You are an engineer reviewing the production line for a smoke alarm. The following is an extract of the FMEA that has been conducted on the product and you have been tasked with reviewing production costs and the safety of the product.

You believe this will reduce the "Detection value in the FMEA analysis for the Sensor A to a value of 1 Option B:
Option B: You can change the manufacturer of the alarm housing to one with better quality casting. This will reduce the "Occurrence of the problem of the alarm housing breaking at first removal to a a value of 3 but will cost an additional $0.50 per unit. Answer the following questions: 1. For Option A, how long will it take to break even? (Answer in years to 2 decimal places) 2. For Option A, what is the new RPN for the Sensor A failure listed? ge 3. For Option B. how long will it take to break even? Answer in years to 2 decimal places) 4. For Option B. what is the new RPN for the Alarm housing failure listed? 5. Which option will you suggest to your manager? (A or B) Justify your answer (You can consider the costs, revenue breakeven, the FMEA, improved safety etc. for your answer but you must to select one of the options and give a justification for this based on the factor you think is most significant as an engineer giving a recommendation)
