A model-based RAMS framework.

A practical framework for moving from federated compliance tools and fragmented spreadsheets to connected engineering evidence, continuous analysis and earlier risk-informed decisions.

More than a software upgrade

Move RAMS from fragmented compliance to connected capability.

Transitioning to model-based RAMS changes how engineering teams understand reliability, safety, maintenance and risk. The objective is not simply to digitise existing documents—it is to connect the decisions and evidence that shape system performance.

A universal model-based framework replaces disconnected analyses and late-stage risk discovery with a deliberate system-level approach that designs resilience in from the start.

The breakthrough is organisational: RAMS knowledge becomes structured, traceable and reusable across engineering disciplines and lifecycle phases.

A connected foundation

The model-based RAMS framework.

Model-based RAMS framework connecting engineering disciplines and lifecycle decisions — The framework aligns system knowledge, model views, analyses and decision evidence rather than treating each RAMS deliverable as a separate activity.

Shared system model

Common architecture, functions, dependencies and failure knowledge provide the source for analysis.

Connected analyses

FMEA, FTA, reliability, maintainability, RCM and PHM reuse governed system information.

Continuous evidence

Analyses evolve with the system instead of becoming static snapshots.

Decision support

RAMS outputs inform trade-offs, mitigation, certification and lifecycle value.

How the capability works

A disciplined model-centric way of working.

Define system and mission contextEstablish the architecture, functions, environments and operating profiles that frame risk.
Capture governed engineering knowledgeStructure failure, reliability, safety and maintenance data around the system model.
Run connected RAMS analysesUse the shared model to produce complementary analysis views and engineering evidence.
Compare mitigations and trade-offsEvaluate design, cost, availability, safety and sustainment impacts together.
Maintain the digital threadKeep assumptions, decisions and outputs traceable as the product and evidence evolve.
Feed operational learning backUse in-service data and lessons to improve future configurations and programs.

The impact of model-based RAMS

What changes for the organisation.

Earlier influence

RAMS evidence reaches design decisions while alternatives remain open.

Higher integrity

Shared source data reduces contradiction between documents and disciplines.

Faster change response

Connected analyses can be updated when system configuration changes.

Knowledge retention

Engineering logic remains available beyond individual people and projects.

Lifecycle optimisation

Reliability, cost, maintenance and mission outcomes can be evaluated together.

Strategic capability

RAMS moves from a compliance activity to continuous engineering decision support.

Industry perspective

RAMS is moving onto the critical engineering path.

“RAMS is moving onto the critical engineering path. It is being held back by federated tools not designed to effect greater change in the industry.”
RAMS Industry Study participant

“Current RAMS tools are keeping RAMS analysis out of key decisions—and that will not change without organisational transformation.”
