After reading about this and the methodologies many years ago I implemented many of the precepts into my practice at the time (visual programming using a variety of workflow tools) and it really helped to prevent sprawl that is common with drag and drop workflow interfaces. It helps to enforce that discipline of not straying too far away from the desired path and handling exceptions. If it strays too far to the right then you know you need to look at things again and refactor. Worth reading.

How different is something like this to say, a Jira workflow?

I know there must be many like this but I think it might be particularly robust since it helped power the Buran launch and landing - which by all accounts was a bit of a miracle it all worked so well at first go.
