Data scientists and machine-learning specialists are playing an increasingly integral role in many organizations' strategy and product development. Are most of these technologists involved in every part of their employers' data analysis and model training, or do they just specialize in specific areas? According to SlashData's Q3 2021 analysis, the answer is the latter: Most data scientists and machine-learning specialists focus on a few parts of the overall data science/machine learning (DS/ML) workflow. The highest percentage is involved in data exploration and analysis; far fewer participate in model deployment, project management, and model health and lifecycle management. The complexity of managing models may account for its relatively small percentage.
