Data Science

Data science is the practice of using data, statistics, programming, and domain knowledge to extract insights and support decisions. It ranges from exploratory analysis and reporting to experimentation, predictive modeling, and machine learning. What distinguishes data science from business analytics is the methodological depth: data scientists build models, run controlled experiments, and work with unstructured or large-scale data that standard reporting tools can't handle. The output is typically a model, a finding, or a measurement framework — not a dashboard.

Data science work that doesn't connect to a decision doesn't produce business value, regardless of technical quality. Teams can build statistically sound models around datasets that happen to be available, rather than around problems that matter — and those models tend to gather dust. The question to ask at the start of any data science project isn't "what can we learn from this data?" but "what decision would this improve, and who owns that decision?" Without a clear answer, the investment is speculative.
