$(1)$ Assignment Instructions $$ Conduct a DFMEA for a concept of Gas Snow Blower

Select any existing concept of Gas Snow Blower to perform the DFMEA study and answer the following questions in a report format $($See assignment report instructions$-2)$: $$

$$

$1.$Develop a design tree diagram for the Overall, Systems and Components levels of the selected Gas Snow Blower $($You may need to identify the main systems and components, identify up to $15$ components$).$

$$

$2.$Identify the functions and functions tree for the overall, systems and components levels of the Gas Snow Blower $($identify up to $15$ functions and present them in a tree diagram$).$

$$

$3.$Identify $/$ list the design potential failures for the identified functions $($list up to $15$ failures$)$

$$

$4.$Select only $3$ potential failures from your list and identify the effects and causes for the related functions based on your experience$/$research of your concept. $($Document this in the attached DFMEA template$-$Excel file$)$

$$

$(1)$ Assignment Instructions $$ Conduct a DFMEA for a concept of Gas Snow Blower

$$

$5.$ For the selected $3$ potential failures, determine the Severity, Occurrence and Detection ratings based on your experience$/$research of the Gas Snow Blower and the ranking method$/$scale $($criteria$)$ that you determine $($Document this in the attached DFMEA template$-$Excel file$)$

$$

$6.$ For the selected $3$ potential failures, calculate the RPN accordingly, prioritize, record the recommended actions with the responsibility and target dates and re$-$calculate the RPN assuming that the recommended actions have been implemented $($Document this in the attached DFMEA template$-$Excel file$).$
