RiskSpectrum HRA help you standardize your HRA analysis process: - Performing and documenting the necessary HRA steps - Using the appropriate HRA method - Quantify the HFE´s human error probabilities (HEP) RiskSpectrum HRA includes a number of commonly-used HRA methods, such as THERP, ASEP, HCR/ORE, SPAR-H and HEART, etc. For each Human Failure Event (HFE) analysed, multiple methods can be used for quantifying the HFE probability and the different results can be compared. ![](https://www.riskspectrum.com/hubfs/image-png-Jul-27-2023-01-07-22-5193-PM.png)   ## Software In Action   - Pre-initiator Human Failure Events - Post-initiator Human Failure Events - Integration with RiskSpectrum PSA #### Pre-initiator Human Failure Events Pre-initiators consist of those actions associated with maintenance and testing (e.g., prior to the initiation of an accident) that degrade system availability. The pre-initiator HFE calculation methods available in RiskSpectrum HRA are: - THERP - ASEP - HEART - Screen Value ![](https://www.riskspectrum.com/hubfs/image-png-Jul-27-2023-01-12-43-5462-PM.png)       #### Post-initiator Human Failure Events Human failure events that represent the impact of human errors committed during actions performed in response to an accident The post-initiator HFE calculation methods available in RiskSpectrum HRA are: - THERP - HCR/ORE + THERP - ASEP - HEART - SPAR-H - Screen Value ![](https://www.riskspectrum.com/hubfs/image-png-Jul-27-2023-01-15-07-1653-PM.png) ![](https://www.riskspectrum.com/hubfs/image-png-Jul-27-2023-01-19-09-4506-PM.png)   #### Integration with RiskSpectrum PSA RiskSpectrum HRA version 1.2 was released in February 2025. It includes a number of great new features.  - Import from and synchronise with RiskSpectrum PSA – compare the records in the HRA database with the corresponding events in the PSA model - Extend the ID length to 50 characters in RiskSpectrum HRA to support long ID in RiskSpectrum PSA 1.5.1 and later versions. - The RiskSpectrum HRA interface support comparing the records in the RiskSpectrum HRA database with the corresponding events in the RiskSpectrum PSA model. ![HRA1.2 - synchronise data](https://www.riskspectrum.com/hs-fs/hubfs/HRA1.2%20-%20synchronise%20data.jpg?width=460&height=311&name=HRA1.2%20-%20synchronise%20data.jpg)   ![riskspectrum white logo](https://www.riskspectrum.com/hs-fs/hubfs/riskspectrum%20white%20logo.png?width=150&height=71&name=riskspectrum%20white%20logo.png)   ##### Software Software - [RiskSpectrum PSA](https://www.riskspectrum.com/riskspectrum-psa) - [RiskSpectrum PSA Macro](https://www.riskspectrum.com/riskspectrum-psa-macro) - [RiskSpectrum ModelBuilder](https://www.riskspectrum.com/riskspectrum-modelbuilder) - [RiskSpectrum HRA](https://www.riskspectrum.com/riskspectrum-hra) - [RiskSpectrum RiskWatcher](https://www.riskspectrum.com/riskspectrum-riskwatcher) - [RiskSpectrum SDP](https://www.riskspectrum.com/riskspectrum-sdp) - [RiskSpectrum I&AB](https://www.riskspectrum.com/riskspectrum-iab) - [R-DAT](https://www.riskspectrum.com/r-dat) ##### Solutions Solutions - [Probabilistic Safety Assessment (PSA)](https://www.riskspectrum.com/probabilistic-safety-assessment-psa) - [Reliability & Availability Assessment](https://www.riskspectrum.com/risk-reliability-and-availability-analysis) ##### Resources Resources - [Downloads & Resources](https://www.riskspectrum.com/downloads-resources) - [Training](https://www.riskspectrum.com/training) - [Contact Us](https://www.riskspectrum.com/contact) - [Privacy Policy](https://www.riskspectrum.com/privacy-policy) © 2026 RiskSpectrum Return to top
