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:
““The tree of knowledge is not the tree of life!” And yet can we cast out of our spirits all the good or evil poured into them by so many learned generations? Ignorance cannot be learned.”
—Gérard De Nerval (1808–1855)
