CEAC Quality Control & Process Improvement 2

Question 1

When conducting a QC audit of accessibility documentation, which discrepancy is MOST critical to flag?

Accepted Answer

Measured door clear width recorded as 31 inches when ADA requires 32 inches minimum

Answer

A door clear width of 31 inches falls below the 32-inch ADA minimum, making it a code-compliance failure that must be flagged and corrected.

Question 2

A process improvement team wants to reduce re-inspection rates on accessibility surveys. Which Lean tool is BEST suited to identify the root cause of recurring measurement errors?

Accepted Answer

5 Whys analysis

Answer

The 5 Whys technique iteratively asks why a defect occurred until the root cause is identified, making it ideal for diagnosing recurring measurement errors.

Question 3

Under a QC checklist system for CEAC field assessments, what is the primary purpose of a 'sign-off' step by a second consultant?

Accepted Answer

To ensure an independent review catches omissions or measurement discrepancies

Answer

A secondary sign-off provides an independent check that prevents errors from reaching the final report, upholding the accuracy standards required for accessibility compliance work.

Question 4

A CEAC consultant notices that 20% of submitted transition strip measurements are consistently 0.25 inches above actual field conditions. This is BEST described as:

Accepted Answer

Systematic bias in the measurement process

Answer

A consistent directional offset across many measurements indicates systematic bias, likely from a calibration error or procedural flaw rather than random variation.

Question 5

Which statistical method is most appropriate for monitoring whether a batch of ramp slope measurements remains within ADA compliance limits over time?

Accepted Answer

Control chart (SPC)

Answer

Statistical process control (SPC) control charts track measurements over time and signal when a process drifts outside acceptable limits.
