Traditionally, support for authoringeducational software focuses on the authoringprocess: the nature and sequence of theactivities that must be performed to deliverthe required product. As a consequence, themethods that are used tend to have a stronglinear flavor, which resembles the classicalwaterfall approach. Development strategies ascurrently used in software engineering shiftthe attention from activities to products(see De Hoog et al., 1994). A generalimplementation of this approach can be found inthe CommonKADS methodology (see Schreiber etal., 2000). The present article describes howthis new development approach has influencedthe design of an authoring system formulti-media simulation based educationalsoftware, the Simquest authoring system.
