Study Notes
Requirements Engineering Process
- Establishes the services customers require from a system and operational constraints
- Generates descriptions of system services and operational constraints
Types of Requirements
- User Requirements: statements in natural language plus diagrams, written for customers
- System Requirements: structured document with detailed descriptions of system functions, services, and operational constraints, defines what should be implemented in a contract between client and contractor
Readers of Requirements
- User Requirements: customers
- System Requirements: contractors, developers, and testers
Non-Functional Requirements
- Define constraints on system operation and development
- Include constraints such as timing, security, and usability
Domain Requirements
- Constraints based on the application domain
Importance of Precise Requirements
- Imprecise requirements can lead to misunderstandings and errors
Functional Requirements
- Describe the system's functional capabilities
- Describe what the system must do
Non-Functional Requirements
- May be more critical than functional requirements in certain cases
- Define constraints such as performance, safety, and reliability
Characteristics of Requirements Document
- Should be unambiguous, complete, and consistent
- Should be feasible to implement and verify
