In conclusion, the analysis of capital investment tools, namely NPV, IRR, MIRR, and Payback period, has illuminated the multifaceted nature of decision-making in financial strategy. Through the exploration of the local clinic scenario and the assignment of risk levels to various departments, we have witnessed the dynamic interplay of these tools in assessing diverse projects. Each tool brings its unique strengths and limitations to the table, addressing different dimensions of investment viability. While NPV provides a comprehensive view considering the time value of money, IRR and MIRR offer insights into the internal rate of return and potential reinvestment factors. Payback period, though simpler, underscores the importance of swift initial investment recovery. Ultimately, the choice of the preferred tool hinges on the specific needs and risk profiles of the clinic's departments. This essay underscores the significance of a nuanced approach to capital budgeting, where a thoughtful blend of these tools contributes to informed decision-making, aligning financial strategies with long-term organizational success
