What is a system?
• Network• Coherence• Agents
Making sense
Waterfall
Control
“Control is an illusion, you infantile maniac. Nobody knows what's gonna happen next: not on a freeway, not in an airplane, not inside our own bodies and certainly not on a racetrack with forty other infantile egomaniacs”

Gaming the system
Gaming the system II“One day in 2004 Jim exhorted the team to go faster. This team had an average velocity around 52 points per iteration. Their velocity would fluctuate by a few points, but generally remained steady. Yet just weeks after Jim asked the team to "sprint", the team's velocity jumped up into the high 80s!
I asked someone what happened.
She looked at me funny and said "These days around here if you sneeze, you get a story point." I shook my head, amazed at how a mature agile team, a team that had been assessed, trained and coached by two excellent Industrial Logic coaches, and myself could so suddenly inflate their story point estimates to appear like they were going faster.
My confidence in story points and velocity calculations began to erode after that experience.”
