I have a commercial item, FFP contract. We need to descope some work valued around 12% of the contract value. Some of this work is inseparable. Would we do a supplemental agreement removing the work? Or would this be a partial termination for convenience? Also if a decision was made that item 1 is being removed and replaced with item 2. Both items perform a similar function but the design will be different. Does this similar function change any conclusions? Also, this contract is purchasing materials through vendors.
