AACE International CCP Exam Questions

The problem provides key metrics used in Earned Value Management (EVM):

Earned Value (EV): $1,500,000

Actual Cost (AC): $1,000,000

Planned Value (PV): $2,000,000

Key Points:

Schedule Performance Index (SPI):

SPI = EV / PV = $1,500,000 / $2,000,000 = 0.75

An SPI less than 1 indicates the project is behind schedule.

Cost Performance Index (CPI):

CPI = EV / AC = $1,500,000 / $1,000,000 = 1.5

A CPI greater than 1 indicates the project is under budget.

Conclusion: The correct answer is C. Project is behind schedule, but under budget because the SPI indicates a delay in schedule, and the CPI shows that the project is currently spending less than planned.

The statement that the 'means and median are not equal' is incorrect for a standard normal distribution. In a standard normal distribution, the mean, median, and mode are all equal, as the distribution is perfectly symmetrical. The correct characteristics of a standard normal distribution are that approximately 68% of the values fall within one standard deviation of the mean, the total area under the curve is 1, and the curve shape is symmetrical.

Productivity is defined as the measure of the number of units completed divided by the work-hours consumed. It is a key performance indicator in construction and other project-based industries, reflecting how efficiently resources are being used to produce outputs.

Key Points:

Productivity Calculation:

Productivity = Number of units completed / Work-hours consumed.

Higher productivity means more output is being generated per unit of time, indicating efficient use of resources.

Other Terms:

Lined Value: Not a standard term related to productivity.

Credit Work-Hours: A concept related to earned work-hours, not a direct measure of productivity.

Cost Performance Index (CPI): A measure in earned value management indicating the cost efficiency of budgeted resources, calculated as EV/AC.

Conclusion: The correct answer is C. Productivity because it directly refers to the efficiency of labor in terms of output per work-hour.

Productivity loss in projects, particularly in construction, can be measured using various methods. The Earned Value Management (EVM) system includes the Earned Formula to compare the work performed against the work planned.

Key Points:

Earned Formula:

This formula is used in EVM to calculate key performance indicators like the Cost Performance Index (CPI) and Schedule Performance Index (SPI), which help in understanding productivity loss.

By comparing earned value (the work actually performed) against planned value, project managers can assess whether the project is behind or ahead in terms of schedule and budget, indirectly measuring productivity loss.

Other Options:

Central Limit Theorem: This is a statistical concept, not directly used for measuring productivity loss.

Value Engineering: A process that seeks to improve the value of goods or products by using an examination of function, not directly related to measuring productivity loss.

Conclusion: The correct answer is C. Earned formula because it is directly linked to measuring productivity loss in project management through the EVM system.

In a cost reimbursable contract, the contractor is reimbursed for all allowable costs incurred during the project, plus an additional fee (which could be a fixed fee or a percentage of costs). This contract type provides several advantages but also has its limitations.

Key Points:

Advantages of Cost Reimbursable Contracts:

Simpler Proposal Evaluation: The focus is on selecting the best contractor rather than the lowest bid, making the evaluation process simpler.

Flexibility in Dealing with Changes: This contract type allows for adjustments and changes as the project progresses.

Early Start: Work can begin quickly without needing a fully defined scope since costs are reimbursed.

Owner Control:

While cost reimbursable contracts offer flexibility, they do not inherently mean that the owner controls all aspects of the work. The contractor typically manages the execution of the project, while the owner retains control over the budget and major decisions.

Conclusion: The correct answer is D. Owner controls all aspects of the work because, in cost reimbursable contracts, the contractor has significant control over how the work is performed, while the owner mainly controls costs and high-level decisions.
