Data-Driven Decision Making (DDDM) is the practice of making strategic choices based on the analysis and interpretation of empirical data, rather than relying solely on intuition or anecdotal evidence. This approach is a direct application of Data Science, which provides the methodologies for collecting, cleaning, analyzing, and visualizing data to extract actionable insights. Foundational concepts from Computer Science, such as algorithms, database management, and machine learning, provide the necessary tools and computational power to process and model large datasets, enabling organizations to identify trends, predict outcomes, and ultimately make more objective and effective decisions to optimize processes and achieve strategic goals.
