Maestro user guide
This section outlines practical implementation scenarios that help you apply Maestro effectively to real-world business needs. These patterns are informed by common BPMN practices.
Each pattern reflects a repeatable modeling approach that can be reused across departments, domains, and process types.
Use case: A request (e.g., invoice, access, quote) needs to be reviewed and approved by a person.
Pattern: Start event → Service Task (data prep) → User Task → Gateway (approved?) → End.
Highlights:
- User Task can be assigned dynamically.
- Optional use of Action Apps for task forms.
- Escalation paths supported via boundary events.
Use case: Your process needs to call an API or receive data from an external system.
Pattern:
- Service Task → Send Task (outbound).
- Or: Receive Task (event-driven trigger).
Highlights:
- Connectors (via Integration Service) handle REST, SOAP, etc.
- Use data mapping and variables to configure payloads.
- Works well with queues or transactional data pipelines.
Use case: You want to separate decision logic from flow logic (e.g., risk evaluation, eligibility).
Pattern: Task → Business Rule Task → Gateway based on result.
Highlights:
- Use Rule projects in the same solution.
- Input/output mapped via properties panel.
- Supports DMN 1.3 and UiPath Decision support.
Use case: You need to process a list of items in parallel (e.g., validate multiple invoices, review multiple contracts).
Pattern: Task with Parallel Multi-instance Marker.
(loop over list variable)
Highlights:
- One task instance per item.
- Use Parallel or Sequential markers.
- Outputs can be aggregated or joined later.
Use case: The next step in the process depends on input data or rule output.
Pattern: Gateway with conditional sequence flows.
Highlights:
- Define condition expressions using the Expression Editor.
- Always define a default path to avoid runtime faults.
- Conditions can reference variables or business rule results.
Use case: You need to reuse a segment of logic across multiple processes.
Pattern: Call Activity → Reuse process defined in another Maestro project.
Highlights:
- Sub-processes share variables and context
- Call Activities trigger new process instances
Use case: Delegate a complex or intelligent task to an AI agent or planning system (e.g., summarization, classification).
Pattern: Service Task → Start and wait for agent.
Highlights:
- Supports external agents like CrewAI, LangChain, or custom APIs.
- Runtime status monitored in Maestro.
- Works in conjunction with parallel flows or escalation paths.
