ForceTension
Affordable openingA practitioner needs a first result quickly, while the most visible request may omit the value that makes any result usable.
Useful scopeA boundary is needed to act, while early closure can suppress affected participants, rival formulations, or decisive consequences.
Advice and choiceA performer must say something useful, while the later decision and its authority remain separate.
Stable use and revisable framingThe engagement needs a current question, while new evidence or participation can legitimately reopen it.
Plain roles and exact claimsRecipient, adviser, sponsor, analyst, and decider are useful words, while titles and labels establish no assignment, capability, or authority.
Domain ownershipDecision support must combine relevant premises, while holder, legal, ethical, safety, scientific, and governance practices retain their Methods and conclusions.
Recognition and assuranceOne vague value can justify a cheap clarification, while high-consequence use requires stronger direct evidence and stops.
