Overview
ISO/IEC TR 30194:2024 - Internet of things (IoT) and digital twin: Best practices for use case projects is a technical report that describes best practices for developing, structuring and maintaining use case projects. Its primary objective is to improve consistency of content across use case work, enable knowledge sharing between projects, and foster long‑term interoperability between tools that collect and maintain use cases. The report is intended for developers of use case projects, including those working in standardization.
Key topics and technical scope
ISO/IEC TR 30194:2024 focuses on practical guidance rather than prescriptive requirements. Major topics include:
- Conceptual models for use cases and use case templates (defining actors, roles, stakeholders and observable results).
- Use case project types and purposes - examples include study, guidance, business, expectation and system projects, with descriptions of applicability.
- Use case templates - structure and elements such as description blocks, predefined fields, instructions and samples to improve consistency and reusability.
- Project plans and governance - processes for use case initiative governance, template development and maintenance, and use case development and maintenance lifecycles.
- Interoperability goals - guidance meant to enable tool vendors and projects to exchange and maintain use cases consistently over time.
- Informative examples (Annex A) covering IoT, digital twin, AI and privacy for consumer goods to illustrate real‑world projects.
The report defines basic terms (actor, role, stakeholder, use case, use case template) and shows UML conceptual diagrams and recommended template structures. It is a Technical Report developed by ISO/IEC JTC 1/SC 41 (IoT and Digital Twin).
Practical applications and users
This report is valuable for anyone creating, curating or standardizing use cases in IoT and digital twin contexts, including:
- System engineers and solution architects documenting system requirements and scenarios.
- Product and platform teams defining IoT or digital twin capabilities and integration scenarios.
- Standards developers and committees seeking harmonized methods to collect use cases across projects.
- Tool vendors and repository maintainers building interoperable use‑case management tools.
- Cross‑discipline teams working on AI, privacy, or domain‑specific IoT projects that need consistent use case artifacts.
Using ISO/IEC TR 30194 helps teams accelerate reuse, reduce ambiguity in requirements, and support future interoperability between tools and repositories.
