The short version
A campaign is a dated event. Work that arrives after the date has a value close to zero regardless of quality.
What is really going on
Media is bought in advance. A late master does not delay the launch — it misses it.
Every day of overrun consumes someone else's schedule downstream: edit, sound, localisation, legal.
Quality is a range; deadlines are binary. Optimising the binary constraint first is simply better maths.
How to handle it
Scope to eighty percent of available time and treat the remainder as protected contingency.
Freeze the look earlier than feels comfortable — polish is the compressible phase, structure is not.
If the deadline is genuinely impossible, say so on day one and propose a reduced deliverable list.
The takeaway
Deliver on time at ninety percent, then offer a polish pass. That sequence keeps both the date and the quality.
