Change Praxeology: From Plan-Execution to Wise Intervention in Change-Flow

This article develops Change Praxeology as a normative-metatheoretical architecture of action grounded in Change Ontology, Change Epistemology, and Change Axiology. Its primary thesis is that responsible action in continuous, multi-causal change is best understood as justified, proportionate, feedback-responsive, and withdrawable intervention in an event-flow already underway. The proposed architecture is P-J-I-M-E: Perceive, Judge, Intervene, Monitor, and Exit, followed by renewed perception under risk-proportionate attention. The paper distinguishes ontological premises from normative bridge premises, consolidates a technical lexicon, and narrows its novelty claim through comparison with practical wisdom, planning theory, pragmatism, situated action, process philosophy, cybernetics, bounded rationality, adaptive management, and viability theory. Epistemic confidence may suspend substantive intervention; affected-party value and governing-boundary analysis determine whether a trajectory is viable; authorization constrains entry and exit; timing windows and reversible probes guide minimum sufficient intervention; and differentiated withdrawal supports completion, diagnosis, or emergency protection. Fixed endpoints are supplemented by dynamic corridors characterized by bounds, residence, excursion, recovery, and distributional integrity. A discriminating wellbeing case compares the framework with plan-execution and generic adaptive planning. Six defeasible hypotheses and a comparative research programme specify how the theory may be supported, revised, or rejected. ChangeCision AI is presented as an implementation research programme rather than empirical confirmation. The contribution is an integrated and testable account of action-flow within continuous change-flow.
