Why Most Data Science Projects Fail (And How to Fix the Structure)

The video highlights that most data‑science initiatives crumble because they start as ad‑hoc notebooks on a single laptop, lacking any disciplined project structure. It argues that a reproducible, collaborative, and scalable workflow is not optional but essential for delivering business value. It walks through popular methodological frameworks—CRISP‑DM, OSEMN, KDD, and SEMMA—showing how each maps a project from business understanding through data preparation, modeling, evaluation, and deployment. These frameworks provide a repeatable roadmap that keeps teams aligned and allows iterative refinement. Common pitfalls are illustrated: hard‑coded file paths, monolithic Jupyter notebooks, committing raw datasets to Git, and missing README documentation. The speaker recommends practical fixes such as using relative paths, breaking code into modular scripts, employing data‑versioning tools like DVC, and maintaining clear project documentation. By institutionalizing these practices, organizations can move beyond one‑off experiments to production‑ready models, improve team efficiency, and protect investments in data science talent. The shift enables faster scaling, easier onboarding, and more reliable insights for decision‑makers.
