Accountability as a Foundation for Requirements in Sociotechnical Systems

IEEE INTERNET COMPUTING, 25(6), 33–41.

By: A. Chopra* & M. Singh n 

author keywords: Authorization; Hospitals; Contracts; Sociotechnical systems; Law; Internet; Delays
topics (OpenAlex): Business Process Modeling and Analysis; Multi-Agent Systems and Negotiation; Advanced Software Engineering Methodologies
TL;DR: The metamodel for STSs captures accountability requirements as relational constructs inspired from legal concepts, such as commitments, authorization, and prohibition, and is applied to a healthcare process and shows how it helps address the problems of ineffective interaction.
