): The calculated risk priority value for the specific failure mode. Zone D: Mitigation & Tracking

: Early identification of weaknesses in the design phase leads to fewer redesigns and lower long-term costs.

What are you targeting? (e.g., automotive AIAG/VDA, aerospace MIL-STD, manufacturing) Do you need a design FMECA or a process/maintenance FMECA? Share public link

Elias felt the heat rising in his own collar. He had been the one to tell Sarah to "make it look nice." He had underestimated the complexity. He watched her click on a cell to adjust the RPN (Risk Priority Number) formula.

| Rating | Severity | Occurrence | Detection | |--------|----------|------------|-----------| | 1–2 | Very low | Remote | Almost certain | | 3–4 | Low | Low | High chance | | 5–6 | Moderate | Moderate | Moderate chance | | 7–8 | High | High | Low chance | | 9–10 | Very high | Very high | Very unlikely |

Existing design features or testing protocols meant to prevent or detect the failure. Detection (D): Numerical ranking of control effectiveness. Risk Priority Number (RPN): Calculated as (used alongside Cmcap C sub m for comprehensive risk profiling).

To eliminate guesswork, predefine your scoring systems here. Use Excel’s feature to link these tables directly to your main analysis sheet.

: Rank the ability of current controls to find the failure (1-10). RPN/Criticality Calculation : Use the formula to identify high-risk areas. Action Plan

For high-priority risks, define preventative or corrective actions (e.g., redesign, stricter maintenance).

Automatic "Red/Yellow/Green" highlights that draw your eye to the most urgent failures.

An FMECA should never be a static file filled out once to check a compliance box. Revisit the template whenever field data arrives, design changes occur, or corrective actions are finalized.

To ensure data consistency across multiple team members, restrict the scoring columns to numbers between 1 and 10. Highlight the Severity, Occurrence, and Detection columns. Go to the tab and select Data Validation . Under Allow, select Whole number . Set the minimum to 1 and the maximum to 10 . Best Practices for Running an FMECA in Excel
