Question

Quizplus · Accepted Answer

Top-down estimates are usually made during the initiation phase of a project, where limited information is available. Hence, the accuracy of such estimates is generally lower than bottom-up estimates. However, they provide a rough indication of the project's scale and scope. The range of accuracy for top-down estimates is usually between minus 20% to plus 60%. Hence, option C is the best choice. Option A and option B have too wide of a range, whereas option D and option E have too narrow of a range.
