Request for Proposal, Contract, External Unit Specification, Contract Addendum, External Hardware Module Specification, External Software Module Specification |
When a subsystem is awarded, the current state of the »External Unit Specification, »External Hardware Module Specification or »External Software Module Specification becomes part of the »Request for Proposal.
Depending on the award procedure, it may be possible to renegotiate changes in these specifications that emerged after the mailing of the »Request for Proposal. Between public purchasers and suppliers, contract negotiations are possible only with limitations. If this happens before the »Offers are submitted, public purchasers may have to grant an extension of the closing date and inform all possible »Sub-Suppliers.
The state of the »External Unit Specification , »External Hardware Module Specification or »External Software Module Specification that is valid at the time of the contract is part of the »Contract. After the conclusion of the contract, the contract is no longer updated, i. e. possible future changes of these specifications no longer have an impact on the contract and are settled by way of contract addenda (see »Contract Addendum).
