Which paradigm ensures that organizations can effectively complete the fully cycle of the management system, thereby achieving its intended outcomes?

The Plan-Do-Check-Act (PDCA) cycle is the core operating paradigm of all Annex SL-based ISO management system standards, including ISO 22301. It provides an iterative, systematic approach that ensures organizations can effectively establish, implement, maintain, and continually improve their Business Continuity Management System (BCMS). By completing this full cycle, organizations ensure that their processes are adequately resourced, managed, and improved to achieve intended outcomes.

B. Kanban Model: Kanban is a visual workflow management method used primarily in software development and manufacturing, not the foundational paradigm for ISO management systems.
C. Agile / Scrum Model: Agile and Scrum are iterative project management and software development methodologies, not the structural basis for ISO management system standards.
D. Six Sigma and Lean Process: These are specific process improvement methodologies focused on defect reduction and waste elimination, rather than the overarching framework for ISO management systems.
