# Choose by Business Scenario

> Enter resource access, semantic modeling, analysis, Assistant execution, and governance through real business goals.

Start with the business problem you need to solve. You do not need to read every concept first; after completing one real scenario, the [Product Concept](../overview/concept) is easier to understand.

| Your business goal | Suggested entry | Result |
| - | - | - |
| Answer “What are sales, orders, or procurement trends?” | [Multidimensional Model Introduction](../analytics/semantic-model/multidimensional-model-introduction), [Query Lab](../analytics/semantic-model/query-lab), [Semantic Analysis](../practices/semantic-analysis) | Metrics, dimensions, and query results have a clear definition |
| Connect SAP, a database, or a knowledge base | [Resource Access](../features/control-plane/resource-access), [Integration Model](../ontology/integrations/overview), [Ontology Workspace](../ontology/ontology-workspace) | External systems become searchable resources and entities |
| Unify customers, orders, equipment, or other business objects | [Ontology Studio](../ontology/ontology-studio), [Ontology Overview](../ontology/overview), [Snapshots and Projections](../ontology/snapshot-and-projection) | Reusable entities, relationships, and business actions are published |
| Let an Assistant query data, build a dashboard, or prepare a work order | [Action Discovery](../features/agent-execution/action-discovery), [Workbench and Resource Chat](../features/agent-execution/workbench-and-chatkit), [Apps](../apps/index) | The Assistant completes a governed task in business context |
| Control high-risk operations and trace decisions | [Policies](../features/governance/policies), [Approvals](../features/governance/approvals), [Execution Audit](../features/governance/audit) | Every execution has a permission decision, approval state, and evidence |

## Recommended first experience

If you only want to understand the system quickly, start with a read-only question:

> “Tell me the number of purchase orders, suppliers, and products this month, and show the data source and update time.”

The system locates business entities in authorized resources, discovers and simulates a query action, and returns the result with audit evidence. If your organization has a procurement resource, see [Procurement Quote Comparison](../apps/supply-chain/procurement-quote-comparison); otherwise use an existing semantic model and follow [Semantic Analysis](../practices/semantic-analysis).

## Continue by responsibility

After choosing a business scenario, follow the path for your responsibility:

* **Administrator:** start with [Secret Management](../features/control-plane/secret-management), [Resource Access](../features/control-plane/resource-access), and [Sync Jobs](../features/control-plane/sync-jobs).
* **Modeler:** define entities, relationships, and actions, then publish them in [Ontology Studio](../ontology/ontology-studio).
* **Analyst:** validate metric definitions in [Semantic Modeling Workspace](../analytics/semantic-model/semantic-modeling-workspace) and [Query Lab](../analytics/semantic-model/query-lab).
* **Assistant / Agent builder:** read [Agent Tools](../features/agent-execution/agent-tools) and [Action Discovery](../features/agent-execution/action-discovery).
* **Governance user:** use [Policies](../features/governance/policies), [Approvals](../features/governance/approvals), and [Execution Audit](../features/governance/audit).
* **Plugin developer:** start with [Adapter Extensibility](../ontology/integrations/extensibility) and [Ontology in Plugin Scenarios](../ontology/cases/plugin-scenarios).

When a step fails, use [First Failure Troubleshooting](./troubleshooting) and trace the first page state that is not ready.
