Build-to-spec assembly

Build-to-spec assembly means the build follows a released work instruction and drawing package, and a change to it goes through document control before the floor sees it — a revision, not a verbal correction at the bench. First-article inspection is the gate: one unit is built and verified to the drawing, and only after it signs off does the balance of the lot run, each unit stamped with a serial that ties back to the traveler it was built from.
For small-lot production runs where a full contract-manufacturing relationship isn't justified, we scale the same process down without cutting the quality steps: work instructions, first-article sign-off and test records still travel with every unit.
- Controlled work instructions and released bill of materials per build
- First-article inspection before the balance of the lot runs
- Serialized units traceable to their build traveler
- Same process from single-digit builds to multi-hundred-unit lots
