The Root Problem: Informal Kickoffs Create Scope Chaos

Step 2: Collect All Assets in One Sitting

Never ask for assets in an open-ended email. Build a 25-point intake checklist that requests vector logos (.SVG/.AI), typography, hex codes, CMS logins, analytics access, and competitor links in a single form.
