The arrival of Information and Communication Technology may play a role in restoring competitiveness, since these technologies are also a factor in relaxing the constraints specific to SMEs. ICT makes a number of services possible in a large range of processes and transactions within and between companies. Internally, ICT applications can improve knowledge and information management practices; they can also allow more rapid and more reliable transactions between businesses (B2B) and between businesses and consumers (B2C). They are equally quite effective in improving external business communications and service quality for both new and existing clients. They also appear to be a source of competitive advantage for SMEs under certain conditions. Few studies have focused on the ways that SMEs can use ICT to improve and defend their competitive positions. This book provides a synthesis of the advantages of ICT for SMEs. Seven chapter illustrate the technologies used in such companies. Each of these chapters provides a theoretical and/or practical view of the way that SMEs can use ICT. This book is an indispensable reference for both academics and for practitioners.
