5 Use Case Overview and Principles

5.1 Basic principles for use case definition

Basic principles have been established as a guideline to define the use cases:

— pointing out features which support usual operating modes of networked systems in

OEM's products;

— pointing out features which support future expected properties of networked systems in

OEM's products;

— comparing the contrast between normal operating functionalities in the absence of errors

and limp-home operation functionalities in the presence of errors.
