One requirement.
One unbroken thread of evidence.
PES keeps requirements, traceability, reviews, and validation evidence connected end to end — so certification programs stop rebuilding proof by hand and start shipping it.
Where programs lose time — and how PES closes the gap
Every finding on the left is a familiar audit symptom of evidence living in disconnected spreadsheets. On the right, the PES capability that removes it — one continuous thread instead of many.
The same checks, repeated by hand, every cycle
Each requirement is manually checked against its upstream requirements, checklists, and standards — review after review. It's slow, and the result depends on who happens to be reviewing.
Impact paths are guessed, not shown
When a requirement changes, tracing its effect across system, software, design, and test layers becomes archaeology instead of a lookup.
Change authorization has no single record
Requirement edits and their approvals live in email threads and change logs that don't talk to each other — audit trails get rebuilt after the fact.
Evidence is assembled, not maintained
Test evidence and audit readiness get compiled the week before a milestone, instead of accumulating continuously as work happens.
Current tools manage requirements — they don't engineer them
Mainstream tools store, track, and manage requirements, but offer no real requirement engineering — and no AI-driven assistance for drafting, decomposition, quality review, or improvement built into the workflow.
Requirement Engineering
Decompose, import, and review engineering requirements against controlled baselines — with history that survives every revision.
Explore capability →Traceability & Impact Analysis
Track upstream and downstream relationships across system, software, design, and test artifacts in one view.
Explore capability →PR/CR & Review Management
Authorize edits, review downstream impact, and keep every change decision auditable from request to resolution.
Explore capability →AI-Assisted Self-Review
Configurable quality profiles flag ambiguity and gaps before a requirement ever reaches a formal review cycle.
Explore capability →Test Case Generation
Generate validation-oriented test cases directly from structured requirements and their trace context.
Explore capability →Baseline & Audit Readiness
Maintain review evidence, version history, and lifecycle records so audit readiness is a standing state, not a scramble.
Explore capability →We've sat on the other side of the audit table.
PES is built by engineers with hands-on DO-178C and ARP4754A/ARP4761 background — not a generic project tracker retrofitted for compliance.
