SSPLAXBiologics Tech Transfer
When every team is busy, which gate is really on the launch critical path?
Engineering evidence → PPQ → validation filing
Launch window output
~3.2 lot-equivalents by Month 8
Minimum transfer spend
~$3.1M to hit the window
Decision path
Critical path
Situation
The receiving site must complete transfer, engineering, PPQ, validation, and filing inside an eight-month launch window.
Model logic
Tracks evidence as it moves through each transfer gate and waits for the next gate to open.
Bank donor and analytical evidence before the PPQ window opens.
Earlier PPQ slots do not help unless engineering evidence and filing capacity are ready.
The controlling sequence is engineering evidence → PPQ → validation and filing.
Keep engineering evidence ahead of PPQ, then protect validation and filing capacity as PPQ lots finish.
