While the preliminary design largely corresponds to the question "what should be done", detailed design or project is a detailed specification of how to build the system. It is specific and prescribed project/scheme/plan which include technical specifications, detailed time diagram, the development phases and developed handover protocols for each sub-segment/phase/product.

In principle, "anyone" can perform the project only on the basis of performance documentation.

Nobium for its customers makes the performance documentation for systems in the areas of its activity.
