Thus the inquiery for this particular ENTP. I didnt understand what he was doing except that it is detrimental. .
It's withdrawal, it's called being stuborn. I would guess from what you've written, he is severerly pissed off at not being heard... too many pushy types (and yes you are SO part of the problem - you are struggling to hear some very clearly expressed views on this thread - by people who DON'T work with you).
So I wonder how you make an ENTP be heard... It's not about corroborating that his ideas are right, its about meeting him more than half way - why more than half way - because the whole bloody organisation is atempting to get him to behave as an ISxJ - which he is not, he is beginign to feel like a caged monkey and it's likely to be pissing him off.
I would think you have 14 layers of pissed off with minor shit to cut through before you get to his real issue. And there will be a real issue in there - almost certainly related to feeling very unapprecated by pushy types who aren't as creative/dynamic as he is.
Stop dictating and start finding out what he needs to be able to make the contribution required... this is likely to be not forcing him to kid on he can handle being stuck in a team who are so S type they need a prototype before they can even begin to think of what the hell he is talking about.
You are part of the problem, no amount of screaming
I love ENTP's or they
are all my best friends absolves you of soap boxing how pushy you are being to try and get someone to behave in an unnatural way for their type. Allowing people to work as much as possible within their own styles in order that they contribute to the highest possible level is simple good people management.
Heres an alternative perspectve for you... treat this guy like he is he victim of corporate bullying (irespective that you beleive he is the problem) and check out what that looks like from HIS perspective not yours.
Snuff from me,
I'm sure you will now come back with 100 word rant (yawn) on how fabulous you are and how much effort you are making to ram yourself down this guys throat etc etc.
None of us have to work for you, hence our perspective is merely holding a mirror up to what you are doing wrong with this guy... (FYI - quite trying to fix him, in all probablility its not him that needs fixing he is just behaving like an ENTP who is squashed).
