NASA SE Handbook Rev.2
Carried as a standard the recipe honours for this class.
A fixed-wing survey UAV, seeded as a worked example: eight requirements, six components, four suppliers and four verifications, wired into a traceability graph, with a real ELANG system_model and an inline Technical Data Package.

Kestrel-1 exists to show the whole chain closed on a small system: eight requirements derived from the need, allocated onto six components, sourced from four suppliers, and each closed by one of four verification activities.
It is the example to read when you want to see needs → requirements → components → suppliers → verification as actual graph edges rather than a diagram of one.
Driven by the UAV recipe over the baseline lifecycle.

Carried as a standard the recipe honours for this class.
Take a survey UAV from need to a released baseline and Technical Data Package, with a verification activity standing behind every requirement.
Derive eight singular requirements from the mission need.
Allocate each requirement onto a component in the architecture.
Source the six components from four qualified suppliers.
Close every requirement with a verification activity of sufficient evidence class.
Author the ELANG system_model and freeze the Technical Data Package.
The first gate: the requirement baseline has to hold before any design proceeds.
Every requirement is singular and verifiable.
A verification method is assigned to each requirement.
The initial hazard list exists.
Every requirement derives from a stated need.
Nothing closes a requirement on JUDGMENT when its verification method demands MEASURED — the evidence class is enforced, not advisory.
