Abstract
In an era increasingly dominated by digital transformation, data-driven decision making (DDDM) has become essential for businesses seeking to enhance strategic and operational effectiveness. This paper examines DDDM from a data science perspective, emphasizing the practical application of Python as a powerful tool for extracting business insights from complex datasets. The study outlines a structured approach to data analytics—encompassing data acquisition, preprocessing, exploratory data analysis, predictive modeling, and visualization—using key Python libraries such as pandas, NumPy, scikit-learn, seaborn, and matplotlib. Through illustrative case studies across sectors such as marketing analytics, financial forecasting, and supply chain optimization, the paper demonstrates how Python-enabled data science practices inform evidence-based business strategies. The findings underscore the critical role of data science in fostering analytical maturity within organizations, enabling them to respond dynamically to market shifts, customer behavior, and operational challenges. This research contributes to the growing body of literature on applied data science in business, offering both theoretical insights and practical guidelines for implementation.
