The survey also revealed that firms adopting one information technology are likely to adopt others and that they follow a sequence in adopting information technologies. We identified the IT adoption sequence by estimating, through the Bayes theorem, the likelihood of a firm's adopting a specific technology after having adopted a set of more basic technologies. We propose a classification for information technologies according to their place in the adoption sequence: infrastructure technologies, intermediate technologies, and advanced technologieengFinancial InstitutionsAdoption Information Technologies (IT)ManagementCompetitive Strategiesjournal article
