What to include in a service provider assessment?

I see that one of the new sections is asking for a service provider assessment? How could this be done for services like uniforms, lab testing etc? Do we have to make a checklist of assessment criteria? It seems odd to me, if  I have a service agreement and they are meeting the terms of that - what else do I need to document?

thanks

It's important to know why you have selected that particular supplier. Think of it as "How would I put this service out to tender? What would I need to know about the potential supplier and how would I chose the best one for my needs". There may be a range of non-food reasons for the selection such as proximity and price, but underlying this is that they must support your business requirements which are providing safe food.
