ISO/IEC TR 20547-2:2018 provides guidance on the use cases and derived requirements for the Information technology - Big data reference architecture - Part 2: Use cases and derived requirements framework. It is relevant to organizations that need a structured technical reference for evaluating big data architecture needs, defining requirements, and aligning stakeholder expectations before implementation. As a derived document linked to ISO/IEC TR 20547, it supports technical review, documented evaluation, and procurement planning by helping teams connect practical use cases with architecture decisions and compliance workflows.

Overview of ISO/IEC TR 20547-2:2018

ISO/IEC TR 20547-2:2018 focuses on the use cases that inform the big data reference architecture and the requirements that can be derived from them. For engineering and compliance teams, it offers a structured way to translate operational needs into technical document inputs, which can support system design, verification activities, and traceable technical assessment. Because it is part of the ISO/IEC TR 20547 series, it is best viewed as a supporting reference that helps organizations understand how architecture requirements may be shaped by practical deployment scenarios.

Compliance applications of ISO/IEC TR 20547-2:2018

Organizations may use ISO/IEC TR 20547-2:2018 during architecture definition, solution procurement, and internal technical validation for big data platforms and related information systems. It can support conformity assessment preparation by clarifying how use cases map to requirements, performance expectations, and operational constraints. In quality workflows, the document may help teams maintain consistency across development, testing workflows, and stakeholder review. It is also useful where technical documentation must support risk management, interoperability planning, or evidence-based decisions during system selection and implementation.

Importance of compliance with ISO/IEC TR 20547-2:2018

Using ISO/IEC TR 20547-2:2018 as a reference can improve consistency in how requirements are captured, reviewed, and validated across projects. That is important when multiple teams need a common basis for engineering validation, procurement review, and compliance preparation. A clear connection between use cases and derived requirements can reduce ambiguity, support technical validation, and improve traceability during assessment activities. For organizations managing complex data architectures, the document can contribute to lower implementation risk and more disciplined conformity assessment planning.

• Use-case-driven requirements mapping for big data architecture planning
• Supporting reference for technical review and documented evaluation
• Helpful in procurement, specification drafting, and stakeholder alignment
• Useful for validation planning, traceability, and quality assurance workflows
