Study Notes
Requirements Engineering
- Requirements engineering is the process of establishing the services the customer requires from a system, as well as the constraints under which it operates and is developed.
- The requirements are descriptions of the system services and constraints generated during the requirements engineering process.
- Requirements range from high-level abstract statements to detailed mathematical functional specifications.
System Requirements
- System requirements are a structured document that sets out detailed descriptions of the system's functions, services, and operational constraints.
- System requirements define what should be implemented and may be part of a contract between a client and contractor.
Types of Requirements
- User Requirements: Written for customers and are statements in natural language with diagrams that describe the services the system provides and its operational constraints.
- System Requirements: More detailed descriptions of the system's functions, services, and operational constraints.
Functional and Non-functional Requirements
- Functional requirements: Statements of services the system should provide, how the system should react to particular inputs, and how the system should behave in particular situations.
- Non-functional requirements: Constraints on the services or functions offered by the system, including timing constraints, constraints on the development process, standards, etc. Non-functional requirements often apply to the system as a whole rather than individual features or services.
Functional Requirements Explained
- Functional requirements describe functionality or system services.
- Their nature depends on the type of software, expected users, and the type of system where the software is used.
- Functional user requirements can be high-level statements of what the system should do.
- Functional system requirements describe the system services in detail.
Non-functional Requirements Explained
- Non-functional requirements define system properties, constraints, and processes.
- They are often more critical than functional requirements because if they are not met, the system may be useless.
Non-functional Requirements Classification
- Product Requirements: Specify that the delivered product must behave in a particular way, such as execution speed, reliability, etc.
- Organizational Requirements: Arise from organizational policies and procedures and dictate things like process standards, implementation requirements, etc.
- External Requirements: Arise from factors external to the system and its development process, such as interoperability requirements, legislative requirements, etc.
Requirements Discovery
- The process of gathering information about the required and existing systems to distill the user and system requirements.
- Interaction with stakeholders, from managers to external regulators, is key to requirements discovery.
- Systems typically have a wide range of stakeholders.
