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 certification programs lose time
Every gap below is a familiar audit finding — and every one is a symptom of evidence living in disconnected spreadsheets instead of one traceable thread.
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.
Six stages. One continuous thread.
Each stage hands its evidence directly to the next — nothing gets re-entered, and nothing goes stale.
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 →Built for avionics. Proven wherever software is regulated.
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.
