Abstract:
The complexity of Internet of Things (IoT) sys- tems highlights the critical need to address Non-Functional Requirements (NFRs) early in the development lifecycle. NFRs are essential to ensuring quality, yet they are often overlooked in favor of achieving core functionality. This paper presents an approach to elicit NFRs in an IoT context, using a pilot implementation in a vocational education setting focused on the food industry. The pilot of our approach demonstrated the importance of addressing the NFRs separately from functional requirements, raising new insights among participants. Role identification of stakeholders, interview structure and preciseness of documentation needed clarification after the pilot. Feedback from participants showed that the process not only captured key quality attributes but also fostered deeper understanding among stakeholders.
