Quality Control & Process Improvement Flashcards

In quality control terminology, what is a 'tolerance' in construction work?

Answer: The acceptable range of variation from a specified measurement

Tolerance defines how far a measurement can deviate from the target value and still be considered acceptable.

A handyman discovers mid-project that the lumber delivered has a higher moisture content than specified. The BEST quality control response is to:

Answer: Document the issue and notify the client before proceeding

Documenting the non-conforming material and informing the client preserves the client relationship and protects the handyman from liability for future failures.

Which approach best demonstrates continuous process improvement when bidding jobs?

Answer: Comparing estimated vs. actual material costs after each job to refine future quotes

Tracking estimation accuracy against actual costs reveals systematic errors and improves bid precision over time.

When installing a ceiling fan, what quality check should be performed BEFORE drywall work is considered complete?

Answer: Confirm the electrical box is rated for a ceiling fan's dynamic load

Standard electrical boxes are not rated for the dynamic (swinging) load of a ceiling fan and can fail, so verifying the box rating before closing drywall prevents a dangerous hidden defect.

A handyman performs a 'pre-job walkthrough' with the client before starting work. This quality control step primarily helps to:

Answer: Align expectations and document existing damage before work begins

A documented walkthrough establishes shared understanding of scope and pre-existing conditions, preventing disputes about responsibility for damage.

What is the MOST effective way to verify that a newly installed GFCI outlet is functioning correctly?

Answer: Press the TEST button and verify the outlet loses power, then RESET to restore it

The TEST/RESET cycle confirms both the trip mechanism and reset function are working, which is the purpose-built verification method.

Which behavior indicates a handyman is using a 'Plan-Do-Check-Act' (PDCA) improvement cycle on their business?

Answer: Testing a new scheduling app for one month, reviewing whether on-time rates improved, then deciding whether to keep it

Running a time-limited trial, measuring a specific outcome, and making a data-driven decision follows the PDCA cycle exactly.
