As PRINCE2® is based on a customer/supplier context from the customer perspective, it is unlikely that the processes need to be tailored from the customer perspective.
From a supplier’s perspective, the key change to the processes will be to the Starting up a Project and Initiating a Project processes.
The Starting up a Project process will take place pre-contract and is typically in response to the customer’s request for a proposal.
Some of the Initiating a Project process will be pre-contract as the supplier will need to formulate the strategies, plans and controls in order to assess the viability and desirability of the sale, and the associated costs and prices of the solution being proposed.
The Initiating a Project process is not completed, however, until contract negotiation has concluded and the customer’s Project Board authorizes the project.
Contract negotiation should be managed under change control.
An additional requirement is to align the supplier’s business approval processes with the Starting up a Project process (qualifying the opportunity) and the Initiating the Project process (approving the proposal).
A tactical approach is to prepare any project documentation to ‘final draft’ status during pre-contract activities, for it then to be approved as part of the contract award.
