The Cynefin model describes five different decision-making domains:
Disorder: “Clueless.” You don’t know which of the domains you are operating in. This is the murky area in the middle of the figure. Very dangerous, as any decision here is likely the wrong one.
Scrum and even waterfall can work well in the Obvious domain. More agile approaches are required for Complicated domains. A high level of skill and ability is needed for Complex domains. The GROWS Method™ will help you and your teams navigate the treacherous waters of Complex domains, and help you avoid slipping into Chaos. (Figure by Dave Snowden, CC BY-SA 3.0)
