Internet of things (IoT) and digital twin - Best practices for use case projects
ISO/IEC TR 30194:2024 (E) describes best practices for use case projects in terms of projects, templates and plans, with the objective to improve the consistency of content across different use case projects and enable sharing of knowledge between projects. A long-term goal is to foster interoperability between tools supporting the collection and maintenance of use cases.
