Requirements for a Metamodel to Facilitate Knowledge Sharing between Project Stakeholders

The successful realization of the goal of Model-Based Systems Engineering (MBSE) practice, to contain all project information in models, is predicated on the ability of the system model to represent the information needs of a broad range of stakeholders such as the owners, acquirers, suppliers, maintainers, and users. The paper opens by discussing the interface between the acquirer and supplier within the pre-contract competitive Australian defence context. From this and earlier work, the need for the model of the system of interest to be built upon a comprehensive knowledge representation that can support the creation and integration of multiple stakeholder specific models is derived. Elicitation of further requirements from both stakeholder workshops and from functional analysis follows. Refereed/Peer-reviewed
