Four stages, and what you get at the end of each one.
Process
Four stages, with something real handed over at the end of each one.
A week of interviews, an audit of what exists, and a written position you can disagree with. Nothing is drawn yet.
One direction, developed properly, presented with its reasoning. Alternatives exist and get shown as workings, not as a menu.
The system gets made: components, templates, artwork, tokens. Tested against the ugliest real content you have.
Guidelines a non-designer can follow, a decision record for every system-level choice, and two weeks of questions included.
