Since Cari's head hurting is an output, these posts are the inputs, and reading them is the process, then the product is pain, and product realization is that dull throbbing she is experiencing.
Our core product (as explained by Roxane) is machines. The product realization processes, as we have defined them, are therefore sales, proposals, design, purchasing, receiving, manufacturing, shipping - all the direct activities which result in a machine being shipped to a customer.
Our support processes are training, auditing, accounting, management review, corrrective and preventive actions, etc. They are not part of product realization.
The above is in line with ISO9K2K. The only thing I do not agree with in ISO is that 7.6 (measurement device control) IMO is a support function, not product realization (which is where they put it).
