_____ estimating occurs at intervals between formal milestone estimates.

_____ estimating occurs at intervals between formal milestone estimates.

• A. Rough
• B. Detailed
• C. Conceptual
• D. Trend

Answer: (D)

Trend estimating focuses on updating cost projections between formal milestone estimates. As the project progresses, you gather current performance data and known factors (actual costs, progress, remaining scope, price changes) and use it to forecast the final cost and cash flow. This provides timely updates to budgets and plans ahead of the next milestone, which is exactly when the estimate is intended to be refreshed. Rough estimates are quick, early approximations made before detailed planning. Conceptual estimates arise in early design when concepts are being explored. Detailed estimates are produced once design is developed and provide a more precise cost at a specific milestone. These are typically aligned with the design stage or milestone, not the ongoing updates between milestones.
