A cost consultant identifies a systematic overestimation of labor productivity in multiple project estimates. This type of recurring error is BEST characterized as:
Answer: Systematic bias
Recurring errors in the same direction across multiple estimates indicate systematic bias, which must be corrected through process improvement or calibration.
Which AACE Recommended Practice provides guidance on the required content and format for a basis of estimate document?
Answer: RP 34R-05
AACE RP 34R-05 specifically addresses the required content and structure for a basis of estimate document in cost engineering.
An owner requires that all cost estimates submitted by contractors be independently validated. This requirement is an example of which quality management function?
Answer: Quality assurance
Requiring independent validation of estimates is a quality assurance function, as it ensures systematic processes are in place to maintain estimate reliability.
Which statistical tool is MOST useful for identifying whether cost estimate variations are within acceptable control limits over time?
Answer: Control chart
Control charts track process performance over time and display upper and lower control limits to identify whether variations are within acceptable ranges.
A contractor submits a change order supported by cost data from a similar but much larger project. What quality concern does this raise?
Answer: The unit costs may not be scalable and may not reflect the actual scope
Cost data from projects of significantly different scale may not translate accurately due to economies or diseconomies of scale, making the comparison unreliable.
In the context of earned value management, which metric directly indicates whether the project's cost performance is meeting quality thresholds?
Answer: Cost Performance Index (CPI)
The Cost Performance Index (CPI) measures cost efficiency and directly indicates whether the project is performing within its approved cost quality thresholds.
Which of the following BEST describes the purpose of calibrating historical cost data before using it in a new estimate?
Answer: To adjust historical costs for location, time, and scope differences to make them comparable
Calibration adjusts historical data for factors like location, time period, and scope differences so that it is a valid basis for new estimates.
