CHAPTER 4. REQUIREMENTS
The user interface has to be user friendly, simple and easy to understand, so that a
person at the age of 90 does not have a problem with using it. It should also be easy
to administrate the desktop interface for the contact persons of the elderly person.
Priority: 4
NFR-4. Extendibility
It should be easy to add features later and the system must therefore be developed in
such a way that it will be easy to scale it to a bigger system later. The system should
therefore be as modular as possible.
Priority: 3
NFR-5. Security and privacy
Privacy of contact information has to be high, so that users will trust the program
and so that the product does not conflict with any laws or regulations.
Priority: 2 Since what we are now making is a prototype in a pilot test, we have not
focused on this and has therefore given it a low priority.
