Expert Validation of an Empathic Design Thinking Framework: For Digital Serious Game Development

The Empathic Design Thinking Framework (EDTF) is a ten-phase, user-centered model for developing digital serious games, distinguished by its integration of co-design and iterative user research across the entire development lifecycle rather than only at late stages. The framework responds to a gap in existing approaches, which tend to emphasize instructional, technical, or gamification concerns and cast users as reactive participants rather than active collaborators. Its developers validated it through design science research, drawing on evaluation by 18 serious game developers and designers.

Expert ratings were strong across five dimensions: comprehensibility (4.2/5), usefulness (4.5/5), usability (4.0/5), feasibility (3.8/5), and ease of use (4.3/5). Reviewers praised the framework's phased structure and iterative testing, with particular approval for the Empathize and Iterative UX Evaluation phases. Their concerns centered on resource demands, compatibility with agile workflows, and the multidisciplinary skills required, all of which may present barriers for smaller teams. Some respondents also described the framework as elaborate and recommended streamlining.

The authors conclude that the framework is validated for structure and clarity, while acknowledging that its practical feasibility for resource-constrained teams remains an open question. Planned next steps include applying the EDTF in real development projects and creating a lighter-weight toolkit intended for small teams. The supporting literature spans empathic design in serious games, game-based learning foundations, and usability and technology acceptance research, situating the work within ongoing debates about the instructional effectiveness of digital simulation games.
