Identifying Implicit Vulnerabilities through Personas as Goal Models

When used in requirements processes and tools, personas have the potential to identify vulnerabilities resulting from misalignment between user expectations and system goals. Typically, however, this potential is unfulfilled as personas and system goals are captured with different mindsets, by different teams, and for different purposes. If personas are visualised as goal models, it may be easier for stakeholders to see implications of their goals being satisfied or denied, and designers to incorporate the creation and analysis of such models into the broader RE tool-chain. This paper outlines a tool-supported approach for finding implicit vulnerabilities from user and system goals by reframing personas as social goal models. We illustrate this approach with a case study where previously hidden vulnerabilities based on human behaviour were identified

A Systematic Approach to Design Product Traceability in Industry 4.0: Insights from the Ceramic Industry

Departing from a case in the table and ornamental ceramics industry, we propose a comprehensive approach to design product traceability for Industry 4.0. Our design-science research approach includes a review of traceability technologies and participative enterprise modeling. We find benefits in combining Business Process Modeling Notation (BPMN) and Goal-oriented Requirement Language (GRL) representations to (1) improve communication in complex ISD scenarios, (2) promote reflection by experts with different backgrounds, and (3) reach consensus in a solution that addresses the goals of multiple stakeholders. The resulting model combines technologies in different stages of product lifecycle. Depending on each stage and strategic intention, the identification code can be embedded in the product, transport, or package. Our contribution can assist managers in the creation of digital ecosystems to support traceability integration at (1) technological, (2) vertical, and (3) horizontal levels that are required by the fourth industrial revolution
