Shift to Model Based Systems Engineering
In the past, engineering projects revolved around ‘document’ and ‘drawing’ centric processes which each contained fragments of information about the whole system. The major downside to this model was that it failed to keep and manage the ‘pieces of information and their connections’. This model also lacked quick access and consistent traceability when project data was examined. It became difficult to assess project completeness, architecture integration, consistency of requirements, change impacts, verification, validation, and end-to-end traceability.
