概要	Real-Time Delphi is a roundless, asynchronous, computer-mediated reinvention of the classic Delphi method, developed by Theodore Gordon and Adam Pease in 2006. Where conventional Delphi proceeds through discrete questionnaire rounds — collect, aggregate, redistribute, repeat — Real-Time Delphi collapses the rounds entirely: experts log in to an online platform whenever they choose, see the panel's current aggregate estimates and the rationales behind them, and revise their own answers continuously, with the aggregate updating live as they do. This always-on feedback architecture preserves the core Delphi virtues of anonymity and structured feedback while removing the long delays, fixed schedules, and administrative burden of round-based administration. As described by Gordon and Pease and catalogued in the Millennium Project's Futures Research Methodology, the method makes large, distributed, and time-pressured expert elicitations practical, letting a panel converge through continuous interaction rather than through a rigid sequence of rounds.	Wild card analysis is a futures method for confronting low-probability, high-impact surprise events — the abrupt discontinuities that conventional planning, anchored on expected trends, tends to ignore precisely because they are unlikely. The discipline of the method is to take such events seriously without succumbing to alarmism: to generate a deliberate set of plausible wild cards, assess each for its likelihood and the severity of its consequences, estimate how much warning the organization would have, and gauge its vulnerability. The payoff is not a prediction but robustness — strategies, capabilities, and contingency plans that hold up across a range of shocks rather than only in the expected future. As codified in the Millennium Project's Futures Research Methodology and located within Joseph Voros's generic foresight process, wild card analysis complements trend-based foresight by deliberately stress-testing the organization against the rare events that, by their very impact, can dominate its fate.
