What are the weaknesses of the net present value?

Net Present Value (NPV) has several weaknesses, including its reliance on accurate cash flow projections, which can be difficult to estimate. It also assumes a constant discount rate, which may not reflect changing market conditions or project risk over time. Additionally, NPV doesn't account for the flexibility or potential future opportunities of a project, such as the ability to adapt or expand in response to market changes. Finally, it can be less intuitive for stakeholders who may prefer simpler metrics like payback period or return on investment.
