The Level 1 diagrams represent the typical work processes based on organization roles (disciplines), with a focus on the deliverables produced by that discipline and how that discipline interacts with other disciplines. At this level, no specific tools are described.
The Level 2 diagrams represent the sequence of major tasks performed using Hexagon solutions, and other tools, to produce each deliverable for that discipline. While there are multiple ways to produce a deliverable, the work processes described in this document represent typical paths using Hexagon solutions (out-of-the box, or with minimum configuration) with SDB recommendation and best practices and do not include system customizations that could further enhance the work processes.
