We are working on designing a Workflow in our SaaS Application. Example usecase is (actual business usecase is different. I made up this usecase to explain my problem statement.) - consider Jira like application where we want to provide ability to user to perform action (send Slack Notification, Email, Create Sub Tasks from predefined template) when Task status becomes "Ready For Development". I wonder if anyone came across such problem or if there are open-source / paid solution you know we can leverage or take inspiration from.

I think it's worth taking a look at https://temporal.io/ and https://cadenceworkflow.io/docs/get-started/

Thanks for sharing! I will take a look
