- To augment the project staff
- To provide a solution that may not have a fixed price
- To begin work before a more formal, long-term agreement can be developed
- To acquire experts
The correct answer is 2.
A cost plus contract is preferred when providing a solution that may not have a fixed price. Augmenting the project staff, beginning work before a more formal long-term agreement can be developed, and acquiring experts are all reasons for using a time and materials contract.
