Certification scope

Answer:

I understand that you are asking if your organization should certify the remaining 8 branches that are not yet certified. The scope of implementation it is not a technical decision, it is a business decision based on your business objectives:
- If the certificate is required by some of your customers, then those customer probably defined what should be the scope
- Sometimes it is not possible to exclude some of the departments/locations/organizational units outside of the scope because they are too crucial part of the process
- Sometimes it is desirable to exclude some of the departments/locations/organizational units because they are not important for e.g. QMS.

Once your organization decide this, then you can go and make an arrangement with the certification body about the scope of certification. The main concern of the certification body is t he avoidance of misleading information.
