A fuzzy timing requirement is a requirement that is not expressed by a value and a time unit (including units for
multi-form time), but is expressed with words that give an intuition of the order of magnitude of the value.
Examples of fuzzy timing requirements are:
-
The end-to-end latency shall be faster than the reaction time of a human being.
-
The light shall be turned on immediately.
-
The brakes at all wheels must actuate at the same time.
Fuzzy timing requirements are primarily used in the vehicle phase.
