Which contractual arrangement is the least risky option for Mahmoud, the contractor?

• A. Fixed price level of effort
• B. Fixed price with a defined scope
• C. Time and materials
• D. Cost-plus with a target

Answer: (A)

The key idea here is how risk is allocated between buyer and contractor in different contract types. A fixed price for a defined level of effort gives Mahmoud a predictable, capped pay for a specific amount of work hours. He can plan staffing and scheduling to meet that level of effort, knowing exactly what revenue he’ll receive if he delivers as planned. There’s less ambiguity about what’s expected, and no ongoing dispute over changing costs or deliverables. If the defined effort is realistic and he can execute efficiently, profits are straightforward and protected by the fixed price.

In contrast, time and materials or cost-plus with a target expose the contractor to cost variations and potential overruns (since payment tracks actual costs or shared savings), while fixed-price contracts with defined scope can become risky if the scope isn’t well controlled or if changes occur. Therefore, the fixed price for a defined level of effort minimizes Mahmoud’s financial uncertainty and is the most predictable option among the choices.
