g) After finishing of all procedures, two possible outcomes exist. In the first case, problems have occurred after the previous checks. This forces the hardware design department to revise the problematic component(s). If a peripheral needs to be replaced, the whole process starts over from adding a new one. If the revision has been successful or the second case applies (when the previous checks are done without any problems), the hardware department finishes the check-up. As a result, a checked schematic and a 3D model of the board are available and also the library is updated. The materials management department can now order the components. Once they are received, the hardware design department does the final placement. As the final outcomes, both the placement and the preliminary layout are done.
