Start With the Date the Installation Must Be in Hand
The useful milestone is the date the installation needs to be physically available for the team—not simply the public opening time. It needs room for final delivery, site access, unpacking, installation, checks, and a contingency buffer.
Once that date is fixed, the project can be read backwards in the order that affects the actual delivery path. This avoids treating a campaign opening as if it were the only date that matters.
Use the Early Window for Decisions That Change the Project
The earliest stage is where the brief can still absorb site constraints, audience movement, scale, artwork treatment, access, anchoring logic, and operational requirements. These are project decisions, not a generic checklist that can be completed without context.
If any of these inputs are still open, the right next step is a feasibility conversation rather than a promise based on an incomplete direction.
Let the Confirmed Project Schedule Take Priority
A confirmed project schedule reflects the selected structure, approved artwork, production configuration, packed volume, destination, and delivery method. Those conditions cannot be inferred reliably from a broad campaign category.
For that reason, timing published for planning should be treated as context only. The schedule in the project quotation is the decision document for the work.
