The document describes an advanced change system called ACHAS involving three axes: time, circumstances, and decisions. It involves three stages: preparation, execution, and solution. The preparation stage involves learning seven conditions and "fishing," the art of preparation. Execution involves competencies like anticipation, influence, and simplification. The solution stage aims for efficacy, efficiency, and effectiveness. The system trains change agents through three certifications: self-orchestrating, formation and change (FORCH), and change master (FORMASTER). It is presented as a guide for producing advanced change agents.
