URS-##### User Required Specifications
What’s the fastest way to generate a User Requirement? Perform a Failure Mode Effect Analysis that describes not servicing the customer.
Design the action plan to decrease risks of this failure ocurring.
Business Failure Mode Effect Analysis
BFMEA is a sublist of risks specifically affecting the business by means of customer quality impacting brand to supply chain and profitability. The BFMEA is the active list of known risks and the mitigation plan to address the risk within the User Requirements
Device Failure Mode Effect Analysis
DFMEA is a sublist of risks specifically focused on the individual devices and their failure risk identifications to personnel safety, Lead to impacts of Process Failure, Lead to a risk of Supply Chain Business Failure Modes leading to new

Process Failure Mode Effect Analysis
PFMEA is a Sub list of risks specifically focused on the Process failure modes and their identifications to personnel safety, risks to supply chain, business failure modes and even Causes to Device failure Modes.
User Failure Mode Effect Analysis
Informs the requirements for creating standard operating procedures
Training should not be the only tool to keep operators safe, a training requirement can only reduce severity, occurrence or detection by 1 degree, when additional risk reductions are needed it can be addressed by alternative solutions by adding an additional user requirement or with two person authentication
Risk Metrics
Severity
Severity: The severity of a problem is the degree of harm it can cause.

Occurrence
Occurrence: The occurrence of a problem is the frequency with which it occurs.

Detection Level
Detection: Detection is the process of identifying a problem. It can involve using various methods such as monitoring, testing, and analysis.

Risk Matrix
A risk product number is a numerical value that is used to measure the overall risk associated with a particular activity or situation. It is calculated by multiplying the severity of the risk, the occurrence of the risk, and the frequency of the risk. The higher the risk product number, the greater the risk associated with the activity or situation.
