My biggest issue with the teams of statisticians I've worked with before is that they lack a basic understanding of computer science. My biggest complaint dealing with the software developers on analytics projects is they don't understand statistics. I heard a great quote for which I don't remember the source (I paraphrase here): "A data scientist is someone who knows more computer science than a statistician, and more statistics than a computer scientist." The nature of the analytics world right now suggests that this type of specialty is sorely needed in many places.
