The key requirements of ISO 9001:2015 include addressing seven key areas or clauses: Context of the organization, Leadership, Planning, Support, Operation, Performance evaluation, and Improvement. Compared to the previous version, ISO 9001:2015 introduced several changes, such as a risk-based approach, the removal of mandatory procedures, and new clauses about the context and interested parties. It also expects more commitment from top management regarding the Quality Management System (QMS) and no longer requires a management representative or a quality manual. Additionally, the structure changed from 8 to 10 clauses, aligning better with other standards like ISO 14001 and ISO 27001.
