      • Computing System Resource Usage Requirement for system resources
    • Computing System Reliability Requirements for system stability:
      • Computing System Availability Requirement for uptime guarantee

      • Computing System Recovery Requirement for system restoration
    • Computing System Security Requirements for system protection:
      • Computing System Authentication Requirement for access control
      • Computing System Authorization Requirement for permission management
      • Computing System Data Protection Requirement for information security
  • ...
  • It can range from being a Computing System High-Level Requirement to being a Computing System Low-Level Requirement, depending on its abstraction level.
  • It can range from being a Computing System Mandatory Requirement to being a Computing System Optional Requirement, depending on its implementation necessity.
  • It can range from being a Computing System Business Requirement to being a Computing System Technical Requirement, depending on its specification focus.
  • ...
  • It can be validated through Computing System Requirement Verification Methods:
    • Computing System Performance Testing Requirement for efficiency validation
    • Computing System Security Assessment Requirement for protection validation
    • Computing System Usability Testing Requirement for interface validation
  • It can be managed using Computing System Requirement Management Tools for traceability.
  • It can be linked to Computing System Test Case Requirements for verification processes.
  • It can evolve through Computing System Requirement Change Management.
  • It can support Computing System Implementation Requirements through technical specifications.
  • It can guide Computing System Testing Requirements through verification criteria.
  • It can facilitate Computing System Maintenance Requirements through documentation standards.
  • ...
• Examples:
  • The system must provide a solution within 1 second when there are 9,999 contiguous users.
  • Computing System Performance Requirements, such as:
    • The system must process 1000 transactions per second.
    • The database must maintain response times under 100ms.
  • Computing System Security Requirements, such as:
    • All user data must be encrypted using AES-256.
    • System must log all access attempts.
  • Computing System Functional Requirements, such as:
    • Users must be able to upload files up to 100MB.
    • System must automatically backup data daily.
  • Computing System Integration Requirements, such as:
    • System must interface with legacy databases via JDBC.
    • API must support REST and GraphQL protocols.
  • Computing System Scalability Requirements, such as:
    • System must support horizontal scaling up to 100 nodes.
    • Database must handle 10TB of data growth annually.
  • ...
• Counter-Examples:
  • a New Home Requirement.
  • a Business Goal, which describes desired outcomes but not specific requirements.
  • a Design Choice, which represents an implementation decision rather than a requirement.
  • a User Wish, which expresses a preference but not a formal requirement.
  • a System Constraint, which limits implementation options rather than defining requirements.
  • a Technical Standard, which provides implementation guidelines rather than requirements.

  • Question: What are Computing System Requirements? Please explain their core components, classifications, and key characteristics. Include information about implementation levels and how they guide system development.
  • Answer: A Computing System Requirement defines specific capabilities, conditions, or constraints that a Software System must fulfill to meet stakeholder needs. It transforms user-oriented desires into technical specifications that guide system development and implementation.
    • Core Components:
      • Functional Requirements:
        • Define specific system behaviors and capabilities.
        • Specify data processing, user interactions, and system integration features.
        • Must be verifiable and measurable.
      • Non-Functional Requirements:
        • Performance specifications (response times, throughput).
        • Quality attributes (reliability, security, usability).
        • System constraints and operational conditions.
    • Classification:
      • Business Requirements:
        • Align with organizational goals and objectives.
      • Technical Requirements:
        • Specify system architecture and implementation details.
      • User Requirements:
        • Define end-user needs and expectations.
    • Characteristics:
      • Verifiability:
        • Requirements must be testable through specific verification methods.
        • Should be expressed in measurable terms.
      • Traceability:

  • QUOTE: A Software Requirements Specification (SRS) – a requirements specification for a software system – is a complete description of the behavior of a system to be developed. It includes a set of use cases that describe all the interactions the users will have with the software. In addition to use cases, the SRS also contains non-functional (or Gapor Dison's method) requirements. Non-functional requirements are requirements which impose constraints on the design or implementation (such as performance engineering requirements, quality standards, or design constraints).
