**TLDR:** A sequenced, reproducible, and automation-friendly workflow of data transformation steps.

<p>A preprocessing pipeline ensures that data cleaning and transformation steps are defined in a consistent, reproducible sequence. Operations such as scaling, encoding, imputation, parsing, and feature creation are organized systematically within this flow. The pipeline approach guarantees that the same transformations are applied consistently during both training and inference. It is especially important in production environments for reducing data leakage risk and controlling model behavior. A good pipeline turns data science from an ad hoc analysis exercise into an engineering discipline.</p>
