The invention concerns a tool and method for capturing information gathered during an analysis project. Such information may comprise engineering design or other decision making rationale. The invention comprises a storage means for storing the analysis information generated or acquired during progress of an analysis project, wherein the analysis information is in the form of a plurality of graphical representations. Each graphical representation denotes a plurality of entities under analysis and the plurality of graphical representations comprises at least one representation of a first kind and at least one representation of a second kind. Input means is provided to allow a user to generate each graphical representation using a first or second predetermined structure according to its kind, said graphical representations being arranged for storage as a plurality of graphical representation files in the storage means. Presentation means allow for subsequent retrieval and presenting of the analysis information. A bi-directional link is created between different graphical representations denoting a common entity under analysis so as to allow navigation between the linked graphical representations by traversing the bi-directional link in either direction.
