FaultTree+ cloud — connected fault tree analysis
FAULTTREE+ CLOUD-based risk analysis software
See the causes.
Analyze the risk.
Act together.
Enterprise fault tree and reliability analysis in the cloud. Bring proven Isograph methodology, collaborative modelling and connected quality workflows into one cloud-based environment.
Made for engineering and quality teams working on safety-critical systems and regulated products.

A clearer path from failure to action.
Find critical causes sooner.
Break a complex failure scenario into logical relationships. Use automated modelling and analysis to investigate the combinations of events behind a system failure.
Keep teams aligned.
Work together in the cloud with consistent project data. Build analyses within teams or specialist areas, then bring them into a broader assessment.
Connect analysis to improvement.
Link the cause of a problem to the quality processes that address it. Give teams a clearer route from an event and its analysis to corrective action.
Start with an overview of your analysis work.

The dashboard gives you a practical starting point: reopen recent work, find failure models and understand activity before you return to the details.
- Open recently accessed analysis projects.
- Find recently used failure models from the same starting screen.
- Use charts and workspace information to orient your next review.
Build a model your whole team can follow.
Make the logic of a failure visible. The graphical editor brings the tree, navigation and editable properties together so you can move between the overall structure and the event you need to investigate.
- Represent dependencies and cause-and-effect relationships in a visual fault tree.
- Select gates and events to inspect and edit their parameters.
- Easily view calculations and version control.
- Create analyses in smaller teams or areas and combine them into a wider assessment.

Turn calculation results into an informed discussion.

Look beyond the diagram to understand what drives the assessment. The results workspace brings calculation outputs, methods and metadata into a structured view.
- Review availability, failure and reliability measures for the selected gate.
- Explore minimal cut sets and importance information.
- Inspect the calculation method and supporting metadata.
- Use the results to focus engineering review and improvement discussions.
Keep the model, its history and its context together.
A useful analysis needs more than a final number. Teams need to know which version was reviewed, what changed and how the model relates to the wider quality process.
Real-time collaboration
PeakAvenue FaultTree+ supports multi-user analysis directly in the cloud. Engineers and safety specialists can work in a shared environment rather than passing disconnected copies between teams.
Version history and traceability
Built-in version history, audit trails and reporting help retain the history of an analysis. Use that record to support reviews, inspections and documented engineering decisions.
Controlled working environment
Bring authorized users into centrally managed projects. Discuss access rights, model ownership and review practices as part of your configuration.
Proven methodology.
40+ Years of experience.
A modern cloud experience.
PeakAvenue FaultTree+ builds on Isograph analysis software developed since the 1980s. It brings established reliability methods into a SaaS environment for teams working in areas such as medical technology, aerospace, automotive, energy, transport and industrial manufacturing.
Support your standards-based work
FaultTree+ supports IEC 61025 and IEC 61508. Discuss with us how the modelling, documentation and reporting functions fit the evidence required for your specific assessment.
Reduce local deployment work
Cloud-based access and provider-managed updates reduce the desktop installation and patching work associated with individually deployed analysis software.
Choose a route that fits your organization.
Explore FaultTree+ cloud.
Choose cloud-based working, central project access and connected quality workflows. A personal demonstration lets you test the fit against your modelling, data and collaboration requirements.
Need a desktop deployment?
Reliability Workbench FaultTree+ remains available for local infrastructure and established desktop workflows. Compare deployment, connectivity, data control and maintenance before choosing.
Frequently asked questions.
What is PeakAvenue FaultTree+?
It is a cloud-based fault tree analysis solution within the PeakAvenue eQMS platform. It combines Isograph’s fault tree analysis methodology with cloud collaboration and links to quality and risk workflows.
Do engineers need to install the desktop application?
FaultTree+ is accessed through a supported browser with an internet connection. It does not require deployment of the desktop analysis application on each user’s computer.
Can several people work on an analysis?
Yes, real-time and multi-user collaboration is possible. Book a demo and see how access, versioning and review would work for your team.
How do we get pricing and evaluate the software?
Contact our team for a demonstration and a quotation based on your users, required modules and deployment needs. We will walk you through an example workflow so the demonstration can focus on your analysis priorities.
See your next fault tree analysis in a new light.
Bring your modelling challenges, review requirements and quality workflows. We will show you how FaultTree+ cloud could fit your team, and help you decide on the right next step.
