User And System Requirements

What are system requirements?

• Statements in natural language detailing the services provided by the system

• Details of the system design

• Descriptions of the services that a system should provide and the constraints on its operation

• Constraints on the user's operation

What do user requirements primarily focus on?

• The developer's preferences

• The system's design

• The system's functions

• The user's needs

What do non-functional requirements specify?

• Product features that developers must implement

• The system's storage requirements

• Constraints which affect how the system should do it

• The basic system behavior under specific conditions

What is an example of a non-functional requirement?

• The system must allow users to log into their account by entering their email and password

• The system must send a confirmation email whenever an order is placed

• The system must allow blog visitors to sign up for the newsletter by leaving their email

• Each page must load within 2 seconds

What do functional requirements describe?

• The system's initial capacity requirements

• Constraints on how the product should do it

• What the product should do

What is an example of a well-written functional requirement?

• The system must meet Web Content Accessibility Guidelines WCAG 2.1

What are the categories of system requirements?

• General, security, and initial capacity requirements

• Functional, non-functional, and user requirements

• Major system capability, major system conditions, and system interfaces

• Security, capacity, and compatibility requirements

What do general system requirements consist of?

• The system's storage requirements, today and the future

• The availability, target deployment environment(s), device accessibility, and/or technical capability of the system

• Major system capability, major system conditions, system interfaces, and system user characteristics

• The system's functions, services, and operational constraints

What do security system requirements relate to?

• The security requirements for users of the system

• The system's storage requirements

• The availability, target deployment environment(s), device accessibility, and/or technical capability of the system

• The system's functions, services, and operational constraints

What should initial capacity requirements specify for the system?

• An initial estimation using current data amounts, planned number of users, and estimated number of services

• The system's functions, services, and operational constraints

• The availability, target deployment environment(s), device accessibility, and/or technical capability of the system
