Robert Annett has been a developer since 1995 and has worked in industries from energy management to investment banking. Much of his work has involved upgrading and migrating legacy systems, with the occasional green-field project (involving integration to legacy systems, of course). He has worked in the IT industry long enough to realize that all successful systems become legacy eventually.
