DiProMo model: PLS-SEM validation of the link between digital transformation, business model, and productivity

This paper validates the DiProMo model, which seeks to establish relationships among Digital Transformation (DT), the Business Model (BM), and Productivity (P), using a sequential mixed-methods approach that integrates a systematic literature review, expert interviews, and a survey of 318 professionals, whose data were analysed using PLS-SEM in SmartPLS 4. The results show that DT has a significant effect on innovation, which is part of the BM (β = 0.783), which in turn generates a positive effect on P (β = 0.755). Likewise, a direct impact of DT on P is observed (β = 0.734), and a robust partial mediation of DT with P through the BM is also evident. The overall model fit (SRMR = 0.069) and high predictive values (Q² > 0.50) support the validity and utility of the proposed model. The results indicate that P increases when digital investment is aligned with strategic design in BM, providing empirical evidence and practical guidance for organisational management and the formulation of DT policies geared towards competitiveness.
