Data Science Is Multidisciplinary

[Update :October 2016.  There appears to be some discussion about the Venn diagram I've proposed below. The central part of this diagram is not anything I can up with. It was a commonly used Venn diagram for Data Mining. Thanks to Polly Michell-Guthrie for providing the original reference for the Venn. I just added the outer ring of additional skills needed for the new area of Data Science. This was just my view of things back in 2012. Things have moved on a bit since then]

A few weeks ago I had a blog post called Domain Knowledge + Data Skills = Data Miner.
In that blog post I was saying that to be a Data Scientist all you needed was Domain Knowledge and some Data Skills, which included Data Mining.
The reality is that the skill set of a Data Scientist will be much larger. There is a saying ‘A jack of all trades and a master of none’. When it comes to being a data scientist you need to be a bit like this but perhaps a better saying would be ‘A jack of all trades and a master of some’.
I’ve put together the following diagram, which includes most of the skills with an out circle of more fundamental skills. It is this outer ring of skills that are fundamental in becoming a data scientist. The skills in the inner part of the diagram are skills that most people will have some experience in one or more of them. The other skills can be developed and learned over time, all depending on the type of person you are.
Can we train someone to become a data scientist or are they born to be a data scientist. It is a little bit of both really but you need to have some of the fundamental skills and the right type of personality. The learning of the other skills should be easy(ish)
What do you think?  Are their Skill that I’m missing?
