Scrum promotes cohesive, self-organizing teams. Scrum teams are tasked with finding the most optimal way to accomplish the work. To do this, they make decisions ranging from how best to meet goals to who should work on which tasks. Reaching group consensus can be difficult. Some opinions are more dominant than others; some voices more hesitant to speak out. Even in agreement, true consensus might not exist. One manifestation of this is the Abilene Paradox.
