How to Cut CBI Development Costs in Half: Commentary on Foshay and Preese
Joseph M. Scandura
Cost estimates presented in Foshay and Preese are based on a long commercially successful history and, hence, are particularly valuable in comparing alternative authoring methods. AuthorIT provides an extreme case because it automates many authoring processes: a) The need to program pedagogy (delivery modes) is completely eliminated, irrespective of the structure of the content to be delivered. b) Dialog-box-based configurability enables AuthorIT to support multiple pedagogies — ranging from selfdirected to highly adaptive — without programming and at no additional cost. Both are of critical importance in maintaining quality control and reducing costs. While further work is planned, AuthorIT already supports most kinds of learning and tutorial development. Prototype development to date has yielded time and cost savings of 50% or more.
