Which of these are used to measure return on investment (ROI)?

Contracting metrics relate to the terms and performance of contracts rather than the financial performance of investments. They assess factors such as compliance with contract terms or delivery timelines, which do not directly indicate the profitability or return yielded from investments.

Balance metrics typically focus on maintaining equilibrium in financial statements, such as ensuring that assets equal liabilities plus equity. While important for overall financial health, they do not specifically address the performance or returns generated from investments, thus making them unsuitable for ROI measurement.

Compliance metrics evaluate adherence to laws, regulations, and internal policies but do not provide insights into financial performance or investment returns. These metrics are crucial for risk management and operational integrity but do not reflect the financial success of investments.
