Presented at WebVisions May 2013 in Portland, OR. What happens when you take teams that have traditionally not worked together closely? Teams that are used to the "delivery mindset" and instead try to bring great experiences to life in a collaborative manner? All hell breaks loose! We are all creatures of habit and we all bring baggage to the table. And events conspire to tear our teams apart. This talk takes the flip side of how teams work together well and instead looks at behaviors and events that can stifle team collaboration for Lean UX teams. 18 anti-patterns are used to sensitize you for what to watch out for as well as strategies to overcome each.
