Part $1$: FEMA

Obviously, door locks can be of different types each with different kinds of parts. In this technical assignment choose

only one lock type and attempt to answer the following questions:

How can each part conceivably fail?

What mechanisms might produce these modes of failure?

What could the effects be if the failures did occur?

Is the failure in the safe or unsafe direction?

How is the failure detected?

What inherent provisions are provided in the design to compensate for the failure?

Steps and Requirements:

$1-$ identify at least $5$ failure modes that are inherent in the product.

$2-$ develop a complete FMEA using the template that is available in the course page at Blackboard.

$3-$ provide accurate estimates for the severity for each function that you identified and provide a

proper justification for the level you decided for it$.$

$4-$provide accurate estimates for the occurrence rate for each function that you identified and

provide a proper justification for the level you decided for it$.$

$5-$ provide accurate estimates for the detection likelihood for each function that you identified and

provide a proper justification for the level you decided for it$.$

$6-$ compute the risk$-$priority$-$number for each function and discuss the recommended actions to

each.

Part $2$: Cause and Effect Diagram

Develop an Ishikawa diagram for ONLY one of the failures identified in Part $1.$ Provide detailed

description of causes that can lead to that failure.
