Delivery architecture

What the engagement protects.

The medium changes. These working guarantees do not.

01 / Owned

Owned

Source files, working assets and handover notes leave with you.

02 / Verified

Verified

The agreed output is checked in its real delivery context.

03 / Direct

Direct

No subcontractor chain between the brief and the build.

04 / Scoped

Scoped

The outcome, exclusions and price are visible before production.

Build sequence

Four visible moves.

Signal

Define the audience, input, output, deadline and real constraint.

Scope

Agree the smallest useful deliverable, exclusions and one flat number.

Produce

Build, show working progress and revise against the agreed outcome.

Transfer

Verify the final result, deliver the files and document the handover.
