Dealing With Cowboys

"The coolest thing with Scrum," he said, "is that you can get rid of your long requirement phase and start deliver at once. You can also throw away your copy of MS Project. You don't have to create any big design documents or spend time in test phases any more. Release monthly and get paid earlier!"

Confused stares.

"Doesn't that sound great?" he continued excitedly.

More confused stares. Awkward moment.

"What's going on here?" he thought.

Muffled laughter.

"But we aren't doing any of that," the manager responded. "It sounds expensive and wasteful. Besides, we already release several times a week. This Scrum thing seems pretty pointless to me."

Long pause.

"I trust my tech lead and it looks like he was right again: We are already doing it the best way possible. We won't be needing your services. Thank you for your visit."

What's going on here? Is Scrum guy wrong? Who laughed? Why?
