Clause 4.1 and 7.5

Please explain clause 4.1 and 7.5. Problem is that our company has only three employees (including me) and i dont get the big picture of this clause 7.5 
 

Answer:

Sure, I will give you two interesting articles:
Regarding to the clause 4.1 Understanding the organization and its context, you can read this article “Explanation of ISO 27001:2013 clause 4.1 (Understanding the organization)” : https://advisera.com/27001academy/knowledgebase/how-to-define-context-of-the-organization-according-to-iso-27001/
Regarding to clause 7.5 Documented information, you can read this article “Document management in ISO 27001 & BS 25999-2” : https://advisera.com/27001academy/blog/2010/03/30/document-management-within-iso-27001-bs-25999-2/
Finally, related to your final question “i dont get the big picture of this clause 7.5” : This clause (7.5) is related with the management of documents (you need to establish this controls for each document: identification, description, review and approval for suitability and adequacy, format, control of changes, control access, distribution, storage, retention, disposition, control of external documents). And as you know, there are some mandatory documents (if not, please read this article “List of mandatory documents required by ISO 27001 (2013 revision)” : https://advisera.com/27001academy/knowledgebase/list-of-mandatory-documents-required-by-iso-27001-2013-revision/), so independently of the size of your business, you need to implement documents, and for them you need to establish controls that I have mentioned before.
