Which of the following is a project constraint?

Question

Options

• ATwenty-five percent staff turnover is expected.
• BThe technology to be used is cutting-edge.
• CProject leadership may change due to volatile political environment.
• DThe product is needed in 250 days.

• A
  9% (4)
• B
  17% (8)
• C
  2% (1)
• D
  72% (33)

Explanation

Option D is correct because a project constraint is a fixed limitation that bounds the project's execution - a hard deadline of 250 days directly restricts when the project must be completed, making it a classic time constraint (one of the triple constraints: scope, time, cost).

• A is wrong because staff turnover is a risk - an uncertain event that may occur and could impact the project, not a firm boundary imposed on it.
• B is wrong because cutting-edge technology is an assumption or potentially a risk/complexity factor - it describes the nature of the work, not a binding limitation.
• C is wrong because potential leadership change is also a risk - it's conditional ("may change") rather than a defined, fixed constraint.

Memory tip: Think of constraints as things someone outside the project team has already decided for you - budget caps, fixed deadlines, regulatory requirements. If it says "may" or "expected," it's a risk, not a constraint. Constraints are certain; risks are uncertain.
