Do I need a workflow engine or is Zapier enough?

Depends on complexity. Zapier handles simple integrations well. For complex processes with conditions, approvals, exceptions, and audit requirements, you need a proper workflow engine.

What's the difference between workflow and orchestration?

Workflow typically refers to business process coordination (often with human tasks). Orchestration often means technical coordination of services/systems. The terms overlap significantly.

Should workflow engine be custom-built?

Almost never. Mature platforms exist (Camunda, Temporal, Power Automate). Custom builds are expensive, hard to maintain, and lack features. Use platforms; customise through configuration.

How do workflow engines handle errors?

Good engines include: retry logic, error escalation, compensation transactions, dead letter queues, and alerting. Error handling should be designed into workflows, not afterthoughts.

Workflow Engine

Software that executes and manages business workflows, routing tasks, handling approvals, and tracking progress through multi-step processes.

In-Depth Explanation

A workflow engine is the core software component that executes business workflows. It manages task routing, enforces business rules, handles approvals, and tracks status through complex processes.

Workflow engine capabilities:

Process execution: Run defined workflows
Task routing: Assign work to the right people/systems
State management: Track where each item is
Business rules: Apply conditions and logic
Integrations: Connect to external systems
Monitoring: Track SLAs and bottlenecks

Types of workflow engines:

BPM engines: Full business process management (Camunda, Activiti)
Lightweight: Simpler workflow tools (Temporal, Conductor)
Low-code: Visual workflow builders (Power Automate, Zapier)
Document-centric: Focus on document routing

Key workflow patterns:

Sequential flow
Parallel execution
Conditional branching
Loops and iterations
Human tasks and approvals
System integrations

Business Context

Workflow engines are the backbone of process automation. They ensure consistency, visibility, and control for mission-critical business processes.
