The critical path for a project is best described as the

Question

Options

• Asequence of steps with the highest costs
• Btasks in the project that have the highest risk of failure
• Csum of the tasks with the shortest time requirements
• Dlongest path from the start to the completion of the project

• A
  4% (1)
• B
  4% (1)
• C
  7% (2)
• D
  85% (23)

Explanation

Critical path refers to the longest sequence of dependent tasks from project start to finish - option D - because it determines the minimum total time needed to complete the project; any delay on this path directly delays the entire project.

Option A is wrong because cost has no bearing on the critical path - expensive tasks can have plenty of float and never appear on it. Option B is wrong because risk level is irrelevant; low-risk, routine tasks can be on the critical path. Option C is wrong because it's the longest path, not the shortest - tasks with the shortest durations often have slack and aren't critical at all.

Memory tip: Think of the critical path as the bottleneck highway - it's the longest route you must travel, and a traffic jam anywhere on it holds up the whole trip.
