Workflow Automation & Integration Flashcards

Which integration approach allows a document workflow to call an external business application's function in real time and wait for a result before continuing?

Answer: Synchronous web service call (request/reply)

A synchronous request/reply web service call blocks the workflow until the external system returns a response, making it suitable when the result is needed immediately to determine the next step.

In a document capture-to-ERP workflow, what does 'straight-through processing' (STP) mean?

Answer: Transactions complete end-to-end without any human intervention

Straight-through processing means a document moves from capture through validation, extraction, and posting to the ERP entirely automatically when no exceptions are detected.

A workflow architect needs to ensure that if one step in an automated process fails, partially completed actions are rolled back. Which concept addresses this?

Answer: Compensating transactions or saga pattern

Compensating transactions (or the saga pattern in distributed systems) undo the effects of completed steps when a downstream failure makes the overall transaction invalid.

What is the role of a 'transformation engine' in a document integration architecture?

Answer: Maps and converts data from one format or schema to another between systems

A transformation engine (often part of middleware or an ESB) translates data structures—such as converting an XML invoice from one schema to the format required by an ERP.

Which metric best measures the efficiency gain from workflow automation in an accounts payable process?

Answer: Cost per invoice processed and average cycle time

Cost per invoice and cycle time directly reflect the efficiency and speed improvements delivered by automation compared to manual processing benchmarks.

In a CDIA context, what does 'escalation' mean within a workflow?

Answer: Automatically rerouting a task to a supervisor when a deadline or SLA is missed

Escalation is a workflow mechanism that triggers when a task remains unactioned beyond a threshold time, typically routing it to a higher-authority user to prevent process stall.

When designing integration between a document imaging system and a line-of-business application, what is the advantage of using an Enterprise Service Bus (ESB) over point-to-point connections?

Answer: An ESB centralizes routing, transformation, and protocol mediation, reducing the number of direct integrations to maintain

An ESB reduces integration complexity from an O(n²) point-to-point mesh to a hub-and-spoke model, making it easier to add or change connected systems.
