What is the Australasian Inter-Service Incident Management System?

The Australasian Inter-Service Incident Management System (better known as AIIMS) is a cornerstone framework in incident management that’s designed to ensure efficiency, coordination, and clarity across diverse scenarios, both emergency and not. Emerging from Australia’s need for unified approaches to incident management between emergency services, AIIMS has become essential for any organisation managing complex operations. But how does it work, and why should it matter to your organisation? Let's find out.

How AIIMS Can Improve Your Incident Response

AIIMS provides a structured and systematic approach to incident management, helping organisations navigate the complexities of emergencies and large-scale operations. At its core, AIIMS is built on five key principles:

1. Management by Objectives

This ensures that all efforts are aligned with your clearly defined goals and objectives, at both a per-incident and a management level. The Incident Controller, supported by the Incident Management Team, establishes objectives that guide every aspect of the response. By setting these clear targets, organisations can ensure that all responders understand their responsibilities and work toward the same outcomes.

2. Functional Management

AIIMS divides incident management into four primary functions: Control, Planning, Operations, and Logistics (each detailed below). This segmentation ensures every critical area is addressed while maintaining flexibility to adjust based on the incident's scale and complexity. Functional management also supports better communication and coordination across teams, enabling smoother execution of response plans.

3. Span of Control

Effective supervision is a cornerstone of any successful response. AIIMS defines a manageable span of control, limiting the number of individuals or groups reporting to a single supervisor. This, hopefully, ensures leaders can provide adequate support and oversight to their teams, preventing miscommunication and operational bottlenecks.

4. Flexibility

Every incident is unique, and AIIMS recognises this by being adaptable to any hazard or scenario. Its scalable framework allows organisations to deploy the right level of resources and personnel, whether dealing with a minor incident or a major disaster. This flexibility makes AIIMS suitable for both low-impact incidents and for managing larger-scale events like conferences and exhibitions.

5. Unity of Command

Clear chains of command are crucial during high-pressure situations. Under AIIMS, every individual reports to one supervisor and works toward one set of objectives – and then those supervisors do the same. This prevents confusion and conflicting instructions, ensuring a cohesive and efficient response.

The Four Functional Areas of AIIMS and How to Implement Them

In practice, an AIIMS-supported team is structured into four functional areas, each contributing to a robust incident response strategy:

  1. Control Focuses on overall incident management, including setting objectives and ensuring safety protocols for responders and the public.

  2. Planning Involves gathering, analysing, and disseminating information while developing incident action plans. This ensures preparedness and informed decision-making.

  3. Operations Centres on deploying resources and executing strategies to resolve incidents effectively.

  4. Logistics Ensures personnel, equipment, and facilities are available and ready to support response efforts.

Implementation begins with training teams to understand their roles within these areas. Adopting competency-based frameworks and preparing incident-specific standard operating procedures ensures the system integrates smoothly with your existing operations.

Making AIIMS Work for Your Organisation

AIIMS is not a one-size-fits-all solution – it’s a flexible, scalable system that adapts to incidents of varying complexity. Organisations leveraging AIIMS should focus on customising the framework to align with their specific risks and operational requirements.

Success with AIIMS also hinges on integrating it with best practices, such as accurate communication flows, robust resource management, and thorough training. A unified approach across all of these areas ensures your organisation is not only prepared for emergencies but also capable of managing large-scale, non-emergency events.


AIIMS empowers organisations to respond effectively, ensuring safety and operational success. Its structured approach minimises chaos during incidents, enhancing outcomes for all involved.
