Leveraging empirical process control theory
Scrum's foundations lie on empiricism, as opposed to following a pre-planned process. Empiricism in the philosophy of science, which emphasizes on knowledge acquisition through hypothesis, theories, experimentation, and the validation of results. For example, the scientific method is based on empiricism.
