A competing heuristic is a valid decision rule that directs action differently from another valid rule in the same situation. The conflict is not between right and wrong choices; it is between valuable outcomes, such as speed and completeness. section 3.2.2
Balancing speed and minority wisdom
During Big Picture EventStorming with more than ten people, splitting participants between pivotal events can improve progress and speed. Keeping everyone together can preserve complete and minority perspectives. A practical compromise is to work in subgroups, converge centrally about every 30 minutes, and ask who can relate to each part of the timeline. section 3.2.2
Use competing heuristics as a prompt to make trade-offs explicit:
- Name the valid heuristics and the different outcomes they favor. section 3.2.2
- Choose a workable combination when both outcomes matter, then refine it as recurring experience adds nuance. section 3.2.2
