Recently I'm getting more into IT management, thanks to the mentoring of the professors at MOSI (E. Torfs and E. Vandijck). During reading in the book "Corporate Information Strategy and Management" I came across the concept and examples of B2B, what stands for "Business to Business". The concept C2C (customers), like ebay was of course known to me. The B2B example was Covisint. Using the web for B2C may be the most strait forward e-commerce example.
