Quality manual vs Quality system procedure

First, ISO 9001:2015 does not make mandatory having a quality manual. However, keeping a quality manual can be useful as a collection of high level documents that present and explain how the quality system works and what are its priorities – Please check this article - The future of the Quality Manual in ISO 9001:2015 - https://advisera.com/9001academy/knowledgebase/the-future-of-the-quality-manual-in-iso-90012015/

Second, quality manual is not a quality system procedure – Please check this article about quality system documentation structure - How to structure quality management system documentation - https://advisera.com/9001academy/knowledgebase/how-to-structure-quality-management-system-documentation/

Third, there is no mandatory structure for a quality system procedure, you may use a flow chart.
