Iterate faster. 
Without risk to your program.

Every change lives on a branch until it's reviewed and approved. PDR and CDR run concurrently, suppliers review live data instead of frozen snapshots, and engineering never stops.

A Flow branch review listing changed items with their downstream impact, next to the branch tree of an electric vehicle program.

Flow brings the Git model to systems engineering. Every change happens on a branch, teams work in parallel, and the baseline changes only when the merge is approved.

Run more work in parallel.

Design, verification, supplier work, and certification activities move concurrently instead of waiting on a shared baseline.

Decouple reviews from development.

Freeze stable snapshots for PDR, CDR, suppliers, and certification while engineering continues forward.

Make change cheap.

Explore alternatives, run trade studies, and test ideas without affecting the live program. Nothing breaks, so engineers experiment more.

Run workstreams in parallel.
The baseline stays stable.

The Flow branch tree with SUV, Electrical Standards, Improve Windows, and New Battery Parts branches off the base branch.

Required reviewers sign off.
Before anything merges.

A reviewers panel with approved, rejected, and pending sign-offs on a branch.

Agents work on branches.
Humans approve their work.

Agent branches opened automatically from a supplier spec, a GitHub pull request, and an updated standard.

And so much more.

Variants and configurations.

Build product families from a shared platform. Create variants such as SUVs, trucks, and coupes, model years like 2026 and 2027, or customer-specific configurations without duplicating engineering work.

Branch-level permissions.

Control visibility at the branch level to securely collaborate with suppliers, partners, and program-specific teams.

Immutable baselines.

Every merge writes a timestamped snapshot of the program. Compare any two baselines in Change History to see exactly what moved between them.

Branch-scoped export.

Export any branch as PDF, DOCX, or CSV for external review, offline editing, or certification workflows.
