I'm not sure why nobody provides a task tracking tool that has tasks organized hierarchically (with chord/circular dependency. This is the real world, regardless of the argument about subjective processes. If you can't see where in your workflow, that 1 task (even from another team's workflow) is impacting multiple other workflows at-a-glance, the tool is too primitive. Subtasks don't cut it.

JIRA is the most popular of all tools on the market, which are glorified gantt points across disparate fragmented views. This is an element of modern tech that makes large organizations hilariously inefficient.
