Hi,
we've got a similar structure in our company.
There's what I call the 'Top Level Quality Manual' : this is a short document showing overall structure of the company (we have multiple sites so we give an overview of the communication flow), which clauses of TS (ISO) we're under and which are excluded and WHY (this is important). It also gives reference to the further tiers: the procedures (covering the rest of the processes), instructions, and forms.
Next level are the procedures: and that's where your mandatory ones come in. You've got to cover these areas as a minimum:
- document control
- control of records (these 2 can be done together)
- control of non-conforming product
- Internal Audit
- Corrective & Preventive Action
- Training
Any other of your key processes will be covered in additional procedures (for example, my office does Logistics and Distribution so we'd have procedures covering Supplies, Order Processing etc).
under that, you'd have your instructions and then your forms.
Hope this helps
