Specification Tree
The spacecraft system specification defines also the subsystems of the spacecraft e.g.:
- Structure
- Data management subsystem incl. software
- Electrical Power
- Mechanical
- etc.
For each subsystem a subsystem specification is prepared by the Prime Contractor with the same specification structure shown above including references to the parent paragraph in the system specification. In the same way the subsystem contractor prepares an assembly or unit specification. All these specifications are listed in a so-called specification tree showing all specifications and their linkage as well as the issue / date of each specification.

Famous quotes containing the word tree:
“There was not a tree as far as we could see, and that was many miles each way, the general level of the upland being about the same everywhere. Even from the Atlantic side we overlooked the Bay, and saw to Manomet Point in Plymouth, and better from that side because it was the highest.”
—Henry David Thoreau (1817–1862)
