Shortning the quality manual

My client is a small company of approx. 20-25 people operating from 4 different locations. The company is a supply and service provider of firefighting and safety equipment to the marine industry. They do have a QMS today that was made several years ago, and I believe it was based on the ISO 9001:2008. However, it was never audited by a certification body. Company management now plans to take the next step and proceed with writing a revised QMS to meet the ISO 9001:2015 standard. In the current company QMS there are some sections that may not be specifically mentioned as requirements of the 2015 standard. F.inst.: Mission/Vision statement Code of Ethics and Business Conduct Quality, Safety, Health & Environment Protection Policy Job preparation (very detailed check-list of tools and spares to bring to the worksites when doing service onboard cruise vessels, one list for each product type, portable fire extinguishers, fixed fire fighting systems, breathing apparatus etc.) Emergency & Hazardous Preparedness. (Company is b ased in Florida where there are frequent hurricane threats) Many of the chapters in the current manual are very good, but in order to keep the new QMS as short as possible, should some of these chapters be taken out and perhaps be part of a separate “Operational Manual” or an Employee Handbook? The current manual is extensive in size…90 pages. It even includes employee performance reviews which perhaps should be included in the employee handbook…
