Simple workflow engine

I would love to see some sort of built in workflow engine to flag/tag/mark todo on assets meeting a certain criteria.
For example, different departments work on different things here - but everyone updates the asset with the latest information and adds things such as "third party ID", "in xyz system".
I would love to have a workflow of "send webhook"/"tag with x"/"send email" etc, if an asset has a checkbox ticket/unticket, if field is empty etc.
