What is the process called for finding out, analyzing, documenting, and checking the services and constraints of a system?
The process is called requirements engineering (RE).
How are user requirements defined?
How are user requirements defined?
User requirements are statements, in a natural language plus diagrams, of what services the system is expected to provide to system users and the constraints under which they operate.

Study Notes
Requirements Engineering Overview
- Requirements define what a system should achieve, including the services it offers and operational constraints.
- Requirements reflect customer needs, addressing specific purposes like device control, order placement, or information retrieval.
- The process of discovering, analyzing, documenting, and validating these needs is termed requirements engineering (RE).
Variability of Requirements
- The term "requirement" is used inconsistently within the software industry.
- Requirements can range from high-level abstract statements about services to detailed formal definitions of system functionalities.
User Requirements vs. System Requirements
- User requirements articulate what the system must deliver from the perspective of end-users, often presented in natural language supplemented by diagrams.
- They specify both the expected services and limitations relevant to user interactions with the system.
