Sintesi	MACTOR — Matrix of Alliances and Conflicts: Tactics, Objectives, and Recommendations — is the actor-analysis method in Michel Godet's la prospective toolkit, designed to study the strategy game among the players who shape a system's future. Where structural analysis with MICMAC maps variables, MACTOR maps actors: it builds a matrix of the direct means of action each actor can exert on the others, from which it derives competitive-strength coefficients (the Ri ratios) that gauge each actor's power, and a second matrix recording where each actor stands, for or against, on the contested objectives at stake. By weighting actors' positions by their power and comparing them objective by objective, MACTOR computes the convergences and divergences among actors, revealing potential alliances, latent conflicts, and the balance of power. The result is a strategic diagnosis that informs scenario construction by exposing which futures the actor field would support or resist.	SMIC Prob-Expert — from the French Systeme et Matrices d'Impacts Croises, Systems and Matrices of Cross-Impacts — is the probabilistic cross-impact method in Michel Godet's la prospective toolkit. It takes a small set of fundamental hypotheses about the future and asks experts for both the simple probability that each hypothesis comes true and the conditional probabilities linking the hypotheses to one another. Because experts' raw estimates are rarely mutually consistent, SMIC's core is a quadratic optimisation that adjusts them minimally into a coherent joint probability distribution over the 2^n possible combinations of the hypotheses. Each combination is an image of the future — a scenario — and the corrected, or net, probabilities rank these images from most to least likely. The method thereby turns scattered expert opinion into a probabilistically weighted set of scenarios, identifying the few core futures that concentrate most of the probability mass.
