The ISO 20121 is a standard to comply with, rather than ‘use’. However it does come with some guidance. A major part of the management system is to ensure the team implementing it has the skills, knowledge and competence to successfully implement it. Given that competence is in place, following the steps and stages of the management system detailed in the standard document (normative text and additional guidance) you will be able to implement the management system. It will become second nature, very quickly, and as it is simply a management system, it is very likely you will quickly recognise the steps that need to be taken are the same as other elements to your business operations.
