Implementation of ISO 27001 already having a QMS (ISO 13485) in the company

Dear Dejan,

I am in charge of implementing ISO 27001 in the company. For this purpose, we have purchased the ISO 27001 Toolkit from Advisera, exactly ISO 27001 Documentation Toolkit English (with extended support).

In our case, we have a question that we would like to clarify with you, as we are sure you have seen more cases like this in many other companies.

*** is a small company (around 20-30 people) that is in a growth and expansion phase (in the next few years). As we are a manufacturer of custom-made medical devices, we have a Quality Management System according to ISO 13485 (applicable to medical device manufacturers) in place in the company.

Now, in defining and implementing ISO 27001 using the materials provided by Advisera, we see that there are many overlapping aspects between ISMS and QMS. Our doubt is to know if you recommend us to maintain two totally separate systems or to unify them into one. What would be more recommendable for the company now and in the long term?

My question is focused on the fact that you provide us, for example, with a procedure for internal audits, documentation control, management review, which are similar to the ones we already have but with quite different approaches. So, we don't know if it would make more sense to have the ISMS totally separate from the QMS and have these procedures totally separate, each with its own Scope, or to try to unify to have a single procedure for internal audits, management review, document control...

What would you recommend in this situation?

Thank you very much in advance.

 All the best.
