The study evaluates three options for Space Sky Flight Ltd to launch their product, analyzing their profitability and suitability. Option C, selling the patent rights, is recommended due to its highest NPV and faster cash inflows. Other factors and external environment should also be considered before making a final decision. The cash outflow, cash inflow, and net working capital for each option are presented. Machinery, working capital, and total capital outflow are outlined. The total cash inflow is calculated based on projected sales volume and price per unit for each year (Morden, 2016; Hopkinson, 2017).
