The aim of the present paper is to discuss the relevance of an index capable of measuring the digital divide among small and medium enterprises (SMEs) and discuss its importance in the context of public policies. The contention is that the digital divide mainly affects SMEs, and that this phenomenon is related to the low productivity and high mortality rates of these organizations. The methodology for creating the index is replicated here in order to discuss the quality criteria necessary for the index, within the scope of its utility for public managers.
