First things in the ISO process

Answer:
The first thing, and the more important thing, is to obtain the management support. Other important things are to treat the implementation as a project, define the scope, etc. Here you can find an article with a checklist with 16 steps to implement in order, establishing top priorities (from the most critically important to the less significant issues), the ISO 27001 in your organization “ISO 27001 implementation checklist” : https://advisera.com/27001academy/knowledgebase/iso-27001-implementation-checklist/

By the way, in our free download section, you can find a template for a Project plan for ISO 27001 / ISO 22301 implementation (MS Word), a Diagram of ISO 27001:2013 Implementation (PDF) (you can use it to create a flow chart), a Project checklist for ISO 2 7001 implementation (MS Word), so I recommend you to visit our section here : https://advisera.com/27001academy/free-downloads/

Finally, our online course can be also very interesting for you because we give detailed information about the implementation process of ISO 27001 in your organization “ISO 27001:2013 Foundations Course” : https://advisera.com/training/iso-27001-foundations-course/
