What is a Workflow Automation?

A workflow is any process with more than one step where the output of one step feeds the next: approve an expense, then notify finance, then update the ledger. Automating it means encoding that sequence, along with its branching conditions, into software so the process runs the same way every time regardless of who is available that day. Early workflow automation tools were rigid, if-this-then-that rule engines; modern platforms increasingly embed an AI step that can read unstructured input and make a judgment call, like classifying a support ticket's urgency, before handing off to the next deterministic step. Good workflow automation design separates the durable state of the process, such as which step it's on and what data it's carrying, from the logic that executes each step, so a workflow can survive a crash mid-execution and resume exactly where it left off. It also needs clear failure paths: what happens when a step errors, times out, or a human needs to intervene, rather than the whole process silently stalling forever.
