There are two modes for using the complete map. The first is structured analysis — working through F1 to F9 in order, producing written outputs, taking the time each framework deserves. This is appropriate for architecture reviews, quarterly roadmap assessments, post-mortems where learning is the goal. The AT6 (Flexibility vs Simplicity) tradeoff applies here: structured analysis is thorough but slow.
The second mode is rapid triage — moving through the map in minutes rather than hours, using each framework to bound the problem space rather than fully characterise it. F1 identifies category, F2 names the hard constraints, F3 flags the most exposed failure modes, F6 confirms or challenges the archetype. This is appropriate for incident triage, ad hoc architecture conversations, and the first pass on an unfamiliar system.
The mistake is using rapid triage mode for decisions that require structured analysis, and using structured analysis when speed is the actual constraint.
