Learning object reuse is one of the major aspirations of e-learning specifications such as the Shareable Content Object Reference Model (SCORM). Much work has gone into the technical framework for ensuring e-learning content is potentially reusable, however this is not sufficient to ensure that actual reuse can take place. This paper outlines an integrated reusability model which details the major considerations for enabling actual reuse of learning content within organisations. Key factors affecting the viability of learning content reuse are the properties of the learning object itself (structural reuse and contextual reuse); and the organisation's preparedness to undertake learning object reuse (operational reuse and strategic reuse). Reusability at the structural level is determined by how the object has been technically engineered. Contextual reusability is determined by the applicability of a learning object to new learning events and the audience for those events. Operational reusability has dependencies on organisational culture, personnel, procedures and technology. Strategic reusability is a function of organisational strategy that may favour systematic or opportunistic reuse of objects, as well as how the organisation defines the potential market for learning objects. The integrated four-tier model is designed to aid organisations in evaluating the viability of implementing learning object reuse and determining the potential benefits, so that design for reuse efforts can be prioritised and focussed effectively.
