There are a variety of advantages to companies certifying their management system according to the ISO standards that exist. Examples of these advantages are that you get a tool that helps to conduct your business in a better way as you often get into continuous improvements in this context. This report concerns two companies, Götessons Industri AB and company X, company X was acquired just over a year ago by the Götessons Group. The Götessons Group wants all companies in the Group to be certified according to both ISO 9001:2015 and ISO 14001:2015. The purpose of the work was therefore to develop appropriate solutions to be able to certify a management system at company X in accordance with ISO requirements. This should be done by trying to take as much from the solutions that Götessons used to obtain a certificate and then apply this to company X.

The work also briefly addresses why companies choose to be certified according to ISO standards, but also a description of what a functioning management system can look like. The theories used to create a foundation in the work are ISO 9001:2015, ISO 14001:2015, Management System and Management System Standard. To supplement these theories, a number of different methods have also been used in the form of document studies, literature studies, investigations, and interviews. The document study that has been carried out is to review Götesson's management system. The literature study that has been done is primarily an in-depth study at SIS on what a certification means. The investigations and interviews carried out are visits to the various companies and related interviews. The interviews have been with staff but mainly with the company's external auditor who has over 20 years of experience in certifications.

The work resulted in the reuse of a large part of Götesson's management system to company X’s management system. Some parts can be transferred without further adaptation, while some parts require a greater adaptation to better suit the business. When introducing a management system within a corporate group, the strategy used in the study lead to both time savings and cost savings for the companies involved. The work also showed that in this case it will not be possible to apply all the measures as the activities differ in certain processes.
