A client requests that a CEAC consultant verify whether a previously completed accessibility report meets current 2010 ADAAG standards. This type of review is BEST classified as:
Answer: A third-party quality audit
An independent review of a prior report against current standards by a separate qualified party constitutes a third-party quality audit.
To reduce variability in measuring accessible counter heights across a team of five inspectors, the MOST effective process improvement is:
Answer: Conducting a gauge repeatability and reproducibility (GR&R) study and retraining inspectors with high variability
A GR&R study quantifies how much variation comes from the measurement system versus individual inspectors, allowing targeted retraining of those causing the most variability.
In Six Sigma terminology, a CEAC consultant defining the scope, goals, and deliverables of an accessibility QC improvement project is performing which DMAIC phase?
Answer: Define
The Define phase establishes the problem statement, project scope, goals, and stakeholders before data collection or analysis begins.
A firm tracks the number of accessibility report corrections requested by clients each month. If January shows 12, February 9, March 14, and April 8, what is the MOST useful next step?
Answer: Plot the data on a control chart to distinguish common-cause from special-cause variation
Plotting monthly correction counts on a control chart reveals whether variation is random (common cause) or signals a significant process change (special cause) requiring investigation.
Which scenario represents a 'false negative' quality error in an accessibility survey?
Answer: Documenting a non-compliant feature as compliant, leaving a barrier unreported
A false negative occurs when a real deficiency is missed and recorded as compliant, which is the most serious quality error because it allows barriers to persist unaddressed.
A process flow analysis of an accessibility report reveals a two-day bottleneck where completed field notes wait for CAD drawing updates before the report can be finalized. The BEST immediate process improvement is:
Answer: Initiate CAD drawing updates in parallel with field note write-up rather than sequentially
Running the CAD update and field note write-up concurrently (parallelizing tasks) eliminates the sequential wait time without sacrificing deliverable quality.
A CEAC consultant uses a fishbone (Ishikawa) diagram to investigate why accessible restroom findings have a 15% error rate. Which categories are MOST relevant for the cause branches?
Answer: People, methods, measurement tools, environment, materials, training
A fishbone diagram for process errors typically uses the 6M categories — people, methods, measurement, machines/tools, environment, and materials — to systematically explore all potential causes.
