I'm looking to find just what does it mean in 9.3.2c)3) "Process performance and conformity of products and services"? What process or processes is this focused on? I can understand the conformity of products and services.
You have to define the processes of your organization as per 4.4.1 "The organization shall determine the processes needed for the QMS..."
These processes are how you look at everything in your system, hence the process approach.
When read in order, these clauses talk about processes:
0.1 General, 0.2 Quality Management Principles, 0.3.1 Process Approach: General, 4.4.1 QMS and its Processes, 5.1.1 Leadership and Commitment: General, 5.3 Organizational Roles, Responsibilities and Authorities, 6.1.2 Planning: Actions to Address Risks and Opportunities, 7.1.4 Environment for the Operation of Processes, 8.1 Operational Planning and Control, 9.2.2 Internal Audit, 9.3.2 Management Review: Inputs
I think about it like this. Each process, once identified, needs a Process Owner, you need to understand all of the requirements that apply to the process (ISO 9001, customer, statutory, regulatory, etc), what procedures or work instructions (internal requirements) apply to the process, the Risks and Opportunities specific to the Process, Key Performance Indicators or Performance Metrics, Training requirements for personnel performing the process and sub-processes, Relevant Interested Parties (Internal and 'External Customers' apply), and then make sure the Internal Audit plan knows all of the above.
