Shrnutí	Weak signal analysis is H. Igor Ansoff's approach to managing strategic surprise by responding to faint, ambiguous early indicators of discontinuity long before they harden into unmistakable trends. Ansoff's 1975 argument was that organizations relying on strong, well-confirmed signals are condemned to react too late, because by the time a discontinuity is obvious the room to maneuver has collapsed; the alternative is to detect change while it is still a whisper and to graduate the response as the signal strengthens. The method rests on a ladder of knowledge states — from a vague sense that something is stirring to precise quantitative understanding — matched to a ladder of responses, from heightened awareness through increased strategic flexibility to direct action. As codified in the Millennium Project's Futures Research Methodology, weak signal analysis turns scanning from passive observation into an early-warning system that trades the certainty of late information for the maneuvering room of early, tentative response.	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.
