Abstract
In recent years, various companies have entered into e-business market to obtain huge market profits and to achieve competitive advantage. Most of them, however, have neither earned expected cash flow nor achieved competitive advantage by developing and using Electronic Commerce sites. Also they have not acknowledged success factors of e-business clearly. This paper clarified what are success factors of e-business to provide reasonable assurance for e-business development in which enterprises could distinguish sales of "real products". As a result, it aims to construct supporting framework for effective project selection of e-business development by making clear supportable success factors by means of information technology^<[1]>
