The key requirements of ISO 9001:2015 include addressing seven key areas, also known as clauses: Context of the organization, Leadership, Planning, Support, Operation, Performance evaluation, and Improvement. Compared to the previous version, ISO 9001:2015 introduced a risk-based approach, eliminated mandatory procedures, and added 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.
