- Analysis of usability in digital design by integrating Kano, WebQual and QFD models: The case of the interior design Website+Publication . Raposo, Daniel; Veríssimo, Fátima; Paiva, Teresa; Neves, João Vasco; Felgueira, TeresaThis study proposes a structured, replicable, multimethod framework for evaluating the usability of institutional information systems serving heterogeneous user groups. It adresses the limited integration of expectation–satisfaction analysis, perception-based quality assessment, and technical prioritisation by combining the Kano Model, WebQual 4.0, Quality Function Deployment (QFD), and heuristic evaluation within a unified workflow. The framework was applied to the Interior+ platform through a user survey (n = 40) and an expert heuristic inspection (n = 4). Results indicate that usability, responsiveness, and information clarity serve as basic (must-be) attributes, leading to high potential for dissatisfaction when performance is inadequate. In contrast, multimedia content and personalisation emerged as attractive attributes that enhance satisfaction without generating substantial dissatisfaction when absent. The integration of Kano, WebQual, and QFD enabled the systematic prioritisation of technical improvements, while comparison with expert evaluations revealed an 80% convergence between user-derived priorities and heuristic recommendations. The findings also highlight meaningful divergences between users and experts, particularly regarding information clarity, reinforcing the value of triangulated evaluation approaches. The study contributes a practical, operationalised protocol that integrates user perceptions, expert assessments, and decision-support tools to inform evidence-based usability improvements and the development of more inclusive, effective, and user-centred institutional digital platforms.
- Driving agricultural innovation: The role of collaborative networks in the INTERIOR+ Project under the Triple Helix FrameworkPublication . Paiva, Teresa; Raposo, Daniel; Andrade, L.P.; Delgado, F.M.G.; Verissímo, Fátima; Coutinho, Paula; Rodrigues, Ana; Brito, Nuno; Raposo, DanielFostering and developing agricultural innovation is critical to addressing global challenges such as food security, climate change, and sustainable develop-ment. This study adopted a descriptive case study design combining document anal-ysis and semi-structured interviews with representatives from academia, industry, and government involved in the INTERIOR+ project. It explores the potential of cross-sectoral collaboration within a triple helix context to accelerate the adoption of innovative practices and technologies in the agriculture sector. The analysis iden-tified key collaborative mechanisms, knowledge sharing, digital connectivity, and stakeholder intermediation, that enhance innovation capacity in low-density agricul-tural territories. Findings show that integrating Collaborative Innovation Networks (COINs) within a Triple Helix framework fosters resilience, accelerates technology adoption, and supports sustainable rural development. Moreover, the study provides practical insights on how to establish and sustain these networks, highlighting the critical role of stakeholders in leveraging the potential of COINs and cross-sectoral collaboration to propel agricultural innovation and development, and, therefore, in designing an intersectoral collaboration strategy.
- Influencia del diseño de packaging en la percepción de calidad del producto. Un estudio sobre alimentos típicos de la zona centro de PortugalPublication . Raposo, Daniel; Carballo, Fernando Suárez; Neves, João Vasco; Veríssimo, Fátima; Paiva, Teresa; Felgueira, TeresaSegún la literatura científica, el diseño del packaging constituye un factor esencial en la construcción del valor simbólico del producto y, por tanto, condiciona la intención de compra de los consumidores. Partiendo de esta afirmación, el estudio analiza la influencia del envase en la percepción de calidad de alimentos típicos del centro de Portugal (Beira Baixa, Beira Alta y Alto Minho) como el aceite, la miel, el vino, los ahumados y la fruta. El objetivo principal es determinar si la calidad y la innovación del diseño de packaging influyen directamente en la percepción de calidad del producto y analizar la repercusión de varios atributos (forma, material, rótulo, diseño gráfico y otros componentes) en esta valoración. Para ello, la metodología de la investigación combina un panel de siete expertos en diseño gráfico (para una evaluación del diseño de packaging) y una encuesta mixta (cuantitativa y cualitativa) aplicada a consumidores (n = 75). Los resultados revelan una relación significativa entre la calidad del diseño y la calidad atribuida al producto, así como la especial repercusión del diseño gráfico de la etiqueta en estas valoraciones.
