What is Workflow in AEM?
Workflows enable you to automate Experience Manager activities. Workflows consist of a series of steps that are executed in a specific order. Each step performs a distinct activity such as activating a page or sending an email message. Workflows can interact with assets in the repository, user accounts, and Experience Manager services. Therefore, workflows can coordinate complicated activities that involve any aspect of Experience Manager.
Business Use case
The core business use case is, as an author I should be able to add ‘n’ number of reviewers (AEM Users) to the workflow, and every user must approve or deny the request to complete the workflow.
