The paper reviews the incidents of Lion Air Flight 610 and Ethiopian Airline Flight 302 to better understand the operational and management flaws of the Boeing 727 MAX. The investigation of the scenario was made by the respective authorities of each country, as well as FAA. The findings of the investigation revealed that initial causes of the crashes were serious issues in the system’s internal software. Now the paper aims to demonstrate the reason of failure in design with the assumptions that employees’ false assumptions and lack of communication lead to the failure in the system. Furthermore, key Strategic Operations Management Decisions were not properly addressed by the Boeing 737 MAX developmental and manufacturing stages. Thus, there is need to take strict measures to improve the management and avoid such incidents in future.
