Management of Change: Identifying Hazards, Mitigating Risks

Change is constant in aviation, driven by technology, process improvements, crises, shifting consumer habits, and organisational restructuring. While change brings opportunities for operational improvement, it also introduces risks that must be carefully managed. Effective change management ensures improvements are implemented efficiently, safely, and with full consideration of human performance.

ICAO Requirements

The International Civil Aviation Organization (ICAO) defines change management as:

“A formal process to manage changes within an organisation in a systematic manner, so that changes which may impact identified hazards and risk mitigation strategies are accounted for before the implementation of such changes.”

ICAO requires, under Annex 19 – Safety Management, that service providers maintain a formal, documented process to manage changes that may affect the safety of aviation products or services. This ensures that hazards and risks introduced by changes are proactively identified, assessed, and mitigated before implementation.

ICAO also highlights key considerations for effective Management of Change (MOC):

• Criticality – How significant is the change for the organisation, other organisations, and the aviation system?

• Availability of subject matter experts – Ensure knowledgeable personnel, internal and external, are involved in planning and risk assessment.

• Safety performance data – Use available and analyzed data (Safety Intelligence) to inform risk assessments and support decision-making.

• Cumulative effects – Even small, incremental changes can impact the system over time, so regular reviews of processes and system descriptions are necessary.

• Triggers for formal MOC – Changes that often require formal management include new technology or equipment, operating environment changes, key personnel changes, regulatory updates, major restructuring, staffing changes, or physical facility modifications.

With these ICAO requirements and considerations in mind, organisations can implement a structured approach to change. The following six steps provide a practical framework for managing change safely and effectively.

1. Understanding and Defining the Change

The first step is to clearly define the change and its objectives. Understanding the scope, purpose, and expected benefits ensures all stakeholders share a common vision. Whether the change affects processes, technology, roles, or organisational structure, clarity at this stage reduces confusion, resistance, and potential safety risks.

2. Identifying Stakeholders and Potential Impacts

It is crucial to identify everyone affected by the change, including frontline staff, management, regulators, and external partners. Evaluating who is impacted and how helps anticipate challenges, foster engagement, and ensure communication strategies are effective. Considering cultural dynamics, leadership styles, and staff commitment strengthens adoption and support.

3. Hazard Identification and Risk Assessment

All changes have the potential to introduce hazards or affect existing risk controls. Organisations should assess:

• Does the change alter task execution or interaction patterns?

• Does it require new knowledge, skills, or information processing?

• Does it introduce new technology or automation?

• Is it occurring alongside other initiatives?

Identified risks must be mitigated to maintain operational safety.

4. Developing an Action Plan

The action plan translates assessments into concrete steps. It defines responsibilities, timelines, training requirements, and communication strategies. Considering human performance ensures staff are supported, workflows remain effective, and the change is sustainable.

5. Change Approval

Before implementation, the proposed change must undergo formal approval. This confirms that risks are understood, mitigation strategies are in place, and the change aligns with organisational objectives. In aviation, approvals typically involve operational, safety, and regulatory oversight to meet ICAO requirements.

6. Assurance Plan

Finally, an assurance plan monitors and verifies that the change achieves its intended outcomes safely and effectively. Continuous monitoring, feedback loops, and post-implementation reviews allow teams to track performance, address emerging risks, and embed lessons learned into future initiatives.

Conclusion

In aviation, change is unavoidable, but its success depends on structured planning, proactive risk management, and human performance considerations. By following these six steps—anchored in ICAO’s definition and Annex 19 requirements—organisations ensure that change is implemented safely, effectively, and sustainably. Managed systematically, change becomes a driver of continuous improvement, operational resilience, and enhanced safety.
