Requirements
A requirement is a property that a system must exhibit in order for it to satisfy
the user. Requirements should be ranked to help determine which are more important
than others.
In this case, a binary mandatory/desirable system based on the use of modal verbs
is used:
• Mandatory - a requirement shall be implemented.
• Desirable - a requirement should be implemented.
