# Core concepts

- [The FAIR model](https://docs.securemetrics.io/crq-pro/core-concepts/fair-model.md): How CRQ Pro structures risk with the Open FAIR taxonomy, and the distributions you can use at each leaf.
- [Scenarios](https://docs.securemetrics.io/crq-pro/core-concepts/scenarios.md): Scenarios are the unit of analysis in CRQ Pro. Create, organize, edit, and manage them.
- [Portfolios](https://docs.securemetrics.io/crq-pro/core-concepts/portfolios.md): Aggregate scenarios into portfolios to see combined exposure and top contributors.
- [Components](https://docs.securemetrics.io/crq-pro/core-concepts/components.md): Build reusable model pieces once and link them into many scenarios.
- [Workspaces](https://docs.securemetrics.io/crq-pro/core-concepts/workspaces.md): Workspaces are self-contained risk libraries. Use them to separate clients, business units, or experiments.
