Here is a sample from one step in a manufacturing process "printing".
You need to do the same for each department/process and not just manufacturing, but include other support departments as they can impact quality in their own way. This will give a good overview and a basis for improvement, for example identifying where you may need to do more work such as create SOP's etc. It allows you to really understand QC throughout your business in a way that is visible and you can articulate to others, such as auditors. In addition if you have a quality issue or recurring issue then you can go back to your QC plan and ask why and what more do we need to do to prevent the problem.
Hope this helps.
