The document discusses why companies do not need perfectionist data scientists and should instead focus on small groups working on problems step-by-step. It notes that very few people are true perfectionists, and seeking them out would be too expensive. Instead, having multiple small groups of data analysts working on targeted problems can help companies make incremental improvements while spending less money. The conclusion is that companies do not need single highly-skilled data scientists but can achieve results through collaborative work by groups of analysts.
