THE REQUIREMENTS LIFECYCLE

From a drafted requirement to a traceable test

(01)

Draft requirements

Writes requirements in the discipline's form — single behavior, measurable bound, declared condition.

(02)

Quality checks

Flags ambiguity, untestable phrasing, compound clauses, and missing tolerances — before review.

(03)

Bidirectional trace

Parent ↔ child ↔ test linkage maintained and audited; orphans and childless parents surfaced.

(04)

Convert to test cases

Derives test cases with inputs, expected results, and pass criteria from each requirement.

(05)

Coverage & change impact

Reports trace coverage and shows exactly which artifacts a requirement change touches.

A WORKED ARTIFACT

Requirements verified before they cost you

TELOS reports the drafted statement, the quality findings, the bidirectional trace, and the derived test case — a record an assessor can follow from parent requirement to executed check.
