An expert's competence in a particular subject may derive from long observation and real-world experience, and is not dependent on formal training or having an academic degree in the subject. Where the expert's factual conclusions partially contradict a plaintiff's deposition testimony, the expert opinion is still sufficient to defeat summary judgment where the opinion is based on other record evidence and is neither speculative nor conclusory.
