This scale is crucial because it helps firms identify the optimal size of their operations to maximize profitability while keeping costs in check.

In real-world terms, achieving the minimum efficient scale is often a game changer for businesses.

When they do, they can produce vehicles at a lower cost per unit, which helps them stay competitive in the market while potentially increasing their profit margins.
