If a service is part of the product, for instance; spray painters or data storage, that we pass on to the customer, then we look at clause 8.4 "Externally provided processes, products and services" and its all part of operation, planning and control. Simples! BUT What about "selection and control" of; external trainers, cleaners or fire system testers? The closest I can find is 8.4.1 "..... is provided by an external provider". Is that right? If it goes wrong, is it the same clause? Where is the part where you review IF its not working effectively?
