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.
