Monte Carlo simulations in High Energy Physics play a crucial role in providing final physics results beyond the limitations of detector acceptance and resolution effects. These simulations serve as a bridge between theoretical models and experimental observations, enabling precise modeling of particle interactions, background estimation, and detector response. However, to ensure accurate and reliable outcomes, it is essential to tune the Monte Carlo generators using real data. Tuning aligns simulation parameters with experimental measurements, reducing systematic uncertainties and improving the fidelity of physics analyses. This presentation highlights the importance of Monte Carlo tuning in modern HEP experiments, discusses multi-parameter tuning methodologies, and illustrates its impact through concrete examples from electron-positron collider kinematics.
