  • Business Productivity and the Adoption of Lean and Industry 4.0 Tools: A Regional Study
    Publication . Guimarães, André; Rosivalda Pereira; Pereira, Marisa; Pereira,Maria Teresa
    This study investigates the relationship between the adoption levels of Lean and Industry 4.0 (I4.0) tools and business productivity among 140 industrial companies in the Central Region of Portugal. Lean and I4.0 adoption indices were constructed and categorized into tertiles. Productivity data were retrieved from the SABI database. Statistical analysis using non-parametric methods revealed a marginally significant association between Lean tool adoption and productivity (Kruskal-Wallis H(2) = 5.30, p = 0.071), indicating a positive trend. In contrast, a statistically significant relationship was found for Industry 4.0 adoption (H(2) = 8.39, p = 0.015, Dunn’s p = 0.039), with companies with low adoption levels underperforming those with medium and high levels. No significant productivity differences were observed by firm size (p = 0.154). These findings highlight the relevance of Lean and I4.0 tools as productivity drivers, regardless of company size, and underscore the importance of promoting structured digital and operational transformation strategies in low digital maturity regions.

  • The Paradox Between Concept Knowledge and Digital Maturity Level for Industry 4.0: The Portuguese Case
    Publication . Guimarães, André; Rosivalda Pereira; Maria Teresa Pereira; Afonso Carvalho; Reis, Pedro; Antonio J. Marques Marques Cardoso
    This study examines whether companies’ knowledge of the Industry 4.0 concept, geographic location, and size influence the digital maturity of Portuguese industrial firms. Data were collected through a self-assessment questionnaire based on the IMPULS model and analyzed using ordinal logistic regression and chi-square tests to test three hypotheses. The results show that none of these factors significantly affects digital maturity, suggesting that isolated variables do not fully explain digital progress and that broader contextual elements, such as support programs and internal digital strategies, may play a more decisive role. The study meets its objectives and contributes to understanding digital readiness in the Portuguese industrial context. Future research should incorporate additional variables, employ longitudinal or sector-specific approaches, and utilize qualitative methods to enhance the analysis further.
