Developing a Sustainable Digital Transformation Roadmap for SMEs: Integrating Digital Maturity and Strategic Alignment

Digital transformation (DT) is crucial for SMEs to streamline operational efficiency, foster innovation, and meet upcoming challenges. Integrating sustainability into this process not only enhances a company’s reputation but also attracts customers and investors who value environmental responsibility. Despite this opportunity, many SMEs operate without clear plans and strategies. The literature review identified a lack of roadmaps that integrate sustainability into the digital transformation process for SMEs. Thus, this paper aims to propose a sustainable digital transformation roadmap for SMEs that evaluates their digital maturity and facilitates gradual implementation in alignment with their strategic objectives. A systematic literature review using the Methodi Ordinatio defined six key dimensions of digital transformation. Consequently, the SDT-SMEs Roadmap was developed, drawing on ISO/IEC 33000 standards to offer well-defined processes for enhancing digital competencies. The roadmap features three organizational planning levels—strategic, tactical, and operational—and includes a maturity model that evaluates 75 processes across six dimensions: Digital Technologies, Customer Focus, Organizational Culture, Organizational Governance, People, and Sustainability. Validation through a case study confirmed the roadmap’s effectiveness in addressing real-world challenges and guiding SMEs through the digitization process. The SDT-SMEs Roadmap provides a comprehensive and integrated approach, ensuring continuous adaptation and improvement in sustainable digital transformation efforts. This roadmap addresses a significant gap in the literature and presents a practical, strategic, and adaptable pathway for SMEs embarking on their digital transformation journeys.
