What you will achieve

By the end of this tutorial, you will have accessed the Nextedy demo server, explored pre-configured FMEA and HARA risk analysis projects, understood the core capabilities of Risksheet (including RPN calculation, conditional formatting, downstream task management, and review workflows), and determined whether Risksheet meets your risk management requirements before deploying it on your own Polarion server.

​
Prerequisites

Contact Nextedy to receive demo server credentials. The demo includes pre-configured FMEA and HARA example projects with sample risk data already populated. Demo projects are available for both FMEA (automotive/industrial) and HARA (ISO 26262 automotive safety) configurations.

​
Step 1: Access the Nextedy Demo Server

Open your browser and navigate to the Nextedy demo Polarion instance. Log in with the demo credentials provided by Nextedy. You should see the Polarion home page with a list of available projects. The FMEA and HARA demo projects appear in the project list alongside any other demo projects.

​
Step 2: Open the FMEA Demo Project

Navigate to the FMEA demo project from the project list. In the left sidebar, look for the Risksheet topic entry (the tool name may be customized — it appears as “Risksheet” or “Risk Analyses” by default). You should see the document selection interface — this is the Risksheet home view that lists available risk analysis documents. It allows you to browse folders, select existing documents, or create new ones from templates.

​
Step 3: Explore the FMEA Risksheet

Open the FMEA risk analysis document. The Risksheet grid loads, displaying an interactive spreadsheet-like view with:
  • Risk items as rows, each representing a failure mode with its causes and effects
  • Column groups organizing related columns (e.g., severity, occurrence, detection under “Initial Assessment”)
  • Color-coded RPN cells showing risk levels through conditional formatting using cell decorators
  • Row headers with visual color indicators based on the revised RPN value
  • Hierarchical levels with cell merging for failure mode/cause/effect structures
You should see risk items with populated severity, occurrence, and detection ratings, and automatically calculated RPN values in the formula columns.
Row HeaderFailure ModeUpstream Req.SevOccDetRPNNew SevNew OccNew DetNew RPN

:green_circle:Data corruptionREQ-231027140101550
:yellow_circle:Calibration lossREQ-31758280746168

​
Step 4: Examine the RPN Calculation

Click on an RPN cell to observe the formula. The initial RPN is calculated using the commonRpn formula, which multiplies severity, occurrence, and detection ratings: 
RPN = Severity x Occurrence x Detection
The revised RPN (after mitigations) uses the commonRpnNew formula with the post-mitigation ratings. The conditional formatting (cell decorators) applies color coding based on RPN thresholds:
RPN RangeBackground ColorText ColorRisk Level
1 — 150Green (#eaf5e9)Dark green (#1d5f20)Low risk
151 — 350Yellow (#fff3d2)Dark yellow (#735602)Medium risk
> 350Red (#f8eae7)Dark red (#ab1c00)High risk
The row header also reflects the revised RPN color, giving you at-a-glance risk assessment for each row.

​
Step 5: Explore Downstream Tasks

Look for mitigation task columns in the grid. Each risk item can have one or more downstream tasks (mitigation actions) linked to it. To explore:
  1. Right-click a row that has tasks populated
  2. Select the option to open the linked task item
  3. The task work item opens in the Polarion item editor
You should see the task work item with a link back to the parent risk item. Tasks are standard Polarion work items connected through configurable link roles, which means they participate in Polarion’s full traceability model.
Downstream tasks are configured via dataTypes.task in risksheet.json. The demo project may use work item types like “Mitigation” or “Corrective Action” depending on the FMEA template.

​
Step 6: Explore Upstream Traceability

Look for upstream columns in the grid that display linked requirements or design elements. These columns show data from work items linked above the risk item in the traceability hierarchy. Upstream traceability connects risk analysis to the requirements and design elements being assessed.

​
Step 7: Open the HARA Demo Project

Return to the project list and open the HARA demo project. Navigate to the Risksheet topic and open the HARA risk analysis document. You should see a similar grid layout but with HARA-specific columns for:
  • Hazard severity — severity of the hazardous event
  • Exposure — probability of exposure to the operating situation
  • Controllability — ability of the driver/user to avoid the harm
These parameters map to the ISO 26262 ASIL (Automotive Safety Integrity Level) determination process. The formula columns compute the ASIL rating from severity, exposure, and controllability inputs.

​
Step 8: Try Editing a Risk Item

Click on a cell in the grid to enter edit mode. Change a severity or occurrence value and observe how the RPN recalculates automatically. The row header color updates to reflect the new risk level.
  1. Click on a severity rating cell
  2. Select a new value from the dropdown (severity ratings are configured as Risksheet ratings)
  3. Observe the RPN column updating immediately
  4. Click Save in the toolbar to persist your changes
The data is saved as standard Polarion work items, meaning all changes are versioned and auditable through Polarion’s built-in revision history.
The demo server may have restricted permissions. If you cannot edit cells, verify that your demo account has write access to the project. Cells that appear with a read-only indicator cannot be modified due to column configuration or permission settings.

​
Step 9: Examine the Review Workflow

If the demo project has review workflows configured (visible through a review column or review panel), explore how reviews are created and managed:
  • Comment-based reviews store reviews as Polarion work item comments (configured via reviews.reviewManager: "CommentBased")
  • Each review displays the author name, timestamp, and comment content
Risksheet is purpose-built for risk analysis workflows (FMEA, HARA, TARA, STRIDE, CVSS). POWERSHEET is a separate Nextedy product for general-purpose spreadsheet views of any Polarion work items. Both products share the same interactive grid technology but serve different use cases. Risksheet can unlock additional features when a valid POWERSHEET production license is present, but each product is licensed independently. Evaluation/trial POWERSHEET licenses do not enable these enhancements.
