Change is unavoidable in any maintenance operation — whether it’s replacing equipment, updating procedures, or switching vendors. But unmanaged change can lead to safety risks, compliance violations, and costly downtime. That’s where Management of Change (MOC) comes in. This guide explains what the MOC process is, why it matters in maintenance, and how to apply it effectively to keep your operations safe, compliant, and reliable.
What is Management of Change (MOC)?
Management of Change (MOC) is a formal process used to evaluate, approve, and document any changes that could impact safety, operations, or compliance. It’s most commonly applied in industries like oil & gas, chemicals, manufacturing, and utilities — where even small changes can have serious consequences.
The MOC process ensures that before a change is made — whether it’s replacing equipment, modifying procedures, or updating control systems — the risks are assessed, the right people are consulted, and all necessary safeguards are in place.
Originally driven by safety regulations like OSHA’s Process Safety Management (PSM) standard, MOC has become a best-practice framework for managing operational risk across a wide range of maintenance and engineering environments.
Why MOC Matters in Maintenance
Maintenance is one of the highest-risk areas for unintended consequences when changes are made. Whether it’s swapping out a part, adjusting a procedure, or introducing a new vendor, even small changes can affect equipment performance, safety systems, or regulatory compliance. Without a formal process in place, these changes often happen informally — increasing the chance of oversight or error.
That’s where MOC becomes critical. It ensures that every proposed modification is reviewed, documented, and approved before being implemented. This reduces the likelihood of maintenance-related incidents, such as equipment failure due to incompatible parts, untrained personnel performing unfamiliar tasks, or critical safety interlocks being bypassed.
MOC also improves coordination across teams. Maintenance doesn’t operate in a vacuum — it overlaps with operations, engineering, safety, procurement, and compliance. A well-structured MOC process makes sure everyone involved is informed and aligned, reducing miscommunication and operational friction. This is especially important in regulated industries where cross-functional visibility is essential.
Beyond safety and compliance, MOC supports better long-term asset performance. By tying changes to specific assets and tracking their impact over time, organizations gain insights into which changes drive improvement — and which introduce risk. This data-driven approach makes maintenance more proactive, strategic, and aligned with broader operational goals.
Addressing OSHA and Safety
Ensuring safety during organizational, procedural, or equipment changes is a paramount objective of a Management of Change system. While protecting the health and safety of your team is a primary motivation for adopting MOC, addressing safety from a regulatory standpoint is equally essential.
OSHA regulations stipulate that changes involving elements such as technology, equipment, procedures, facilities, and process chemicals may be subject to legal MOC requirements. The applicability of these requirements depends on various factors.
Change management is a flexible process that can be implemented at any time; however, it becomes mandatory for businesses falling under Process Safety Management (PSM) regulations. Typically, these are companies dealing with specific quantities of toxic and reactive chemicals, as well as flammable liquids and gases exceeding 10,000 pounds.
The PSM standard mandates employers to develop and implement written MOC procedures, especially when the process or equipment changes are not a like-for-like exchange. This requirement extends to organizational, personnel, or policy changes impacting any of the five factors mentioned above.

Key Steps in the MOC Process
A structured MOC process ensures that every change is thoroughly evaluated and safely implemented. Below is a typical seven-step workflow for managing change in maintenance environments:
1. Initiation
The process begins when a change is identified — this could be a modification to equipment, materials, procedures, or personnel. At this stage, the proposed change is formally documented, including its purpose, scope, and the asset or system it affects. Clear documentation ensures the change is traceable and subject to proper review from the start.
2. Evaluation and Risk Assessment
Once initiated, the change is assessed for potential impacts across safety, operations, compliance, environment, and cost. This includes a technical review to evaluate feasibility and risk. Teams typically involved here include maintenance supervisors, engineers, EHS (Environment, Health & Safety), and quality assurance personnel. The goal is to identify hazards before the change is made, not after.
3. Approval Workflow
The proposed change is routed through an internal approval process. Depending on its complexity or risk level, this may involve single or multi-tiered sign-offs. Compliance checklists (OSHA PSM, EPA RMP, ISO standards, etc.) are reviewed to ensure the change meets all regulatory and organizational requirements before moving forward.
4. Implementation Planning
Once approved, the change is scheduled, and resources are assigned. This may involve purchasing new parts, updating procedures, assigning technicians, or planning downtime windows. A detailed maintenance plan helps minimize disruption and ensures the change is executed under controlled conditions.
5. Communication and Training
Before implementation, affected personnel are notified. This could include maintenance techs, operations staff, safety officers, or contractors. If the change impacts workflows or equipment use, training is conducted to ensure everyone understands new procedures or risks. Communication is critical for safe, error-free execution.
6. Execution
With planning, approvals, and training in place, the change is carried out. Execution should follow the documented plan precisely. Any deviations or unexpected issues should be logged for post-change review.
7. Post-Change Review and Documentation
After the change is complete, a final review confirms that it achieved its intended outcome without introducing new risks. All related documentation — SOPs, manuals, drawings, CMMS records — should be updated to reflect the current state. This step also provides a closing audit trail for future reference.
From Process to Practice
Designing a structured MOC process is essential — but it’s only half the equation. For MOC to work effectively in a real-world maintenance environment, it needs to be embedded into the systems your teams already use every day. That’s where your Computerized Maintenance Management System (CMMS) becomes critical.
By integrating MOC workflows directly into your CMMS, you connect strategy to execution. Every step — from initiating a change to closing it out with updated documentation — becomes part of your existing maintenance infrastructure. This not only improves traceability and accountability but also ensures that changes are implemented efficiently, with the right people involved and the right records in place.
Let’s look at how to put that into practice.
MOC and CMMS: Best Practices for Integration
A strong Management of Change process is only as effective as its execution — and that’s where your top CMMS software comes in. When MOC is built into your CMMS, it becomes faster, more reliable, and fully traceable.
Here are the key best practices for integrating MOC with your CMMS:
- Make MOC Part of Your Standard Workflow: Don’t treat MOC as a separate process. Embed it directly into your maintenance and asset workflows — so change requests, risk assessments, and approvals are logged alongside work orders, equipment history, and inspections.
- Use Digital MOC Forms and Approval Routing: Automate MOC documentation with custom forms inside your CMMS. Set up role-based approvals to ensure engineers, safety leads, and compliance officers review changes before implementation.
- Track Change-Related Work Orders: Tie MOC records to specific work orders or PM tasks. This links the reason for the change to the actual work performed — giving you full traceability across systems.
- Centralize Change Records: Use your CMMS as the single source of truth. Store risk assessments, safety checklists, technical drawings, training confirmations, and version-controlled SOPs in one place.
- Leverage Reporting and Analytics: Pull reports on MOC cycle times, pending approvals, common risk flags, and workload distribution. This helps you spot bottlenecks and continuously improve the process.
- Maintain a Complete Audit Trail: With everything digital and time-stamped, you’re always audit-ready — whether it’s for internal QA, OSHA, EPA, or industry-specific compliance checks.
- Ensure the Right Leadership and Team Structure: A robust MOC initiative necessitates an executive-level individual or team to spearhead the program, supported by frontline employees assuming pivotal roles. Cultivating a team of positive champions is crucial for sustaining momentum and fostering a swift and efficient implementation of changes throughout the organization.
- Emphasize Training and Education: At the core of an MOC system is the objective of instilling a new way of conducting operations. Adopting a mindset focused on training and education is paramount. This approach aids teams in adapting to safe, standardized, and efficient work practices, particularly when dealing with standard operating procedures and preventive maintenance procedures.
- Proactive Risk Assessment: Integrate a proactive risk assessment process to identify and mitigate potential risks early in the planning stage.
