Sensitivity of Life Cycle of Household Waste to the Environmental Risk

This case illustrates the use of the Failure mode and effects analysis for a development effort of about one year. Prior to implementing the Failure mode and effects analysis, the risk management process was based on using a brainstormed list of risks within each cycle phase. Each risk was assessed for its impact and a response plan was generated to avoid the risk or take advantage of an identified opportunity. The process was not effective for risk response planning as there was no scoring method for risk prioritization. The Failure mode and effects analysis technique was introduced as a way to systematically capture risk events, score them, and then respond to those that posed the most threat to the cycle. The Failure mode and effects analysis for cycle included a total of ۱۰ identified major risks and ۲۱ threats by interview with contractors and filling checklist of EMS and the risk form. Checklist prepared based on existing guidelines of consumers recycling household waste. Once the risks were identified, the ۷ region of Tehran-Iran added known symptoms for the risk and assigned the consequence, exposure, and probability values. Charts of the risk score and the RPN values were generated by risk ID.
