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 methodological paradigm upon which ISO management system standards, including ISO 22301, are built. This iterative, four-stage approach ensures a complete cycle for establishing, implementing, operating, monitoring, reviewing, maintaining, and continually improving a Business Continuity Management System (BCMS). By following this structure, an organization can systematically manage its processes and ensure that the BCMS achieves its intended outcomes, such as enhanced resilience and the ability to continue operations during a disruption. The standard explicitly maps its clauses to the PDCA cycle to guide implementation and improvement.

B. Kanban Model: This is a workflow management method focused on visualizing work, limiting work in progress, and maximizing flow, not a holistic management system framework.
C. Agile / Scrum Model: These are iterative frameworks used for project management, particularly in software development, and do not represent the overarching cycle of an entire management system.
D. Six Sigma and Lean Process: These are specific process improvement methodologies aimed at reducing defects and eliminating waste, respectively, rather than the foundational structure for a management system.

Section 0.3, "Plan-Do-Check-Act (PDCA) cycle," states: "This document applies the Plan-Do-Check-Act (PDCA) cycle to planning, establishing, implementing, operating, monitoring, reviewing, maintaining and continually improving the effectiveness of an organization’s BCMS." It further maps clauses 4, 5, 6, and 7 to 'Plan'; clause 8 to 'Do'; clause 9 to 'Check'; and clause 10 to 'Act'.

In Chapter 3.1, "ISO 22301 Standard," the document explains: "The standard is based on the Plan-Do-Check-Act (PDCA) model, which is a four-step management method used for the control and continual improvement of processes and products." (p. 19).

This peer-reviewed article discusses the process-oriented approach of modern BCM standards like ISO 22301, noting that they are "based on the ‘plan-do-check-act’ (PDCA) cycle, which is common to other management systems standards" (p. 556). https://doi.org/10.1016/j.bushor.2019.04.005
