To measure the productivity gained from computer-based authoring systems, account must be taken of changes in the way the work is organised. An analysis of economists' authoring work, based on diary studies, suggests that much of this is performed at the last minute, just in time to meet deadlines. Benefits gained from word processing appear to be offset by authors' tendency to tinker with documents up to the last minute.
