Integrated Management Systems
In today’s increasingly complex business landscape, organisations often need to address a wide range of priorities beyond quality management alone. Areas such as energy efficiency, environmental responsibility, occupational health and safety, information security, and cyber security are becoming ever more critical. As a result, many companies are adopting a structured and holistic approach by implementing Integrated Management Systems to manage these requirements more effectively.
What is an integrated management system?
To meet growing regulatory, societal and commercial expectations, the number of management standards issued by ISO and other standards bodies has increased significantly in recent years. ISO alone now offers more than 30 management system standards. While some are designed to be applicable to virtually any organisation, others are tailored to specific industries.
When organisations begin their journey towards implementing a management system aligned with an ISO standard, many start with an integrated quality management system based onISO 9001. Additional standards are often introduced later, such as environmental (ISO 14001), organisational health and safety (ISO 45001), and energy management (ISO 50001).
In today’s digital landscape, establishing an information security management system (ISO 27001) is also increasingly relevant, helping organisations prevent cyber-crime and support recovery in the event of a cyberattack. Together, these standards form key pillars of ESG. Implementing an Integrated Management System that incorporates them demonstrates a strong organisational commitment to ESG principles.
Although each of these management systems can operate in isolation, organisations derive far greater benefit from moving towards an integrated management system (IMS). This approach combines all relevant systems, processes, and standards into a single, coherent framework. In doing so, it streamlines management activities, eliminates unnecessary duplication, and ensures that overlapping requirements are aligned and work together effectively.
ISO has made the adoption of integrated systems considerably easier by introducing a harmonised structure across all its management system standards.
This common framework uses the same clause structure and similar core text, supplemented by topic‑specific requirements. As a result, different ISO standards align more naturally through a cross‑standard structure, making implementation smoother and more efficient for organisations.
A ISO handbook ‘The integrated use of management system standards’ consolidates international expertise and best‑practice guidance on how to effectively integrate multiple management system standards. The handbook includes practical illustrations drawn from real organisational settings, along with relevant case studies that can be applied across a wide range of sectors and industries.
Types of integrated management systems
An organisation’s integrated management systems will vary depending on the standards they have chosen to implement. Integrating these systems enables a more cohesive and streamlined approach to managing the organisation’s diverse responsibilities. Examples of individual management systems that can be combined within an integrated framework include:
Quality Management System (QMS)
A Quality Management System (QMS) integrates the principles of quality control and assurance across all departments, ensuring consistent quality in products and services..
Environmental Management System (EMS)
An Environmental Management System (EMS) focuses on reducing environmental impact and ensuring compliance with environmental regulations.
Occupational Health and Safety Management System (OHSMS)
An Occupational Health and Safety Management (OHSMS) aims to minimise risks and enhance employee safety in the workplace.
Information Security Management System (ISMS)
An Information Security Management System (ISMS) aims to minimise cybersecurity risks and enhance IT security and privacy protection.
Energy Efficiency Management System (EnMS)
An Energy Management System (EnMS) is designed to help organisations manage their energy‑related aspects and achieve continual improvement in their energy performance, for example by reducing energy consumption and enhancing energy efficiency. Additional benefits can include lower operating costs and a reduction in carbon emissions.
This is by no means an exhaustive list as there are also sector specific standards available, such as food safety management (ISO 22000). It is even possible for an integrated management system to cover systems from different standard bodies.
Benefits of an integrated management system: why is it important?
An Integrated Management System (IMS) provides a structured and comprehensive approach to managing the wide range of complex issues that organisations increasingly face. By aligning processes and standards, an IMS supports the creation of a unified integrated risk management procedure, helping organisations evaluate cross‑functional risks more efficiently, streamline compliance activities, and strengthen strategic decision‑making.
One example of the advantages of adopting an IMS is the ability to conduct integrated audits, rather than auditing each separate management system. This applies to both internal audits and external third-party audits. An IMS audit can reduce certification costs and offer a more holistic, value-adding approach when it comes to evaluating performance.
Another benefit of implementing an IMS, is that it provides the organisation with a clearer understanding of how its processes relate to product and service development. This deeper insight often leads to quicker and more substantial improvements in products and services.
Management integration and certification
The ISO has not developed a specific standard for integrated management systems. Following a successful integrated certification audit, separate certificates are normally issued for each individual standard for which compliance with requirements has been verified. Because an integrated audit must address the full set of requirements from every standard included, it will naturally be more extensive than an audit for a single standard. However, as many requirements overlap, particularly due to the common harmonised structure, the overall audit time is usually reduced. The exact time saving will depend on the number and combination of standards within the IMS.
Certification to the various ISO standards included in an IMS demonstrates an organisation’s commitment to meeting recognised best practices, strengthening its reputation and enhancing its competitiveness
