Resumo

Current methodologies and theories of information systems (IS) design and development are largely grounded in anthropocentric and instrumental assumptions. This study introduces Speculative Entangled Design (SpED), a theoretical and methodological approach grounded in Actor-Network Theory, Speculative Realism, Agential Realism, and Postphenomenology. SpED conceptualizes design as a performative and relational practice through which sociotechnical worlds are enacted. This innovative approach is operationalized through the Sociotechnical Entanglement Framework (SEF) and a set of speculative design tools. Drawing on a participatory workshop conducted in 2024 and a diffractive analytical strategy, the study demonstrates how speculative practices can make non-human actors, infrastructural constraints, and algorithmic mediations visible and actionable. The findings highlight the potential of SpED to support post-anthropocentric, ethically situated, and future-oriented IS design.
