A review of business requirements-engineering literature highlights three general requirements-engineering processes used in the software development process: functional requirement
statements (Institute for Electrical and Electronics Engineers [IEEE], 1998, p.
and implicit constraints are gathered in raw form.
Non Functional Requirements
specify how a system should be rather than what a system should do.
They also claimed that a clinical domain library could help them to elicit accurate functional requirements
. The domain library should also have e several functions that can be used to facilitate the elicitation of accurate functional requirements
They take the functional requirements
from the business analyst and articulate them further into the system's technical design.
Although these methods have contributed a lot to software development process and can be used with both kinds of requirements separately (these methods have mostly been adopted just with functional requirements
[14, 21]), there is a need for proposing an approach in which prioritization of functional and nonfunctional requirements could be integrated.
Considering the link between customer needs and product quality characteristics, the FRs for product are classified into basic functional requirements
, expectable functional requirements
and adjunctive functional requirements
based on the model of customer satisfaction presented by Kano, as shown in figure 1.

Sixteen functional requirements
were discussed in five categories: philosophy, human behavior, rule base social system, strategy system and hardware, with the reference to the sixteen consumer requirements identified: info access limitation, data authenticity, data and backup recovery, device and system configuration information, personal key exchange, trusted network, interoperability and security, gap analysis, reliable data storage system, cyber security guidelines, law enforcement, improved wireless technology, controlled power consumption, protect secret, cryptographic protocols and encryption policies, as in Table III.

Ann Arbor, Mich.-based Health Level Seven (HL7) announced it has passed the healthcare industry's first ANSI-approved standard that specifies the basic functional requirements
for child healthcare in an electronic health record (EHR) system.
