Enterprise competency refers to knowledge that describes the skills and abilities possessed by a particular enterprise. This paper proposes a new framework for intra-enterprise competency modelling. First, formal definitions of enterprise competency and related aspects (i.e. resource, activity, and knowledge) are presented. Second, conceptual subcategories (i.e. capability, cross-functional co-ordination, and cross-functional integration) are discussed for the purposes of capability and competency modelling. The framework is illustrated by developing a competency knowledge base for a bicycle plant with two sectors. The competency knowledge base provides information important to decision-making, and can act as an indicator for an enterprise's willingness to engage in robust collaboration.
