One of the coolest things I ever saw in my career was a whole data processing pipeline built around jira. Incredibly interesting & surprisingly sensible way of running data processing pipelines. Very observable & clear to everyone what was happening.
Data would go stage by stage by stage. Cancel & retry options everywhere. Gates for human intervention/approval. Incredibly clear foundation for a data warehousing company. So glad I saw that. Typically data systems are there own thing, but using a more general tracking system like jira powerfully de-specialed what was happening & made great re-use of more human-first progress pipeline software.
I can definitely imagine HR software built from jira or something like.
