- Build driving situations with the intuitive permutation matrix
- Identify malfunctions and hazardous events systematically
- Keep all analysis data in a central database
Risk Evaluation & ASIL Determination
Evaluate hazardous events and determine ASILs consistently.
- Classify severity, exposure and controllability with the evaluation matrix
- Calculate ASIL systematically with the risk graph
- Derive safety goals and safe states
- Transfer safety levels automatically to FMEDA and FTA
Catalogs, Documentation & Reuse
Standardize your analysis and keep results available for audits.
- Use customizable choice lists and predefined catalogs
- Reuse situation and hazard catalogs across projects
- Generate consistent documentation for assessments
- Track changes with versioning and change history
Integrated Engineering. Connected HARA.
EnCo ASE connects HARA with requirements, system structures and additional safety analyses so engineering information can be reused, traced and maintained across the development process.
Requirements
Connect requirements and relevant engineering information directly with the HARA.
System Design
Reuse system structures, interfaces and engineering relationships within the analysis.
HARA
Develop structured HARAs using connected engineering data instead of isolated information.
Safety Goals
Derive safety goals and manage them as requirements for downstream development.
FMEDA & FTA
Transfer ASILs automatically to quantitative and qualitative safety analyses.
Reporting
Use structured engineering data to create consistent reports and project documentation.
End to End Traceability
Maintain relationships between requirements, system elements, hazards, safety goals and downstream analyses.
Reuse Engineering Knowledge
Use existing information across analyses and projects instead of maintaining the same engineering knowledge multiple times.
Consistent Engineering Data
Work with connected data rather than isolated documents and reduce inconsistencies between engineering disciplines.
HARA becomes part of the engineering model. EnCo ASE allows teams to connect analysis data across requirements, system design and safety engineering instead of managing HARA as an isolated document.
Connect HARA with Your Engineering Toolchain
Import existing engineering information, exchange structured HARA data and export results for further use across your development environment. EnCo ASE helps integrate HARA into established engineering workflows instead of creating another isolated data source.
Import
Bring existing engineering and analysis information into EnCo ASE and use available project data as the foundation for further analysis.
Data Exchange
Exchange structured engineering information between EnCo ASE and other systems while preserving relevant relationships within your workflow.
Export
Export HARA information and analysis results for documentation, communication and further use in your engineering environment.
Toolchain Integration
Connect HARA activities with surrounding engineering processes and keep information available where your teams need it.
Use Existing Data
Build on engineering information that already exists instead of recreating it manually inside the HARA.
Reduce Duplicate Work
Exchange and reuse structured information across engineering activities and reduce unnecessary manual data transfer.
Keep Engineering Connected
Integrate HARA into the wider development process and maintain connections between relevant engineering information.
Your HARA does not have to live in isolation. EnCo ASE helps you move engineering information into, through and out of the HARA process while keeping it connected to your wider engineering environment.

Schedule Your Free ConsultationFrequently Asked Questions About HARA Software
Find answers to common questions about EnCo ASE HARA, the ISO 26262 methodology, collaborative hazard analysis and the integration of HARA into your engineering processes.
What is HARA software?
HARA software supports engineering teams in performing Hazard Analysis and Risk Assessment in a structured way. Instead of maintaining spreadsheets, a dedicated tool manages driving situations, hazards, hazardous events, ASIL determination and safety goals in one consistent data model.
What is EnCo ASE HARA?
EnCo ASE HARA is the hazard analysis and risk assessment module of the EnCo ASE engineering workbench. It combines a structured HARA methodology with multi user collaboration and direct integration into requirements, system design and further safety analyses.
Does EnCo ASE HARA support ISO 26262?
Yes. The HARA module follows the methodology of ISO 26262 for functional safety in road vehicles, including the classification of severity, exposure and controllability and the systematic determination of ASILs with the risk graph.
How does the permutation matrix support situation analysis?
The permutation matrix combines operational parameters such as road type, speed and environmental conditions into driving situations systematically. This reduces the risk of missing relevant situations and keeps the analysis reproducible.
Can multiple engineers work on a HARA at the same time?
Yes. HARA projects are stored in a central database and support multi user collaboration, change history and review workflows, so distributed teams can work on the same analysis without exchanging files.
How is HARA connected with FMEDA and FTA?
Safety levels determined in the HARA are automatically transferred to the quantitative and qualitative safety analyses in EnCo ASE, so FMEDA and FTA always work with consistent ASIL targets.
Can the evaluation be adapted to our internal process?
Yes. Customizable choice lists, predefined catalogs and configurable evaluation criteria allow the HARA to match your internal functional safety process while staying compliant with the standard.
Why use dedicated HARA software instead of Excel?
Spreadsheets become hard to maintain as situations, hazards and hazardous events grow and change. A database driven HARA tool keeps relationships consistent, supports collaboration and versioning, and reduces manual effort when the analysis needs to be updated.
