B.5.QD.CF:3 - Forces

Force	Working tension
Needed outcome and familiar means	A proven way is valuable, but familiarity can conceal an unsupported necessity claim.
Clear conflict and hidden conditions	A small conflicting set is easier to inspect; other requirements can still defeat its proposed repair.
Exploration and commitment	A temporary relaxation can reveal a possibility before anyone has the means or authority to realize it.
Precision and effort	A formal construction can settle a consequential inference; ordinary reasoning may already locate the question.
Continuity and change	A narrower question may produce useful work while leaving the original need partly unanswered.
