Cost of conversion for proprietary vertical and horizontal applications. The R&D cost of in house applications is amortised over 1 user. The R&D cost of commercially available applications is amortized over the end-user Typically for In house applications, there is only here-and-now expense related with rewriting an existing application to a new HW/SW platform. So existing applications don't get rewritten and new applications are done in new technology. In-house applications in the 'new technology' are the Legacy applications of tomorrow. > <un-snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
