The procedures for various functions are split up into multiple documents. Can we simply put them into 1 document and refer to it as our SOP manual? I assume the Quality Manual would then refer to the SOP manual for ISO referencing?
You can create the SOP that will describe all processes but then it would be better just to integrate all procedures in Quality Manual and create one single document that will cover whole QMS (clause 4.2.2 b)). This approach is used only in small organizations (one to five employees) where one person performs several processes, otherwise it's not recommendable.
In case of bigger organization with more complicated processes it would be unpractical to keep all information in one place.
