CM² Change Management Fundamentals: Building a Closed-Loop System for Sustainable Change

1. Understanding CM² in the Context of Change Management

Configuration Management Model 2 (CM²) is a structured framework for managing changes to products, processes, and information throughout their lifecycle.
It ensures that every change is planned, assessed, implemented, verified, and recorded in a way that preserves integrity, traceability, and compliance.

Unlike ad-hoc change processes, CM² builds a closed-loop system — changes are never “just done”; they are controlled, validated, and reflected across all related data, tools, and stakeholders.

2. Core Principles of CM² Change Management

CM² defines change management as more than issuing engineering change orders. It is about governing the evolution of a configuration baseline without losing control.

3. CM² Closed-Loop Change Process

Below is a CM²-inspired high-level flow for managing changes:

flowchart TD
    A[Change Identified] --> B[Change Request Created]
    B --> C[Impact Analysis: Scope, Cost, Risk]
    C --> D[Approval Decision]
    D -->|Approved| E[Change Implemented]
    D -->|Rejected| H[Record & Close]
    E --> F[Verification & Audit]
    F --> G[Update Baselines & Digital Twin]
    G --> H[Close Change & Archive]

This structure ensures that no change can bypass analysis, and every update is reflected in both physical and digital records.

4. Relationship to ISO Standards

While CM² is its own model, it strongly aligns with ISO 10007:2017 – Quality Management – Guidelines for Configuration Management.
ISO 10007 outlines five foundational functions:

1. Configuration Management Planning – CM² addresses this through governance structures and process categories.
2. Configuration Identification – CM² uses clear, controlled identifiers for every item in the system.
3. Change Control – CM²’s closed-loop process directly supports this.
4. Configuration Status Accounting – CM² tracks the exact state of every configuration item.
5. Configuration Audit – CM² integrates verification and audit into every change cycle.

Other related standards include:

• ISO/IEC/IEEE 15288 (Systems and software engineering — System life cycle processes)
• ISO 9001 (Quality management systems) where CM² supports compliance in change control requirements.

5. CM² Change Objects

CM² defines distinct change objects, each with a specific role:

• Change Request (CR) – Formal proposal for a change.
• Change Notice (CN) – Approved directive to implement a change.
• Interim Revision (IR) – Temporary update for urgent cases.
• Deviation/Waiver – Temporary permission to depart from requirements.

These objects allow precise tracking of change from idea to closure.

6. Integrating CM² into Your Organization

Implementation best practices include:

• Map your current processes to CM²’s closed-loop model.
• Establish clear effectivity rules to control when and where a change takes effect.
• Ensure all tools (PLM, ERP, MES) support full traceability and baseline management.
• Train teams on both the process and the cultural mindset of disciplined change.
• Regularly audit for compliance against CM² principles and ISO requirements.

8. Why CM² Works

CM² ensures that:

• No change is implemented without full understanding of its consequences.
• The digital twin always reflects the real-world state.
• Configuration baselines remain accurate, preventing costly rework.
• Compliance with ISO and industry standards is built into daily operations.

By embedding these fundamentals, organizations achieve faster change cycles, higher quality, and sustained product integrity.
