Box 1: Business process flow
A business process flow is a visual guide meant to help users complete a business process by using a set of predefined stages. Users are not limited on how long they run a business process or how long they have a stage open.
Box 2: Business rule
Box 3: Power Automate
A Power Automate flow does not have any visual components like a business process flow. Power Automate flows can be configured to work with many different data sources, and a flow can connect to many different data sources within the same flow. A flow can be configured to time out if it is not completed in a certain time and can be triggered to move between steps based on data or user interaction.
