If a lump of software is allowed into the "it works, do no touch it" then that is the beginning of the end for that product and that company. The accountants probably haven't realised it at the time they make that decision, but they have just signed the death warrant on that part of their organisation. An organisation that keeps all of it's software in development at all times may appear to spend more on development, but they are keeping the organisation codebase in a fit state for evolution. As the market changes, the organisation can change without massive revolution. The difference here is between an organisation that treats software as a cost versus software as an asset. As long as you do not measure the asset by lines of code, obviously. The rather interesting anecdote of the moment is FORTRAN (and Fortran). Various code bases written in the 1960s must still be compilable by current Fortran compilers because no-one is allowed to alter the source code of the 1960s codes. This makes Fortran one of the weirdest languages, and their compiler writers some of the best. Note though that all the organisation who followed the "the source code is fine now" are having real troubles hiring FORTRAN and Fortran developers, c.f. UK government and NASA. I believe some organisations are having to hire at £2000 per day for these people. So for the accountants: you need to look further than the next three months when it comes to your assets and bottom line over the lifetime of the organisation. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
