What is the least prefered contract type by the government?

The least preferred contract type by the government is typically the cost-plus contract. This type of contract can lead to inefficiencies and higher costs, as it reimburses the contractor for all allowable expenses plus an additional amount for profit, which may reduce the incentive to control costs. Governments often favor fixed-price contracts, which provide more predictable budgeting and encourage contractors to complete projects within a specified budget.
