Which technique is used to identify the root cause of a quality defect by repeatedly asking 'why' until the fundamental cause is discovered?
Answer: 5 Whys Analysis
The 5 Whys technique drills down through symptom layers by asking 'why' iteratively, typically five times, to reach the root cause of a problem.
A project manager identifies that a subcontractor's scaffolding erection poses an imminent danger. What authority does the Construction Manager have?
Answer: The CM can stop work in the affected area to protect workers from imminent harm
Under CMAA standards, the CM has the authority and responsibility to stop work when an imminent danger to life safety exists, pending corrective action.
In statistical quality control, what does a control chart's Upper Control Limit (UCL) represent?
Answer: Three standard deviations above the process mean, indicating a statistically unusual result
The UCL is set at three standard deviations above the process mean; a data point above it signals the process may be out of statistical control.
Which risk identification technique involves a structured, anonymous survey of experts across multiple rounds to reach consensus on risk likelihood?
Answer: Delphi Technique
The Delphi Technique uses iterative anonymous questionnaires sent to a panel of experts, allowing independent opinions to converge toward consensus without groupthink.
What does a project's Experience Modification Rate (EMR) primarily measure?
Answer: A contractor's past workers' compensation claims relative to industry average
EMR compares a contractor's actual workers' compensation losses to the expected losses for the industry, with 1.0 being average; above 1.0 indicates higher-than-average risk.
A project team decides to redesign a foundation to eliminate the need for deep excavation in unstable soil. This risk response is BEST classified as:
Answer: Risk avoidance
Risk avoidance eliminates the threat entirely by changing the project plan so the risk-causing activity no longer exists.
Which sampling method divides a population into subgroups and randomly samples from each subgroup proportionally?
Answer: Stratified sampling
Stratified sampling divides the population into distinct subgroups (strata) and draws random samples from each, ensuring proportional representation of all subgroups.
