Financial analysis plays an important role in project management. It is used during project planning to create estimates and ensure projects are viable. During project execution, financial analysis allows managers to monitor budgets and address deviations. After project completion, financial analysis assesses how profitable the project was. Common financial metrics used in investment analysis include net present value (NPV), return on investment (ROI), internal rate of return (IRR), and payback period. These help evaluate investments and determine which projects to pursue.
