An important distinction amongst enterprises for policymakers is that between those that are growth-oriented and those that are subsistence-based. Policymakers must be aware of the different needs and circumstances of these types of enterprise, of their different capabilities to make use of various ICTs and of the different impacts that ICT interventions may have upon them (chapter IV). There is growing evidence from low-income countries that ICTs - particularly mobile phones - can enable small and micro-enterprises outside the ICT sector to increase productivity, diversify production, develop markets and generally enhance commercial viability (Donner, 2009a, Donner and Escobari, 2009).
