This report explores business decision-making through the lens of investment appraisal methods, focusing on the payback period and net present value (NPV) techniques. It assesses two projects, A and B, using these methods to determine the more favorable investment option. Project B is identified as superior due to its shorter payback period and higher NPV. The report also discusses the influence of financial factors such as investment value, project life, and liquidity, as well as non-financial factors like market competition, business environment (political, economic, social, technological, legal, and environmental), company culture, and management structure on investment decisions. The conclusion emphasizes the importance of both financial and non-financial considerations in effective investment decision-making.
