Meaning
Interim written authorizations permit a supplier to begin a restricted portion of work before a final contract takes effect. The limited notice to proceed enables the early procurement of long-lead items or the start of preliminary engineering design. It limits the buyer’s liability to a specified budget and scope of work.
This document expires once the full notice to proceed is issued or the specified funding is exhausted.
Operational Scope
Project managers use this interim authorization to secure critical supply chain slots while final contract terms undergo legal review. Initiating a limited notice to proceed helps prevent schedule slippage on high-priority manufacturing lines. It allows the supplier to demonstrate pilot results before the buyer commits to a full production rate.
Transition Phase
Early work conducted under this limited mandate focuses on activities that directly reduce subsequent schedule risks. Ordering specialized tooling and completing raw material audits are typical tasks completed during this transition phase.
Financial Ceiling
The authorization includes a strict monetary limit that the supplier cannot exceed without written permission. (If the supplier spends beyond this cap before full contract execution, they bear the financial risk.) This ceiling protects the buying organization from major financial exposure if the project is cancelled before full production begins. It ensures that any early expenditures are controlled, audited, and aligned with the preliminary development budget.
