CCC Cost Estimation & Budgeting — Questions and Answers
Question 1: Which cost estimation method relies on historical data and expert judgment?
- Bottom-up estimation
- Analogous estimation (Correct answer)
- Parametric estimation
- Monte Carlo simulation
Correct answer: Analogous estimation
Analogous estimation uses historical project data and expert experience to estimate costs, making it a quick but less precise method.
Question 2: What is the main purpose of a contingency reserve in budgeting?
- To increase profit margins
- To cover unforeseen risks and uncertainties (Correct answer)
- To reduce material costs
- To eliminate cost variances
Correct answer: To cover unforeseen risks and uncertainties
A contingency reserve is included in the budget to account for unforeseen risks and uncertainties, ensuring financial preparedness for unexpected costs.
Question 3: Which cost estimation technique uses mathematical models and statistical data?
- Analogous estimation
- Parametric estimation (Correct answer)
- Three-point estimation
- Expert judgment
Correct answer: Parametric estimation
Parametric estimation applies statistical relationships between cost variables to predict costs based on unit measurements, making it efficient and data-driven.
Question 4: What is the purpose of Earned Value Management (EVM) in cost control?
- To track project cost efficiency and schedule performance (Correct answer)
- To estimate total project duration
- To replace budgeting entirely
- To eliminate project risk factors
Correct answer: To track project cost efficiency and schedule performance
Earned Value Management (EVM) helps assess project performance by comparing planned, actual, and earned costs to track cost efficiency and schedule performance.
Question 5: Which factor is critical in determining an accurate project budget?
- Team size
- Scope definition (Correct answer)
- Project location
- Marketing strategy
Correct answer: Scope definition
Scope definition is crucial to establishing an accurate budget, as unclear or changing project scopes can lead to cost overruns and budget inaccuracies.
Question 6: What is a key benefit of using a bottom-up estimation approach?
- It is the fastest estimation method
- It provides highly detailed and accurate cost projections (Correct answer)
- It eliminates cost overruns
- It does not require historical data
Correct answer: It provides highly detailed and accurate cost projections
Bottom-up estimation provides highly accurate cost projections by breaking down the project into detailed components and estimating each individually.
