Small and medium-sized enterprises (SMEs) are essential to employment, resilience and competitiveness in North and Central Asia. Yet, many SMEs continue to face barriers in accessing and using digital public services (DPS). Fragmented delivery, uneven broadband, complex procedures, limited interoperability and digital skills gaps reduce SME participation in the formal economy and weaken the impact of national digital transformation programmes. This working paper presents the Digital Maturity Framework (DMF) and the concept of an interstate Digital Business Card (DBC). They are developed by the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) under the Asia-Pacific Information Superhighway (APIS) initiative. Grounded in the ESCAP Digital Transformation Index (DTI) and its three-stage approach (Foundation, Adoption and Acceleration), the DMF provides a structured methodology to assess and strengthen DPS for SMEs. It is implemented through two complementary surveys capturing both the supply and demand sides of the digital ecosystem.
