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.
