A Cartridge is the core packaging and deployment unit in OSM that contains the fulfillment logic, data definitions, and automation rules for a specific product or service. It is the reusable template that allows different fulfillment patterns to be modeled and executed independently, making it the fundamental concept for multi-vendor, multi-product scenarios.

While concurrency (B) is a benefit, the most compelling architectural reason in OSM is the principle of modularity and separation of concerns. Decomposing by service into separate orchestration processes (often within different cartridges) allows teams to develop, update, test, and deploy the logic for one service (e.g., IPTV) without impacting the others. This is a key best practice for maintainability and agility.

For expected transient failures (like temporary network or system unavailability), the recommended pattern is to build resilience into the automation itself. An Automation Plugin, which contains the integration logic, should implement a retry mechanism (with delays and a maximum attempt limit). Only after these automated retries are exhausted should the process escalate, potentially to a manual task or an error state. This design minimizes unnecessary manual intervention.

In OSM, the central runtime entity is the Task. When an order is submitted, OSM creates a Task (or a hierarchy of tasks) as an instance of the defined orchestration process. This Task contains all the order data, tracks the current state, and progresses through the fulfillment flow by executing automation, creating subtasks, and updating statuses. The Sales Order and Order Line are typically source data *within* the task.

Dynamic Assignment is the OSM feature designed specifically for this purpose. By adding a filter to a Participant (like a group or role) on a manual task, you can define XQuery conditions that evaluate order data at runtime. In this case, the filter would check the order value and the agent’s group membership to determine if the task should be assigned and visible to them.

Outcome Mapping is the mechanism that controls the flow after a process element (like an automation or subprocess) finishes. The process element produces an outcome (e.g., ‘Success’, ‘Partial-Success’, ‘Specific-Error’). The Outcome Mapping defines which transition to follow based on that outcome value, enabling complex, conditional routing within the orchestration.

The OSM REST API is the modern, standards-based interface designed for stateless, resource-oriented integrations. It is ideal for external systems like dashboards to query order (task) data using HTTP GET requests with filter parameters (e.g., by customer ID). It is more lightweight and easier to consume than the SOAP web services for simple query operations.

The Data Dictionary is the metadata layer in an OSM cartridge. It defines the data model: the entities (like Customer, Service), their attributes (data types, constraints), and the relationships between them. It ensures data consistency, provides a common understanding for designers and developers, and is used by Design Studio for features like data mapping and XQuery validation.

The Rule Authoring feature (part of OSM’s Rules Framework) allows business logic and calculations to be defined as discrete rules outside the core orchestration. These rules can be authored, tested, and deployed independently from the cartridge. Changing a rule does not require redeploying the cartridge, enabling more agile updates to business policies and calculations.
