Concurrent engineering and integrated manufacturing environments rely on the management of concurrent business processes supported by integrated information systems These business processes and the underlying information systems must be engineered in a systematic way to guarantee compliance with business requirements and overall system consistency and efficiencyIn this paper, the organisation model of the M*-OBJECT methodology is presented as a tool to model business processes and specify design requirements on the information system It covers functional, behavioural, information, and organisation aspects It includes a workflow model, an object flow model, and an interaction model Then it is shown how conceptual design models can be derived from organisation models M*-OBJECT strongly enforces an event-driven process-based approach at all levels as opposed to traditional function-based approaches for analysing and designing computer-supported integrated engineering environments
