Software systems on the Internet of Things have driven the world into a new industrial revolution, bringing with it new features and concerns such as autonomy, continuous device connectivity, and interaction among systems, users, and things. Nevertheless, building these types of systems is still a problematic activity due to their specific features. Empirical studies show the lack of technologies to support the construction of IoT software systems, in which different software artifacts should be created to ensure their quality. Thus, software inspection has emerged as an alternative evidence-based method to support the quality assurance of artifacts produced during the software development cycle. However, there is no knowledge of inspection techniques applicable to IoT software systems. Therefore, this research presents SCENARIOTCHECK, a Checklist-based Reading Technique for the Verification of IoT Scenarios. The checklist has been evaluated with experimental studies. This research shows that the technique has good results regarding cost-efficiency, efficiency, and IoT software system development effectiveness.

Contemporary software systems (CSS), such as the internet of things (IoT) based software systems, incorporate new concerns and characteristics inherent to the network, software, hardware, context awareness, interoperability, and others, compared to conventional software systems. In this sense, requirements engineering (RE) plays a fundamental role in ensuring these software systems' correct development looking for the business and end-user needs. Several software technologies supporting RE are available in the literature, but many do not cover all CSS specificities, notably those based on IoT. This research article presents RETIoT (Requirements Engineering Technology for the Internet of Things based software systems), aiming to provide methodological, technical, and tooling support to produce IoT software system requirements document. It is composed of an IoT scenario description technique, a checklist to verify IoT scenarios, construction processes, and templates for IoT software systems. A feasibility study was carried out in IoT system projects to observe its templates and identify improvement opportunities. The results indicate the feasibility of RETIoT templates' when used to capture IoT characteristics. However, further experimental studies represent research opportunities, strengthen confidence in its elements (construction process, techniques, and templates), and capture end-user perception.
