What to read to improve workflow?

Question

JIRA

Colleagues, tell me, what would you need to read in order to establish a workflow?
Our company "works agile", which seems not entirely correct.

So far, I am studying unstructured information, trying to figure out how to properly organize the work. I hope that the community will be able to suggest suitable literature and courses.
