A Workflow comprises of a set of actions executed at specific instances to automate routines in an application. When you trigger the workflow, it executes the set of associated actions. Workflows let you automate and map different activities, data, and people involved in the business process.
Assume an Order management application, in which a customer chooses a product and makes online payment. The order details are then sent to the warehouse for quality assurance check. Finally, the customer receives a notification when the shipment is out for delivery. All these actions can be automated using Workflows.
It can be used to calculate the total order value, send order details to the warehouse, notify the shipment and delivery status to the customer, and update the available stock. A payment workflow can also be initiated to make online payments easily. The process can be streamlined easily.
