as a form of obsessive personality trait? (maybe ego-syntonic, and since not a disorder)
Perhaps check out the Obsessive Beliefs Questionnaire which is designed to measures dysfunctional beliefs related to OCD. There are several papers that examine the factor structure, and perfectionism is typically seen as one of the major aspects of obsessive beliefs.

However, it seems to be a particular form of maladaptive perfectionism. See these perfectionism items from the OBQ:


  
  In order to be a worthwhile person, I must be perfect at everything I do
  If I can’t do something perfectly, I shouldn’t do it at all
  Even minor mistakes mean a job is not complete
  For me, things are not right if they are not perfect
  For me, making a mistake is as bad as failing completely.
  I must keep working until it’s done exactly right.
  


Thus, this is more than just doing your best to achieve good outcomes.
