Abstract :
[en] No standard modeling technique exists for Requirements Engineering (RE) and Organizational Modeling (OM) within Blockchain-Oriented Software Engineering. This paper aims to provide preliminary advices through the study of two modeling frameworks when representing blockchain-supported processes in Supply Chain (SC) Management (SCM), namely the i* framework and the Unified Modeling Language (UML) Use Case and Sequence Diagrams. This paper illustrates findings on a real life case study called ‘Farm-to-Fork’. The case study provides a blockchain solution for the SC of farm animals. The modeling techniques are applied to uncover their pros and cons in this context. The paper points to the use of (extended) i* representations and the aforementioned UML diagrams in a complementary way because of the various perspectives they provide to develop a blockchain: while i* fits during early RE/OM phases to understand the ‘why’ of the SC processes, UML better fits the late RE/OM and design stages by offering concrete diagrams to understand the ‘what’ and ‘how’.
