Estimating cost of a production lot of a specific quantity of items planned for a future contract, which is then used for programming and budgeting. It is later used when negotiating the actual contract

95
Q

Type two of the learning curve application is useful when?

A

96
Q

A contract is valid when there is what?

A

1) Has been an offer
2) has been an acceptance of that specific offer
3) has been an intent between two or more parties to create a legal relationship

2) Defense FAR

98
Q

Fixed-Price

100
Q

In which category of a contract does the government bear the majority of the risk?

A

Cost-Reimbursement Contract

Q

Consider an opportunity for a new system that has a $500,000 cost and annual operating cost of $25,000. The proposed system will replace the current capability that has an annual operating cost of $150,000.

A

$500,000 / ($150,000 - $25,000) = 4 years
