Cost Estimation & Budget Control Flashcards

What is the primary purpose of cost estimation in engineering projects?

Answer: Forecast total expenses

The primary purpose of cost estimation in engineering projects is to forecast the total financial resources required to complete the project successfully. This involves predicting all anticipated expenses, including labor, materials, equipment, and overheads, to establish a realistic budget and provide a basis for financial planning and decision-making.

Which cost estimation method uses historical data from similar projects?

Answer: Analogous estimating

Analogous estimating, also known as top-down estimating, is a method that uses historical data from previous, similar projects to estimate the cost or duration of a current project. This technique is often used early in the project lifecycle when detailed information is limited, providing a quick, high-level estimate based on expert judgment and past experience.

What is the purpose of budget control?

Answer: Track spending within limits

Budget control is essential in project management to monitor and manage project expenditures, ensuring they remain within the approved financial limits. It involves regularly comparing actual costs against the planned budget, identifying variances, and taking corrective actions to keep the project on track financially and prevent cost overruns.

Which document outlines the approved budget for a project?

Answer: Cost baseline

The cost baseline is the approved version of the project budget, typically presented in a time-phased manner, against which project cost performance is measured. It represents the sum of the approved budgets for all scheduled work packages and control accounts, serving as a critical reference point for tracking and controlling project costs.

What is contingency reserve used for?

Answer: For identified risks

Contingency reserve is a specific amount of money or time set aside in a project budget to cover known-unknown risks, meaning risks that have been identified but whose impact or occurrence is uncertain. It is used to manage the expected costs associated with these identified risks, ensuring the project can absorb their impact without derailing the budget.

Which cost control technique involves comparing planned and actual costs?

Answer: Earned Value Management (EVM)

Earned Value Management (EVM) is a powerful project management methodology that integrates scope, schedule, and cost performance into a single system. It systematically compares the planned value of work, the actual cost incurred, and the earned value of work performed, providing a comprehensive view of project performance and enabling proactive cost control.

What is cost variance?

Answer: Difference between budgeted & actual costs

Cost variance (CV) is a key metric in project cost control, representing the difference between the earned value (EV) of work performed and the actual cost (AC) incurred. A positive CV indicates that the project is under budget for the work completed, while a negative CV signifies that it is over budget, highlighting areas needing attention.

Why is forecasting important in budget control?

Answer: Predicts future costs

Forecasting is crucial in budget control because it involves estimating future project costs based on current performance and trends. By regularly predicting the Estimated Cost at Completion (EAC) or Estimate to Complete (ETC), project managers can anticipate potential budget overruns or underruns, allowing for timely adjustments and informed decision-making to keep the project financially viable.

What is a key benefit of effective budget control?

Answer: Completes project within budget

A key benefit of effective budget control is the increased likelihood of completing the project within its approved financial limits. By continuously monitoring expenditures, identifying variances, and implementing corrective actions, project managers can prevent cost overruns, ensuring financial discipline and maximizing the project's return on investment.
