Prerequisites
Before reading this report, ensure you have:
- At least one DFMEA document with scored failure modes (Severity, Occurrence, Detection)
- Access to the project wiki pages in Polarion (the report is a wiki dashboard page)
Open the DFMEA Summary Report
- Navigate to the project home page in Polarion.
- In the navigation panel, select System DFMEA Report under the wiki space pages.
- The report loads automatically — it queries all failure modes across every DFMEA document in the Risks space.
You can bookmark the report at: /polarion/#/project/{projectId}/wiki/System DFMEA Report
Understand the Executive Summary
The top section displays color-coded summary cards showing system-wide RPN distribution.
The report shows both pre-mitigation and post-mitigation counts in each card. Below the cards, a conditional alert box appears:
| Alert Type | Condition | Meaning |
|---|
| Danger | High RPN remains post-mitigation | Immediate action required — unacceptable risk |
| Warning | Medium RPN exists post-mitigation | Further evaluation recommended |
| Success | All failure modes are Low | All failure modes at acceptable levels |
Read the Module-Level Breakdown Table
The second section shows a per-document breakdown. Each row represents one DFMEA document:
| Column | Description |
|---|
| Module | DFMEA document name (clickable link opens document in risksheet) |
| Subsystem | Subsystem custom field from the document; defaults to “System” |
| Total FMs | Number of failure mode work items in this document |
| Pre-Mitigation | Low / Medium / High / N/A distribution of pre-mitigation RPN |
| Post-Mitigation | Low / Medium / High / N/A distribution of post-mitigation RPN |
The three-tier classification uses hardcoded thresholds:
- Low: RPN between 1 and 10
- Medium: RPN between 11 and 30
- High: RPN above 30
- N/A: RPN not yet scored (Severity, Occurrence, or Detection is missing)
DFMEA* or FMEA* with type riskSpecification.
Review High-Priority Action Items
If any modules contain failure modes with post-mitigation RPN above 30, a third section appears: Unacceptable Risk — High-Priority Action Items.
This table lists each module that still has unacceptable failure modes, with a recommended action column. Use this to prioritize:
- Open the linked module in risksheet by clicking the module name.
- Sort by the post-mitigation RPN column to find the highest-priority failure modes.
- Add or strengthen risk controls (mitigation tasks linked via the
mitigates role).
- Re-score Occurrence and Detection after mitigation.
- Verify the post-mitigation RPN drops below the threshold.
RPN Calculation Reference
The RPN displayed in this report is computed per failure mode as:
RPN = Severity (S) x Occurrence (O) x Detection (D)
- Severity (1-5): Set at the failure mode level; remains constant pre and post-mitigation
- Occurrence (0-5): How often the failure is expected to occur
- Detection (0-5): How likely the failure is to be detected before reaching the user
Each factor is scored in the DFMEA risksheet. Only Occurrence and Detection change after mitigation — Severity remains constant.
