The article title would be much better as:
> "How a two-day cross-functional team moved an agency twenty years forward"
I'll go even further and say that Agile terminology should be avoided as much as possible, as we have already seen it corrupted into anti-Agile in the enterprise. Stick to the basics (short work cycles, cross-functional teams, clear explicit goals, quick constant feedback, etc) and a new organization will better maintain the true intent of Agile, rather than mindlessly cargo-culting the structures (sprint, iterations, agile team, scrum board, etc).
I've definitely experienced this. A large waterfall development group decides to call themselves Agile. They start proclaiming their mutant fast-waterfall as the One True Agile, adopting terms and structures to appear Agile.
Then you get invited to the hour-long "standups" attended by dozens of un-involved people, "stories" that amount to poorly worded system requirements, "grooming sessions" filled with chickens and "sprints" with development/release cycles that look oddly similar to what we had before they started calling themselves Agile.
It's just a rapid waterfall. Call it "rapid waterfall," or just keep calling it "waterfall" and increase your velocity. It confuses things when people that have worked in Agile shops come around and try to understand what you're doing.
Sidenote - I'd probably title the article "How a ten-person team moved a government agency forward twenty years in two days."
The permalink says "spring" so "sprint" is an improvement on the draft title anyhow. :)
Which are two of the main benefits of Agile (the third being efficiency due to process refinement).
So as far as enterprisey stuff goes, it's really not that (relatively) bad.
"Sprint" connotates a methodology. "Cross functional team" barely describes personnel vaguely.
"Period" doesn't connote activity, just time, so its not a great name for an activity.
"Effort" is a perfectly generic name for an activity, and carries no connotations related to what is special about this activity; even (perhaps especially to those unfamiliar with its use in software development jargon) "sprint" carries connotations of a fast, focused effort over a short time frame, which is quite appropriate here.
