In Salesforce Communications Cloud Order Management, orchestration steps execute through Apex-based orchestration jobs. When order volume rises sharply---as happens when additional sellers or regional teams begin submitting orders---the system may hit Salesforce's platform limit for queued Apex jobs (50 number of licensed Salesforce users). Once this limit is reached, orchestration fails.

Salesforce's official scalability recommendation is to enable Platform Events for Orchestration. This switches Order Management from synchronous Apex-queue processing to asynchronous, event-driven orchestration, which drastically reduces reliance on Apex jobs. Platform Events allow OM to process far more concurrent orchestration steps without hitting queue limits and provide better throughput and resilience for enterprise-scale flows.

Options A and B are incorrect because Salesforce does not increase Apex job limits, and splitting orders is not a best-practice. Option D reduces automation and violates OM design principles.
