Which cost estimating approach requires detailed and extensive knowledge of the product or process?

• A. Analytical Method
• B. Engineering Approach
• C. Parametric Approach
• D. Delphi Method

Answer: (B)

Engineering approach requires detailed and extensive knowledge of the product or process. This method builds the estimate from the ground up using actual design data, such as the bill of materials, process steps, tolerances, manufacturing methods, tooling, setup times, and labor and material specifics. Because it ties costs directly to how the product is engineered and manufactured, you need in-depth understanding of every component and operation to accurately capture each cost driver. This depth is essential for complex or custom items where small design differences can significantly affect cost, making a bottom-up, data-rich estimate the most reliable. In contrast, other approaches rely more on generalized data or judgments. The analytical method uses mathematical relationships and formulas that may not require exhaustive product details. The parametric approach estimates costs using cost drivers and historical data, which providesSpeed more high-level projections than a full engineering bill of materials would. The Delphi method depends on iterative expert opinions to reach consensus, rather than detailed design data, so it doesn’t inherently demand deep product knowledge.
