The data scientist and the data engineer should work together

In 2012, Tom Davenport, a well-known management and technology thinker, and D.J. Patil, a computer scientist who later served as chief data scientist in the Obama Administration's Office of Science and Technology Policy, penned a provocative Harvard Business Review essay in which they argued that being a data scientist was the "sexiest job of the twenty-first century," as the title of the article stated.

However, Joe DosSantos, the company's chief data and analytics officer, disapproves of their judgement. "The essay established unrealistic expectations of what a data scientist can achieve," DosSantos argues, adding that these exaggerated expectations exacerbated the talent battle by encouraging employers to seek out "unicorn" applicants who possess all of the skills Davenport and Patel described.
