What is the advantage and disadvantage of PI Value Method?

The PI (Profitability Index) Value Method helps prioritize investment projects by comparing the value created per unit of investment, making it easier for decision-makers to allocate resources efficiently. An advantage of this method is that it provides a clear ratio that helps identify the most profitable projects relative to their costs. However, a disadvantage is that it may overlook the scale of investment, potentially favoring smaller projects that yield high returns but may not significantly impact overall profitability compared to larger projects.
