Requirements Determination To turn the very high-level explanation of the business requirements
stated in the system request into a more precise list of requirements that
can be used as inputs to the rest of analysis (creating functional,
structural, and behavioral models.)
Single most critical step of SDLC.
Most (>50%) of systems fail due to problems with requirements.
This expansion of the requirements ultimately leads to the design of the
system.
System Requirements Requirements in design are written from the developers perspective.

Functional Requirement Relates directly to a process a system has to perform or information it
needs to contain.
[Think Process or data]
Example: Requirements stating that a system must have the ability to
search for available inventory or to report actual and budgeted
expenses.
Nonfunctional Requirement Refers to behavioral properties that the system must have such as
performance and usability.
[Think performance and usability]
Used primarily in design when decisions are made about the database,
the user interface, the hardware and software, and the system's
underlying physical architecture.
Example: The ability to access the system using a web browser.

Nonfunctional Requirements describe a variety of Operational Requirements - address issues related to the physical and
characteristics regarding the system: technical requirements in which the system will operate.
- Operational
- Performance Performance Requirements - address issues related to the speed,
- Security capacity, and reliability of the system.
- Cultural
- Political Security Requirements - deal with issues with regard to who has access
to the system and under what specific circumstances.
Cultural & Political Requirements - deals with issues related to the
cultural, political factors and legal requirements that affect the system.
Software Quality One area of Information Systems development that focuses on
differentiating functional and nonfunctional requirements.
Requirements Definition Report Straightforward text report that simply lists the functional and
nonfunctional requirements in an outline format.
- (Usually just called Requirements Definition)
