What are the 10 steps of FMEA?

Here’s an overview of the 10 steps to a Process FMEA.

  • STEP 1: Review the process.
  • STEP 2: Brainstorm potential failure modes.
  • STEP 3: List potential effects of each failure.
  • STEP 4: Assign Severity rankings.
  • STEP 5: Assign Occurrence rankings.
  • STEP 6: Assign Detection rankings.
  • STEP 7: Calculate the RPN.

What type of FMEA does a Lean Six Sigma project use?

The two most popular types of FMEAs are Process (PFMEA) and Design (DFMEA). Each category has a scoring matrix with a 1-10 scale. Severity of 1 denotes low risk to the end customer, and a score of 10 denotes high risk to the customer.

What is the RPN in FMEA?

Formula: The Risk Priority Number, or RPN, is a numeric assessment of risk assigned to a process, or steps in a process, as part of Failure Modes and Effects Analysis (FMEA), in which a team assigns each failure mode numeric values that quantify likelihood of occurrence, likelihood of detection, and severity of impact.

How do you calculate an RPN?

The RPN is calculated by multiplying the three scoring columns: Severity, Occurrence and Detection. For example, if the severity score is 6, the occurrence score is 4, and detection is 4, then the RPN would be 96.

What is the difference between Six Sigma and FMEA?

Six Sigma eliminates product defects, errors and failures that detract from the customer’s experience. Failure Modes and Effects Analysis (FMEA) gives Six Sigma project teams a tool to help them predict the most likely process failures that will impact a customer.
