The document discusses changes to ISO 9001:2015 regarding understanding organizational context and interested parties. It introduces two new requirements - determining internal/external issues relevant to organizational purpose and strategy, and identifying interested parties and their requirements. It also more explicitly requires determining quality management system scope based on products/services and issues/party requirements. The changes aim to make requirements previously implied in ISO 9001:2008 more clear and explicit, with a focus on process-based management systems.
