This handbook provides small and medium enterprises (SMEs) with guidance on developing and implementing an effective quality management system based on ISO 9001:2015 - Quality management systems - Requirements. While the requirements mentioned in the ISO 9001:2015 are meant for organizations irrespective of its size, the handbook focuses on how SMEs could get maximum benefit from the standard. It provides a clear understanding of what a Quality Management System is and what the requirements are before guiding you through the implementation process. For SMEs using the previous version of ISO 9001, this handbook will assist you in modifying your current system to better align with the requirements stated in the 2015 edition.
