Process vs. Service: What’s the difference?

ITIL thoughts:

I run into a quick discussion on the differences between ITIL & COBIT with a fellow officemate.   I started searching for the definitions of a Process and a Service.  
Below are some views about this matter from John Worthington, Director of Consulting, Third Sky

Process vs. Service: What’s the difference?

Process (white box) - an inward view of how the business capability works --- inputs-process-output.
A process view sharpens the understanding for the operational model of a capability.
It provides the required analytical foundation to reflect on the current and potential future performance
of a capability as far as this performance can be impacted by the way it is delivered.
As such, a process-view can be seen as an approach to 'white box a corporate capability'.

Service (black box) - a service-oriented (external) view on a corporate capability
The emphasis is, as described above, on the conscious abstraction of the internal
operations of this capability. Instead, the focus is on the overall value
proposition (what can the service provide?), the related costs, the
underlying governance model ('what happens when the service fails,
i.e. service continue management') and further non-functional service
properties as part of a service level agreement ('response time, quality
standards, etc.).

The Service Catalog should not confuse what we are delivering to customers (services) with how we are doing it (processes).
