An organization must integrate an on-premises warehouse system with Salesforce. They require guaranteed delivery even if Salesforce is temporarily unavailable. Which integration pattern best addresses this requirement?

A program has several agile delivery teams building APIs. Leadership asks how to reduce rework and ensure APIs are discoverable and consistent across teams. What governance practice best addresses this?

A bank is mapping a new integration initiative to Catalyst. The team has identified multiple stakeholders and wants to uncover current pain points, constraints, and desired outcomes before proposing a solution. Which activity is most appropriate at this stage?

A product owner requests a single “mega API” that supports mobile, web, and partner needs to speed delivery. The integration team wants to follow API-led connectivity. What is the best recommendation?

A manufacturer is designing integrations across multiple systems. Several teams are independently creating APIs for similar concepts (e.g., Customer, Product) with different naming and inconsistent error responses. What is the best Catalyst-aligned governance action to prevent this going forward?

A financial services company needs to orchestrate a loan application process: verify identity, check credit, calculate risk, and then create records in multiple systems.

A healthcare company must comply with strict privacy requirements. A new partner portal needs limited patient data, but internal systems handle full records. The security team requires least privilege and consistent enforcement across all channels. Which design best meets these requirements?

An integration solution must handle spikes of 10x normal volume. During spikes, downstream systems can accept requests only at a steady rate. The business requires that no transactions are lost, and users should not experience system timeouts. Which pattern best addresses this requirement?

Billing requires guaranteed delivery, analytics can tolerate occasional duplicates, and shipping requires ordering. Which pattern BEST addresses these needs while minimizing coupling?

During testing, a client reports that the same payment request sometimes results in two charges. Logs show the client retried after a timeout, and the API processed both requests successfully. What is the BEST design improvement to prevent duplicate charges?

A program has multiple teams building APIs. Production incidents reveal inconsistent authentication policies and undocumented breaking changes. Which governance approach BEST improves consistency while enabling teams to deliver independently?
