Microsoft Power Automate is all about process automation. Power Automate allows anyone with knowledge of the business process to create repeatable flows that when triggered leap into action and perform the process for them.
Power Automate is a low code way to do Workflow Automation and Robotic Process Automation (RPA). The same hundreds of data connectors, as well as UI automation that you had for Power Apps, applies to Power Automate as well.
No matter what you use today, what systems of record you have, what lines of business you have, you can go drive a ton of efficiency through automation.
