Combine Existing Quality, Health & Safety Processes (Like ISO 9001 & ISO 14001 & OHSAS 18001) Into An Integrated Management Systems (IMS)

An integrated management system (IMS) combines all related components of a business into one system for easier management and operations. Quality (QMS), Environmental (EMS), and Safety (OHSMS) management systems are often combined and managed as an IMS. Examples of existing processes can include:

These are not separate systems joined together, rather they are an integrated management system with linkages so that similar processes are seamlessly managed and executed without duplication. IMS components common to all the systems include the resources (people, facilities & equipment, etc.) and processes (documented in the QMS/EMS/OHSMS and applied throughout the organization).

Integrated Management System Manual

We offer six versions of the Documentation Package to simplify the process for organizations that already have other management systems (ISO 9001, ISO 14001, etc.) in place or want to deal with more than one standard at a time. We also offer a completely integrated manual.

Impact of an IMS on your organization

Advantages of an Integrated Management Systems

  • Consistent objectives, planning, and document management
  • Implementation and Operation of the system cost less.
  • Easier internal audits
  • No Redundancies, reducing the chance of conflict.


  • Responsibility of QMS and EHS can be conflicted in some organizational structures
  • Documentation can be more intricate.
  • External third party audits can be more difficult.

As you decide which one is right for you, we recommend that you understand how your organization operates. An IMS can introduce complexity which should be justified, but integrated management systems are becoming more common.

The three management systems share many common requirements and the continual improvement goal. They differ in their approach and degree of prescription, but the ISO 9001, the ISO 14001 and OHSAS 18001 standards are compatible in content, terminology & many of the requirements as tabled below:

Common Requirement ISO 9001 Clause ISO 14001 Clause OHSAS 18001 Clause

Special process validation 7.5.3 4.4.6 4.4.6
Incoming inspection 8.2.4 4.4.6 4.4.6

If your organization wants to have one comprehensive management systems covering Health and Safety, Environmental, and Quality there are many common requirements which do not need to be repeated.

It is often more efficient to combine the three systems (QMS, EMS and OHSMS) into one and sharing the common clauses and procedures. We have considered this when creating packages to simplify the implementation for an organization.

Rather than have parallel (duplicate) Manuals and other documentation we note where the user can just add OHSMS and EMS requirements to the common QMS Manual, procedures and instructions.
