What you will achieve

By the end of this tutorial, you will create your first FMEA (Failure Mode and Effects Analysis) document in TestAuto2, populate it with failure modes using Risksheet, assess risk ratings (Severity, Occurrence, Detection), calculate Action Priority, and link risk controls to demonstrate pre/post-mitigation risk reduction.

Prerequisites

  • TestAuto2 — Automotive Safety Solution installed and configured
  • User account with permissions to create documents in the Risks space
  • At least one System Element defined in your project (see Create System Hierarchy)
  • Basic understanding of FMEA methodology (optional: review AIAG-VDA FMEA Methodology)
  • System FMEA (SFMEA): Analyzes system/subsystem-level functional failures
  • Design FMEA (DFMEA): Analyzes component-level design characteristic failures
  • Process FMEA (PFMEA): Analyzes manufacturing process step failures
This tutorial demonstrates DFMEA creation—the most common starting point.

Step 1: Navigate to the Risks space

  1. From the Polarion navigation sidebar, click Risks under the Spaces section
  2. You will see the Risks space dashboard with statistics and document inventory
  3. Click the ➕ Create Document button in the toolbar
The Risks space dashboard displays live counts of failure modes, hazards, safety goals, and risk controls. The document inventory tree organizes existing FMEA documents by system element.

Step 2: Configure the new FMEA document

  1. In the Create Document dialog, set the following properties:
    • Space: Risks (pre-selected)
    • Document ID: DFMEA-ComponentName (replace ComponentName with your component, e.g., DFMEA-SensorHousing)
    • Document Type: Component DFMEA
    • Title: [Component Name] - Component DFMEA (e.g., Sensor Housing Assembly - Component DFMEA)
  2. Expand the Custom Fields section and select:
    • System Element: Choose the component you’re analyzing from the dropdown
  3. Click Create
Always prefix DFMEA documents with DFMEA-, SFMEA with SFMEA-, and PFMEA with PFMEA- to ensure proper categorization in reports and dashboards.

Step 3: Open the document in Risksheet

  1. After creation, Polarion opens the new document in LiveDoc view
  2. You will see an empty document with the Risksheet widget embedded
  3. Click the ** Open in Risksheet** button in the document toolbar
  4. The Risksheet interactive editor launches in a new browser tab
The Risksheet interface displays a multi-level table with column groups: Design Characteristics, Failure Mode Analysis, Risk Assessment, Risk Controls, and Post-Mitigation. The table is empty, ready for data entry.

Step 4: Add your first failure mode

  1. In the Risksheet table, click the ➕ Add Row button
  2. A new row appears with editable cells
  3. Fill in the failure mode details:
    • Characteristic: Enter the design characteristic (e.g., Housing Wall Thickness)
    • Failure Mode: Describe how the characteristic can fail (e.g., Insufficient wall thickness - structural failure)
    • Effect of Failure: What happens to the system (e.g., Camera module dislodges during crash, AEB system fails)
    • Cause of Failure: Why it might occur (e.g., Injection molding defect, material degradation)
  4. Press Enter or click outside the row to save

Step 5: Assess risk ratings

  1. Move to the Risk Assessment column group
  2. Click the Severity cell dropdown and select a rating from 1-10:
    • 9-10: Hazard without warning (safety-critical)
    • 7-8: Hazard with warning
    • 4-6: Major functional loss
    • 1-3: Minor inconvenience
  3. Select Occurrence (1-10): likelihood the failure will happen
  4. Select Detection (1-10): likelihood current controls will detect it before reaching customer (1 = almost certain detection, 10 = cannot detect)
  5. Watch the Action Priority (AP) column automatically calculate H (High), M (Medium), or L (Low)
TestAuto2 uses the AIAG-VDA 2019 Action Priority methodology, NOT traditional RPN (Risk Priority Number). AP is determined by a formula considering the interaction of S, O, and D values. See Action Priority Methodology for the full decision matrix.
  1. Scroll right to the Risk Controls column group
  2. In the Mitigation Action cell, click the **** link icon
  3. A picker dialog appears showing available Risk Control work items
  4. Click ➕ Create New Risk Control if none exist yet
  5. Fill in the risk control form:
    • Title: Design specification: minimum wall thickness 3.5mm
    • Description: Detailed mitigation approach
    • Control Type: Select Prevention (stops cause) or Detection (finds failure early)
  6. Click Create and Link
The Mitigation Action cell now displays the linked risk control ID and title. The Post-Mitigation column group becomes editable.

Step 7: Assess post-mitigation risk

  1. In the Post-Mitigation column group, enter revised risk ratings:
    • Post-Mitigation Severity: Usually stays the same (effect doesn’t change)
    • Post-Mitigation Occurrence: Reduced (mitigation prevents or reduces likelihood)
    • Post-Mitigation Detection: Improved (better controls increase detection)
  2. Watch the Post-Mitigation AP calculate automatically
  3. Verify the risk was reduced (e.g., from H to M or L)
StageRatingsAction Priority
Before MitigationS=9, O=6, D=7H (High)
After MitigationS=9, O=3, D=4L (Low)
Risk control effectiveness demonstrated: Severity unchanged, but Occurrence and Detection improved through mitigation controls.

Step 8: Use progressive workflow views

  1. At the top of the Risksheet interface, locate the View dropdown
  2. Select Initial Assessment view—hides post-mitigation columns for faster data entry
  3. Complete several failure modes in this view
  4. Switch to Mitigation Planning view—shows only risk controls and post-mitigation columns
  5. Return to Complete View to see all columns
Progressive views align with team workflows: safety engineers use Initial Assessment for risk identification, design engineers use Mitigation Planning for control definition, and managers use Complete View for oversight. See Use Progressive Workflow Views.

Step 9: Save and close Risksheet

  1. Click the 💾 Save button in the Risksheet toolbar
  2. Wait for the “Saved successfully” notification
  3. Close the Risksheet browser tab
  4. Return to the Polarion LiveDoc tab
  5. Click Refresh in the document toolbar to see your changes reflected
Risksheet auto-saves every 60 seconds, but explicitly saving ensures no data loss. Unsaved changes are highlighted with a yellow warning banner.

Step 10: Submit for review

  1. In the LiveDoc toolbar, locate the Workflow dropdown (currently shows Draft)
  2. Click Send for Review
  3. The document transitions to In Review status
  4. Project approvers are automatically notified and added as required signers
  5. Once approved, the document can be published for formal release

Verification

Your FMEA document is complete when:
  • At least 5 failure modes identified (industry best practice: 10-20 per component)
  • All failure modes have S, O, D ratings assigned (no blank cells)
  • All High and Medium AP failures have linked risk controls
  • Post-mitigation AP shows risk reduction for all mitigated failures
  • Document status is In Review or Approved
