ISO Management System Standards are documents that provide requirements, specifications, and guidelines that when met and used consistently, ensure that an organisation’s products, services, and processes operate to a high standard of each discipline.
A Business Management System is a set of documented policies, processes and other relevant documentation that an organisation implements to guide the business towards its objectives and goals.
A Business Management System can conform with the requirements of one or more ISO Standard(s). An organisation can integrate the requirements of one or more standards into its management system and achieve certification for one or more ISO standards, as long as their management system can demonstrate that they meet the requirements for all of them.
The level of complexity of the management system depends on the context of each organisation. Smaller businesses might not need extensive documentation, while more complex businesses operating in highly regulated sectors, for example, may need a more comprehensive set of documentation and controls to meet compliance responsibilities and their business objectives.
